Mid Voltage DC Cycler and Emulator System Benefits

Save Resources

Boasting more than 90 percent power recovery, the system results in significant electrical cost savings and rapid response times.

Expand Range as Needed

You can test power ranges from 12 kW modules up to 252 kW with 40 or 120 V bidirectional DC loads.

Scale Test and Simulation

The system offers a full-function tester per channel with minimal output capacitance to ensure precise battery simulation, and you can include up to three modules per system.

Emulate and Simulate Safely and Precisely

The system offers accurate emulation of real-world conditions, including sub-millisecond transitions, over/undercharged battery simulation, BMS, and failures.
