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 HMR195027:
The HMR195027 model is the voltage top variant with 18 kW power of the series and delivers up to 1950 V DC at 27 A. It is specially designed for high-voltage testing and development applications, such as high-voltage battery and insulation testing, testing of inverters, HV-DC links as well as research and development in e-mobility and energy technology.
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 medium to high voltages at moderate current
- HMR130023 - 1300 V / 23 A (10 kW) - for very high voltages at low current
- HMR500108 - 500 V / 108 A (18 kW) - higher power at medium voltage and higher current
