PWR-01 Series Compact Wide Range DC Power Supply(CV/CC)
The PWR-01 is a series of high performance, multifunctional, compact, wide-range DC power supplies. It consists of 16 models in total with 4 maximum voltage outputs (L, ML, MH, and H) and 4 maximum power outputs (400 W, 800 W, 1200 W and 2000 W). The series is equipped with LAN (LXI), USB, and RS232C as standard interfaces that are essential for system integration. The PWR-01 also features front-facing output terminals, variable internal resistance, bleeder ON/OFF functions, CC/CV priority switching function, synchronized operation, various protections, and programmable internal memory.

How many models are in the Kikusui PWR-01 series, and how do they differ?
Sixteen models total, arranged by voltage tier (L, ML, MH, H) and maximum power: 400 W, 800 W, 1200 W, or 2000 W. Pick your tier and power level, and within that model, you can mix voltage and current settings across a window roughly three to four times wider than a fixed-range supply at the same wattage.
That flexibility often means one PWR-01 can cover what two or three separate bench supplies would otherwise handle. Engineers building automated test systems around the PWR-01 will find it within a broader category of power sources for electronics manufacturing at Electrotest.
What communication interfaces does the Kikusui PWR-01 DC power supply support?
Every model has LAN (LXI-compliant), USB, and RS232C on board. The LXI side handles communication over standard Ethernet using VISA drivers, so it wires into LabVIEW, Python-VISA, or NI TestStand without custom drivers or workarounds.
The Virtual Multi-Channel Bus (VMCB) function lets you group several PWR-01 units and address them together in one communication session, which simplifies multi-rail power sequencing scripts considerably. That kind of programmability is where the PWR-01 fits naturally into R&D test benches, where test parameters change often.
What is the bleeder function on the Kikusui PWR-01, and when should it be turned off?
When you switch the PWR-01 off, the bleeder resistor pulls the output capacitors down to zero rather than leaving the voltage to decay slowly on its own. You can turn the bleeder on or off depending on what the load needs, and there is a stronger mode for when you need the drop to happen quickly.
Turn it off when the load is high-impedance or battery-like, where even a small continuous drain through the bleeder resistor would pull down the measurement or bleed charge out of the device under test. Engineers testing batteries and energy storage systems will hit this situation regularly when the PWR-01 is part of a charge-discharge rig.
Does the Kikusui PWR-01 support soft start and output-on/off delay functions?
Yes to both. Soft start ramps the voltage up rather than throwing it on in one step, so the device under test does not see a hard inrush spike at power-on. The delay timers let you control exactly when the output activates or deactivates relative to a trigger, which is useful when power rails need to come up in a specific order.
Both matter when you are testing battery management systems or automotive ECUs, where the power sequencing order and ramp rates are part of the specification, not just nice to have. The PWR-01 sits in Electrotest’s Electronic test and power source range alongside AC and DC options, covering a wide range of test requirements.
Can the Kikusui PWR-01 operate from both 110 V and 230 V mains supplies?
Yes. The PWR-01 accepts 85 V to 265 V AC input, so it runs on North American 110 V/60 Hz and European or Australasian 230 V/50 Hz mains without any adjustment. Ordinary mains fluctuations and brief brownouts do not reach the output.
For labs that send equipment between sites on different power grids, or that buy instruments they expect to use internationally, that universal input removes a real logistical headache. Organisations running multi-site calibration programmes can find instruments with similarly flexible power requirements in Electrotest’s calibration and advanced electrical range.
