When customers ask for a comparison of RD6006 vs RD6006P, I usually do not start with ‘the newer one is better.’ That would be too simple, and for bench power supplies, it is not always true.
Both models are 60V / 6A adjustable DC bench power supplies in an assembled whole-set form. They are not bare modules that require users to build a case, wire an input supply, and test everything before use. The set is already installed in a metal enclosure and comes with the input power supply, output cable, AC power cord, communication cable, external temperature sensor, and backup fuse.
The real question is this:
Do you need a normal 60V 6A bench supply, or do you need to see smaller voltage and current changes on the display?
That is where the RD6006P becomes different.

That is where the RD6006P becomes different.
The main difference: RD6006P gives you finer display resolution
| Item | RD6006 | RD6006P | What it means in real use |
|---|---|---|---|
| Voltage display resolution | 0.01V | 0.001V | RD6006P can show 1 mV-level changes |
| Current display resolution | 0.001A | 0.0001A | RD6006P can show 0.1 mA-level changes |
| Output class | 60V / 6A | 60V / 6A | Same voltage and current class |
| Max output power class | 360W | 360W | RD6006P is not a higher-power model |
| Product form | Assembled whole set | Assembled whole set | Both are ready-to-use bench units |
| PC software control | Supported | Supported | Windows 7 or above |
| Protection functions | OVP / OCP / OTP | OVP / OCP / OTP | Both support practical bench protection |
This is the part buyers should understand clearly: RD6006P is not mainly about more watts. It is about more visible detail.
For example, if you are adjusting a 5V rail, the RD6006 shows voltage in 0.01V steps. That is already enough for many repair, testing, and hobby electronics tasks. But if you are trimming a circuit and want to watch the output move from 5.001V to 5.006V, the RD6006P display makes that change visible.
The same applies to current. RD6006 displays current down to 0.001A, which is 1 mA. RD6006P displays current down to 0.0001A, which is 0.1 mA. For LED strips, motors, relays, fans, and most module testing, 1 mA resolution is usually fine. For low-power boards, sensor circuits, analog front ends, or standby-current observation, the extra digit on RD6006P is more useful.
One important note: display resolution is not the same as calibration accuracy. If you are doing formal calibration, production QA, or metrology work, you should still verify with a calibrated multimeter or electronic load. The RD6006P gives you a finer readout; it should not be treated as a replacement for a lab calibration instrument.

When I recommend RD6006
I recommend the RD6006 when the buyer wants a practical, finished bench power supply for everyday work.
It makes sense for:
It makes sense for:
- powering 3.3V, 5V, 12V, 24V, and 48V circuits
- electronics repair and troubleshooting
- testing relays, fans, motors, LED modules, and control boards
- learning constant-voltage and constant-current operation
- battery-related experiments handled by experienced users
- users who want a complete assembled unit instead of a DIY power module
For most bench tasks, the RD6006 gives enough detail. A display resolution of 0.01V and 0.001A is not “low” in normal use. If the load current is 1.5A or 3A, watching every 0.1 mA does not usually change the decision you make.
In other words, if your work is mainly repair, module testing, or general electronics development, the RD6006 is the more straightforward choice.

When I recommend RD6006P
I recommend the RD6006P when the buyer cares about small changes and wants to read them directly from the front panel or software interface.
It is the better choice for:
It is the better choice for:
- low-current circuit testing
- analog circuit adjustment
- sensor board development
- standby-current observation
- small-current charging and discharge observation
- repeatable test setups where stored voltage/current values need finer visible digits
- users who frequently compare small changes in current draw
The current display is the most practical upgrade here. A change from 0.0032A to 0.0037A looks meaningful on RD6006P. On RD6006, that same movement may be rounded into fewer visible steps. If you often test low-power devices, that extra digit saves time because you do not need to connect an external meter just to notice small movement.
I would not suggest buying RD6006P only because it “sounds better.” If the load is a heater, motor, LED bar, amplifier, or power board drawing several amps, the finer display may not bring much value. But for engineers working around small signals, standby current, and repeatable bench settings, RD6006P is easier to live with.

