Senlan SZ20G Series Braking Units

SZ20G series braking units can be worked with braking resistance in order to absorb regenerated electrical power when braking mo

 Detail technical specification of Braking units

1. High preformance braking capacity-braking continuously at full load, the braking rate is 50%.

2. can be continously working at rated current, more pieces can be worked at the same time, which can increase braking capacity.

3.Braking voltage can be selected, factory setting is 680V±1.5%.

4 Faulty relay outputting: The relay is broken and terminal TB is connected TC when occurs faulty, TA is connected TC without faulty.

5. Complete protective function including overhot, overcurrent(150% rated current) and overload protective functions
