WES13-3 Adapt to the reliability of the power grid

The technical characteristics of WES13-3 are mainly reflected in the high reliability proven by years of safe operation experience:

1. Adapt to the reliability of the power grid

WES13-3 has a wide operating voltage range, and can operate in the power grid when the rated voltage fluctuates between -45% and+15%. Can output at full load when the rated voltage fluctuates from -10% to+10%; The voltage is within -45%, which has no impact on the operation of the frequency converter and can continue to operate with reduced rating; When the voltage of the WES13-3 bus is below -45%, the frequency converter stops. This is also unique among similar products (usually only able to run up to -30%).

WES13-3 has the function of instantaneous power outage and recovery, which reliably ensures continuous operation without tripping during instantaneous power outage (the time can be set by software). Within 5 cycles after the instantaneous power outage of the frequency converter device, the frequency converter remains operational; If it exceeds 5 cycles, WES13-3 can choose to shut down according to different load inertia, or track the motor speed and automatically increase the output frequency to the given value after the input voltage returns to normal. If the power outage time exceeds X seconds (M-N seconds can be customized), the frequency converter protection will shut down.
