Wide-Range 230 V DC Power in a 1U Platform
The KIKUSUI PWX750MHF is a 750 W programmable DC power supply designed for applications that require a higher-voltage operating range together with flexible CV/CC operation and automated system control.
The PWX750MHF provides a rated output of 230 V and 10 A within a 750 W wide-range operating envelope. Rather than operating as a conventional single-range supply, voltage and current can be combined across the MHF operating area while remaining within the unit's rated output power.

The 1U rack-oriented platform also supports remote sensing, analog control, master-slave parallel operation, series connection, network-based monitoring, and software-controlled sequence testing for integration into automated DC power test systems.
230 V / 10 A / 750 W MHF Output
The PWX750MHF combines a 230 V rated voltage range with up to 10 A output current and 750 W rated power for higher-voltage DC test requirements.
Wide-Range CV/CC Operation
Voltage and current can be varied across the MHF operating area while remaining within the 750 W power envelope, allowing one supply to cover multiple voltage and current combinations.
1U Rack-Oriented Design
The low-profile chassis and front-to-rear forced-air cooling are designed for efficient rack installation and integration into automated test systems.
LAN, USB, and RS232C Standard
Standard digital interfaces support remote programming and monitoring. The LAN interface supports LXI 1.3 Class C and browser-based access through the built-in web server.
Master-Slave Parallel Operation
Up to four PWX750MHF units of the same model can be operated in master-slave parallel configuration to increase available output current and system power.
Series Operation
Two PWX750MHF units of the same model can be connected in series when a higher combined output voltage is required.
Analog Control and Monitoring
The rear-panel J1 interface supports external voltage and current programming, output control, shutdown, alarm clear, and voltage/current monitoring functions.
Comprehensive Protection Functions
Protection includes overvoltage, overcurrent, undervoltage limit, overtemperature, fan failure, sensing error, low AC input, shutdown, power-limit, and communication watchdog functions.
Higher-voltage DC device and module evaluation up to 230 V
Automated DC power testing in rack-mounted test systems
Power supply and power-conversion equipment development
DC-powered server and electronic system evaluation
Network-controlled R&D and production test systems
Battery, solar-battery, and fuel-cell source simulation with the optional variable internal resistance function
