Main Features

1. High-power bus energy storage and filtering: Absorbs voltage spikes, smoothes DC voltage and suppresses power ripple on high-voltage DC bus.

2. Absorbs power-on inrush current, buffers sudden load changes, stabilizes bus voltage and protects downstream power devices (ESCs, IGBTs, power MOSFETs).

3. High ripple current handling capability and low ESR with low heat generation, suitable for long-duration high-current operation.

4. M6 screw terminals: Screw fastening for high-current wiring with reliable contact, designed for high-power chassis mounting.

5. Built-in safety vent: Releases pressure when internal pressure becomes excessive to improve safety.

6. Wide operating temperature range, suitable for harsh industrial environments.
