The HMR series from B&K Precision comprises high-performance, multi-range (autoranging) DC power supplies with 10 kW and 18 kW output power in a compact 3 U-rack form factor. Thanks to the multi-range technology, each model can provide its rated power at different voltage/current combinations and thus replace several conventional fixed-range power supplies.
The series is designed for ATE systems (Automated Test Equipment) and laboratory/manufacturing environments where high output currents or voltages and at the same time fast control times and low noise are required. Typical areas of application include testing power electronics, drives, batteries, motors, transformers and other inductive or capacitive loads.
- Multi-range operation up to 1950 V or 360 A
- Master/slave operation with up to 1,8 MW total power (100 units in parallel)
- SiC MOSFET technology for high efficiency (up to 95%) and reliability
- Large 5-inch touch display with rotary encoders and secure output on/off button
- LXI-compliant LAN and USB interface as standard, optional GPIB and analog interface
- Configurable internal resistance for battery simulation
- Extensive protection functions: OVP, OCP, OPP, OTP, Key-Lock
- 3 U height, 200 - 415 V AC input, thermostatically controlled fans
Variant HMR500108:
The HMR500108 model is an 18 kW variant of the series and supplies up to 500 V DC at 108 A. It combines a medium output voltage with high current and higher total power, making it ideal for applications with power-intensive DC loads, e.g. in e-mobility, motor and drive testing or testing DC link components.
The other models in the series differ as follows:
- HMR80360 - 80 V / 360 A (10 kW) - for high currents at low voltage
- HMR65046 - 650 V / 46 A (10 kW) - for higher voltages at moderate current
- HMR130023 - 1300 V / 23 A (10 kW) - for very high voltages at low current
- HMR195027 - 1950 V / 27 A (18 kW) - highest voltage in the series for high-voltage tests
