Dynamic Braking Unit (DBKU)

Features
1. High braking capability: brake continuously for full load when braking rate is 10%; brake for 30s for full load when braking rate is 100%.
2. Wide voltage range: offer two braking threshold voltage.
3. The communication terminal of the dynamic braking unit uses plug-pull type with free wiring mode.
4. The input terminals' space reaches 20mm for convenient wiring to achieve better braking capability and better cooling result.
5. Comprehensive protection function: prevent inverter from short circuit of braking resistor.
6. The braking voltage of the dynamic braking unit is optional. The braking initial voltage by exterior terminal can be set at 680Vor 720V.
7. Reliable multi-protection: overcurrent, short circuit and overheat protection, fast and efficient.
8. Multi-principal and subordinate control function: up to 4 braking units can be used together.
9. Braking enabling control: this function can protect the dynamic braking unit and avoid the fault caused by overcurrent and overvoltage.

Typical Application
The dynamic braking unit is used for elevators, cranes, etc.
