Dynamic Braking Unit (DBKU)
Features
1. Highbraking capability: brake continuously forfull load when braking rate is 10%; brake for 30s for full load when brakingrate is 100%.
2. Wide voltagerange: offer two braking threshold voltage.
3. The communicationterminal of the dynamic braking unit uses plug-pulltype with free wiring mode.
4. The input terminals’space reaches 20mmfor convenient wiring to achieve better braking capability and better coolingresult.
5. Comprehensive protection function: prevent inverter from short circuit of brakingresistor.
6. The braking voltage of the dynamic braking unit is optional. The braking initial voltage by exteriorterminal can be set at 680Vor 720V.
7. Reliable multi-protection: overcurrent, short circuit and overheatprotection, fast and efficient.
8. Multi-principal and subordinate control function: up to 4 braking units canbe used together.
9. Braking enabling control: this function can protect the dynamic braking unitand avoid the fault caused by overcurrent and overvoltage.
TypicalApplication
The dynamic brakingunit is used for elevators, cranes, etc.
