The KP 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 Supplies with regenerative capability
The KP series is a bidirectional DC power supply designed with regenerative capability, making it optimal for evaluating in-car inverters for hybrid and electric vehicles, motors, generators, large capacity batteries, and capacitors. It is also suitable for wind or solar power generation applications. With a wide lineup ranging from 2 kW to 120 kW, you can select the ideal model for various stages of development and production.
* Designed for regenerated power to be consumed on the premises.
Features and Benefits
- Extensive product lineup with over 20 models ranging from 2 kW to 120 kW.
- Regenerative capability ensures energy-efficient operation.
- Supports master-slave parallel operation.
- Redundant operation ensures the system continues to function even if a single unit fails. (Please consult us for details.)
- Scalable configuration allows for future expansion (up to 120 kW).
- Seamless switching between power running (source) and regeneration (sink) modes.
- High efficiency reduces heat generation and suppresses ambient temperature rise.
Applications
The KP series serves as both a regenerative electronic load and a power supply for:
- Evaluation of HEV/EV inverters and motors
- Testing of large-capacity batteries and capacitors
- Solar and wind power generation system testing
- Evaluation of generators and alternators
* This model is not designed for self-sustained (islanding) operation. Output stops when the grid power is disconnected.
The model that may be used as a battery simulator will be available soon. Contact our sales staff for details.
