750 W Wide-Range DC Power for Low-Voltage, High-Current Testing
The KIKUSUI PWX750LF is a programmable CV/CC DC power supply rated for 750 W, 30 V, and 75 A, designed for applications that require substantial current at relatively low DC voltages.
Unlike a conventional single-range supply, the PWX750LF allows voltage and current combinations to be selected across a wide operating area while remaining within its 750 W output-power limit. This enables one supply to cover multiple low-voltage and high-current operating points for component evaluation, automotive electronics, battery-connected systems, and automated production testing.
750 W
Rated output power
30 V / 75 A
Low-voltage, high-current output capability
Wide-Range CV / CC
Flexible voltage and current combinations within the rated power envelope
LAN / USB / RS232C
Standard interfaces for remote and automated control
Its 1U rack-mount architecture, standard LXI-compatible LAN interface, VMCB multi-channel control capability, analog control connections, and master-slave parallel operation make the PWX750LF suitable for both standalone engineering work and integrated test systems.
30 V / 75 A / 750 W Output
The PWX750LF provides a rated output of 30 V, 75 A, and 750 W for low-voltage applications requiring substantial DC current.
Wide-Range CV/CC Operation
Voltage and current can be combined across a wide operating range within the 750 W power limit, reducing the need for multiple fixed-range power supplies.
1U Rack-Mount Design
A 43 mm-high chassis and front-to-rear cooling architecture support high-density integration into automated and multi-channel test racks.
LAN/LXI, USB, and RS232C
Standard digital interfaces support remote programming and monitoring. The LAN interface is compliant with LXI 1.3 Class C and includes an embedded web server.
Analog Programming and Monitoring
Rear-panel analog connections support external voltage and current programming, output on/off control, shutdown control, alarm clearing, and voltage/current monitor outputs.
Expandable Output Capacity
Up to four PWX750LF units of the same model can operate in master-slave parallel configuration. Up to two same-model units can also be connected in series.
Low-voltage, high-current electronic component evaluation
Automotive ECU and electronic-system power testing
Battery-connected DC source and power-system evaluation
LED and other DC-powered device testing
Automated production and inspection systems
Multi-channel rack-mounted R&D and validation systems
