Description


Kikusui PMX250-0.25A DC Power Supply

The PMX250-0.25, 0-250V 0-0.25A, is a compact, high-performance DC power supply that provides constant voltage (CV) and constant current (CC). It is designed to improve working efficiency for benchtop uses. For this purpose, the output terminals are located on the front panel and are ergonomically designed so that wiring harnesses for electrical loads can be connected by moving your fingers naturally. Moreover, a forced air cooling system is used to intake and exhaust of the internal air, so the unit can be rack mounted without space.

Furthermore, the PMX250-0.25 is equipped with LAN, USB, and RS232C interfaces as standard interfaces required for system operation. In particular, the LAN interface enables you to control and monitor the power supply from Web browsers on PCs, smartphones, tablets, and other terminal devices. Moreover, the PMX-A is LXI（LAN extension for Instrumentation) certified product, so it can be connected easier with your measurement system using LAN interface.
The PMX250-0.25 is also equipped with analogue external control/monitoring output, various protective functions, memory function, and other functions.

Features:

  • Series regulator system with excellent noise performance
  • High setting resolution – Voltage: 1 mV, Current: 0.1 mA (PMX18-2A)
  • Wide range of output variations (9 models are available)
  • LAN (LXI compliant) / USB / RS232C as standard interface
  • External analog remote control
  • Monitoring and status signal output
  • CV, CC priority start function (to prevent overshoot when the output is ON)
  • Remote sensing function (18V, 35V models)
  • Key lock, 3-point preset memory function
