The KIKUSUI PWR401MH is a compact 400 W wide-range programmable DC power supply rated for up to 240 V and 5 A. It provides CV/CC operation for applications requiring higher DC voltage with moderate current in a compact 400 W platform.
LAN/LXI, USB, and RS232C are standard, with built-in sequence control, VMCB multi-channel operation, variable internal resistance, and remote sensing for automated test and R&D systems.
The KIKUSUI PWR401MH is a compact programmable CV/CC DC power supply designed for applications that require output voltages up to 240 V while maintaining flexible voltage and current combinations within a 400 W output-power envelope.
The PWR401MH provides a rated output of 240 V, 5 A, and 400 W, with maximum settable values of 252 V and 5.25 A. Its wide-range architecture allows the user to select different voltage and current operating points without requiring separate fixed-range DC supplies, provided the total output remains within the unit's rated power capability.
Built-in hardware sequencing, analog control, variable internal resistance, preset memory, remote sensing, synchronized operation, and Virtual Multi-Channel Bus functionality make the PWR401MH suitable for both standalone engineering use and integrated automated test systems.
Provides higher-voltage DC output up to 240 V and current up to 5 A while supporting flexible operating points within the 400 W rated output-power limit.
Constant-voltage setting accuracy is ±(0.05% of setting + 0.05% of rating), with ±26 mV line and load regulation. Constant-current setting accuracy is ±(0.5% of setting + 0.1% of rating).
One hardware sequence program with up to 64 steps can be stored in the power supply. Step time ranges from 0.1 seconds to 100 hours, and stored programs can run without a connected PC after programming.
In CV mode, the PWR401MH can simulate source internal resistance from 0.01 Ω to 36.00 Ω for evaluating systems using battery, solar-cell, fuel-cell, or other source models.
Standard digital interfaces support remote programming and automated testing. LAN supports LXI, VXI-11, SCPI-RAW, and HiSLIP communication.
Virtual Multi-Channel Bus technology allows one PC to control up to 31 PWR-01 units through a virtual multi-channel power-system architecture.
