Special regulator for elevators and cranes technical Parameters
Basic indicator
Protective function
Input voltage
380V ± 20% or wide voltage special definition
Overpressure
Output exceeds rated voltage by 10% (adjustable), delay 3-5 seconds to cut off output power
Output voltage
380V±5% selectable
Undervoltage
Output exceeds rated voltage -15% (adjustable), delay 3-5 seconds to cut off output power
Voltage regulation accuracy
1-5% can be set
Delay
2 seconds to cut off the output power
Frequency
50Hz/60Hz
Short circuit
Cut off the output power when the load device is shorted
Strain time
≤0.05s
Overcurrent
When the rated output current is exceeded, the output power is cut off after 3-5 seconds delay.
Stable schedule
When the input voltage changes by 10% relative to the rated value, the stability time is ≤1s.
Reverse phase
When an error occurs in the three-phase electrical phase sequence, the machine alarms and cuts off the output power (settable)
Missing phase
When there is a phase loss in the three-phase power, the machine alarms and cuts off the output power.
Bypass
Manual or automatic pass-through device for power supply failure or repair
Other indicators
Additional waveform distortion
≤0.1%
Withstand voltage
The whole machine has no breakdown and no arcing at 2000VAC/min.
