Key Features
Wide-range Constant-power Output
One supply covers many voltage/current combinations within its 1500 W power envelope, improving utilisation compared with fixed rectangular-output DC supplies.
CV / CC Priority Selection
Choose voltage-priority or current-priority behaviour to reduce overshoot and inrush risk when powering capacitive loads, batteries and sensitive DUTs.
Adjustable Voltage and Current Slew Rates
Programmable ramp-up and ramp-down rates help control charging current and DUT stress during power sequencing and transient tests.
Remote Sense and Output Discharge
4-wire remote sense compensates cable drop at the DUT, while the internal discharge circuit safely bleeds output energy after shutdown.
Local List Mode and Analog Control
Run up to 50 local list steps and use external analog voltage control plus voltage/current monitoring outputs for system integration.
Rack-friendly Remote Operation
1U, 19-inch rack format with USB and LAN interfaces, browser-based control and optional USB-GPIB for automated production or burn-in racks.

Applications
Automated Burn-in and Production
1U format, LAN/USB control and parallel expansion for DC burn-in racks and production power systems.
Battery and BMS Test
Programmable DC source for battery-pack, BMS, charger and protection-circuit validation within the model voltage/current envelope.
DC-DC Converter Characterisation
Wide-range constant-power output supports converter input sweeps, current-limit tests and controlled power sequencing.
Controlled Inrush Testing
Adjustable slew rate and CV/CC priority reduce inrush stress during capacitor, bus and high-current load testing.
Rack Power Supply
Compact programmable DC source for university, R&D and validation benches that need higher power than small bench supplies.