What makes this assembled RD series different from ordinary adjustable DC supplies?
When comparing RD6006 vs RD6006P with ordinary adjustable DC power supplies, they look similar on paper: voltage knob, current knob, digital display, output terminals. The RD6006 and RD6006P are different mainly because they combine a module-style interface with a finished bench instrument format.
1.It is an assembled whole set, not a bare DIY module
Many low-cost programmable supplies are sold as separate modules. That means users still need to prepare an enclosure, input power supply, wiring, fuse protection, output terminals, and cooling.
This RD6006 / RD6006P whole set is already assembled in a case. For users who care more about testing circuits than building the power supply itself, this matters. It reduces setup time and avoids many wiring mistakes.
The body size is about 336 mm × 173 mm × 92 mm, which is compact enough for a crowded bench but still large enough to feel like a real instrument instead of a loose module.

2.The interface is more useful than a simple two-knob supply
The front panel gives you a numeric keypad, encoder knob, silicone buttons, output ON/OFF control, memory buttons, OVP and OCP setting buttons, and a color display.
This is more efficient than turning a coarse knob for every adjustment. When I want 12.000V or 24.000V, I prefer direct entry. When I want to switch between several common test setups, memory storage is faster than resetting voltage and current from scratch.
The unit supports storing and recalling multiple setting groups, which is useful for repeated tests such as:

- 5V logic board test
- 12V fan test
- LED constant-current test
- battery pre-charge setup
- 24V control board test
3.The screen is not just decorative
The display can switch between classic, detailed, and curve-style views. It also supports a Nixie-style display mode and custom color settings.
The curve view is useful when the load is not steady. For example, a wireless module, motor driver, or charging circuit may pull current in pulses. A basic display only shows the number at that moment; the curve view helps you see whether the load is stable, rising, dropping, or pulsing.
That is especially useful on RD6006P, because the finer current readout makes small changes easier to observe.

4.Practical protection: OVP, OCP, and OTP
Both models support:
- OVP: over-voltage protection
- OCP: over-current protection
- OTP: over-temperature protection
When the output exceeds the protection value, the unit can stop output to protect the device under test.
There is one detail worth understanding. If the OCP value is set lower than the current setting, a short circuit will shut down the output for protection. If the OCP value is higher than the current setting, a short circuit can enter constant-current mode instead. That behavior is useful when testing constant-current loads such as high-power LED modules, but it also means the user should set protection values deliberately rather than randomly.

5.PC software and APP control are helpful, but check the limitations
Both RD6006 and RD6006P support PC software monitoring and control. For long tests, this is useful because you can observe voltage/current curves, adjust settings, and perform firmware updates from a computer.
The PC software is intended for Windows 7 or above. If PC control is critical for your workflow, I suggest installing and testing the software before purchase or before deploying it in a production environment.
Mobile APP control is also available, but it requires an optional WiFi board. The WiFi connection supports 2.4GHz only, not 5GHz. During WiFi communication, the physical buttons may be locked, which is normal behavior for this control mode.
This is not a flaw, but it is something buyers should know before ordering. If you need remote control, make sure the WiFi board is included or ordered together.

6.Battery charging is possible, but it is not for careless use
The green charging terminals are designed for battery charging applications, and both models can be used in battery-related work.
However, I only recommend this function to users who understand battery chemistry, voltage limits, current limits, temperature rise, and charging safety. Incorrect settings can damage the battery or create fire risk.

RD6006 vs RD6006P: which one should you choose?
Choose RD6006 if you want a complete, ready-to-use 60V 6A adjustable DC power supply for general bench work. It is the practical choice for repair, testing, education, and normal electronics development.
Choose RD6006P if your work benefits from seeing smaller voltage and current changes. The 0.001V voltage display and 0.0001A current display make it better for low-current boards, analog circuits, sensor modules, standby-current checking, and more careful test records.
I would summarize it this way:
RD6006 is the practical bench choice. RD6006P is the better choice when fine readout matters.

FAQ
In the RD6006 vs RD6006P comparison, is the P version more powerful?
No. Both are in the 60V / 6A / 360W class. RD6006P mainly gives a finer display resolution, not higher output power.
Does RD6006P have better accuracy?
RD6006P has finer displayed precision: 0.001V and 0.0001A. That does not automatically mean it replaces a calibrated meter. For formal measurement, use external calibrated equipment.
Is the RD6006 whole set ready to use?
Yes. This is an assembled whole set with case, input power supply, cables, communication cable, external temperature sensor, and backup fuse.
Can I control RD6006 or RD6006P from a phone?
Yes, but the WiFi board is required. The WiFi function supports 2.4GHz networks only, not 5GHz.
Which model is better for electronics repair?
For most repair work, RD6006 is enough. If you often diagnose low-current standby circuits or need finer current observation, RD6006P is more convenient.
