This unit can improve the braking function of the transducer. It feeds the energy generated duiing the braking process back to the power grid without affecting the braking effect. With this unit, the feedback effiency can reach 95%, which shows powerful energy saving.
Feature:
Power grid range: 380V AC ±20%; 50Hz±10%
Medium-speed and high-speed passenger elevators and freight elevators
low harmonic distortion: the total harmonic distortion(THD) of feedback current is less than 5%, which complies with the IEC6 1000-3-2 and GB/T14549 standards.
High-speed IGBTswitch: less swithc cost, high running effciency, and ow noise.
Display module: it displays the bus voltage and feedback current.
, response time ≤2ms, reliable and stable running.
