The KIKUSUI PMX-A Series is a compact programmable DC power supply designed for low-noise constant-voltage (CV) and constant-current (CC) operation. Nine configurations cover output ratings from 18 V to 500 V and 35 W to 105 W.
Standard LAN (LXI), USB, and RS232C interfaces, external analog control, preset memory, and front-panel output terminals support both benchtop testing and system integration.
The KIKUSUI PMX-A Series combines a compact series-regulator design with programmable CV/CC output, low ripple and noise, and built-in digital communications.
Nine output configurations cover applications from low-voltage, higher-current bench testing to high-voltage, low-current DC supply requirements. Front-panel output terminals simplify load connections, while forced-air cooling allows the unit to be incorporated into rack-mounted measurement systems.
LAN control includes a built-in Web server for browser-based monitoring and operation. The PMX-A Series also provides external analog voltage and resistance control, monitor outputs, protection functions, and three voltage/current preset memories.
The PMX-A uses a series-regulator architecture to provide low ripple and noise compared with switching-regulator power-supply designs.
CV and CC operation supports general-purpose DC sourcing for laboratory, development, and automated electrical testing.
Models are available from 18 V / 5 A through high-voltage configurations up to 500 V / 0.1 A, allowing the supply to be selected according to the required voltage and current range.
Current setting resolution is 0.1 mA across the series, while voltage setting resolution varies by output range. The PMX18-2A provides voltage setting resolution down to 1 mV.
Standard digital interfaces support remote programming and monitoring. The LAN interface is LXI compliant and includes access through the PMX-A built-in Web server.
Output voltage and current can be controlled using external voltage or resistance signals. Voltage and current monitor signals and operating-status outputs are also available through the rear-panel interface.
Up to three combinations of voltage and current settings can be stored for quick recall from the front panel.
The 18 V and 35 V models provide remote sensing with up to 0.6 V compensation per line to reduce the effect of voltage drop in load wiring.
Selectable CV or CC priority at output startup helps suppress unwanted voltage or current overshoot when the output is turned on.
Overvoltage, overcurrent, and overheat protection monitor the supply and switch the output off when protection conditions are detected.

PMX-A power supplies support both digital network control and external analog control for benchtop and automated DC power applications.
LAN, USB, and RS232C are provided as standard communication interfaces. The LAN interface supports LXI-compatible operation and allows remote control and monitoring through the power supply's built-in Web server.
External analog control can program output voltage and current using either an external voltage or resistance signal. Voltage and current monitor outputs and operating-status signals support integration with external control and monitoring equipment.
