Discontinued
Achieves 10 kW power running and regenerative operation in a 6U-height, 23-inch rack size
KPE series is no longer available as we stopped the production and sales of this model in September 2020. Meanwhile, we support. PBR series is available as the successor model, and more information on the series can be found here.
PBR seriesBidirectional DC Power Supply with Power Running and Regeneration Capability
The KPE series is a bidirectional DC power supply with regeneration capability*.
While offering high baseline performance and reliability as a DC power supply, the cost is kept down, and outstanding cost performance is achieved through careful selection of the available features. It is optimal for evaluation and testing not only of in-car inverters for hybrid and electric vehicles but also of motors, generators, high-capacity vehicle batteries, and capacitors, as well as wind and solar power generation.
* The device is designed on the assumption that all regenerated power is consumed on the premises.
Features
- Bidirectional DC power supply with excellent cost performance
- Effective power utilization achieved through regeneration capability
- Smooth switching between power running and regeneration
- Reduced power consumption helps mitigate the rise in ambient temperature
Applications
The devices can be used as the regenerating electronic load and power supply device for the applications below.
- Evaluating charge/discharge testing for rechargeable batteries and capacitors (optional)
- Evaluating in-car inverters and converters
- Evaluating motors and generators
* No model supports independent operation. They stop when system power is disconnected.
Models
| Model | I/O power [kW] | Power supply mode (power running mode) | Load mode (regeneration mode) | ||
|---|---|---|---|---|---|
| DC output voltage [V] | DC output current [A] | DC input voltage [V] *2 | Maximum input current [A] | ||
| KPE200-55(10kW) *1 | 10 | 0 to 200 | 55 | 20 to 200 | -55 |
| KPE400-30(10kW) *1 | 0 to 400 | 30 | 40 to 400 | -30 | |
| KPE500-25(10kW) *1 | 0 to 500 | 25 | 50 to 500 | -25 | |
| KPE750-15(10kW) | 0 to 750 | 15 | 75 to 750 | -15 | |
- Can be manufactured for 19-inch rack type. (excluding KPE750-15 [10kW]).
For the 19-inch rack type, append "B" to the end of the model number. - The voltage range that can be regenerated at the rated current will be voltage that is approximately 10% of the rating or higher.
