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 HMR80360:
The HMR80360 model is the most powerful 10 kW variant in the series and delivers up to 80 V DC at 360 A. Compared to the other models, the HMR80360 is characterized by high output current at lower voltage. This makes it particularly suitable for applications with high currents, such as motor, battery and low-voltage power tests.
The other models in the series cover higher voltages at lower currents, e.g. For example:
- HMR65046 - 650 V / 46 A (10 kW)
- HMR130023 - 1300 V / 23 A (10 kW)
- HMR500108 - 500 V / 108 A (18 kW)
- HMR195027 - 1950 V / 27 A (18 kW)
