Description


Kikusui PWX750LF DC Power Supply

PWX750LF: The Kikusui PWX750LF is a 0-30V 0-75A (750W max) CV/CC programmable regulated DC power supply designed to be optimised for a rack-mounted power supply. To increase its mounting efficiency, 19-inch rack width which is only 1U high with cooling running from the front to the back which means units can be stacked on top of each other. The PWX750LF is equipped standard with USB, RS-232C, and LAN interfaces, which are essential for system integration. The PWX750LF also has a virtual multi-channel bus (VMCB) function that allows it to be used efficiently for many different remote control and monitoring architectures. In particular, the LAN interface is LXI compliant*, enabling you to control and monitor the power supply easily from a browser on a PC, smartphone, or tablet. You can also manage the power supply in a different building.

Features:

  • A wide range of voltage and current settings can be combined within its output power rating (3 times)
  • PFC circuit of 0.99 (with 100 V) or 0.97 (with 200 V) at full load *TYP value
  • Universal input voltage (85 V to 265 V)
  • LAN (LXI compliant) /USB/RS-232C fitted as standard
  • A virtual multi-channel bus (VMCB) function makes multi-channel operation more efficient
  • Emulation setting, Command language setting function
  • Expandable output capacity (parallel operation)
  • External analogue control function (Output control based on voltage and resistance; ON/OFF based on contact signals)
  • Analogue monitor output (output voltage, output current, and operating mode can be monitored)
  • Various protection functions: overvoltage protection, overcurrent protection, and overheat protection
  • Memory function (3 combinations of settings for voltage, current, OVP, OCP, and UVL)
  • Remote sensing function
  • Bleeder circuit ON/OFF setting (to prevent over-discharging of batteries)
  • CV, CC priority start function (prevents overshoot with output ON)Variable Internal Resistance Feature (Factory option *Exclude PWX750ML)
