Compensated voltage regulator technical parameters

Input	Input voltage	3Φ4W+G  AC380V-400V or special voltage on demand
	Input frequency	50/60HZ
Output	Output voltage adjustment range	3Φ4W+G ; Conventional product: AC380V±20%; applicable to voltage regulation ratio (low pressure: high voltage) within 1:2; can be customized: 380V±25%, 380V±30%, 380V±35%; or other special voltage range
	Pressure regulation method	1. Panel manual jog voltage regulation (not regulated); 2. Panel multi-turn potentiometer voltage regulation and voltage regulation.
	Manual voltage regulation accuracy	Line voltage average within ±0.5%
	Automatic voltage regulation accuracy	Line voltage average within ±1%
	Response time	≤ 0.05s
	Stable schedule	≤1s(The input voltage is changed by 5% from the rated value or the load changes)
	Waveform distortion	Increment≤0.5%
	Efficiency	≥97℅
	Three-phase unbalance	Unbalanced increment≤0.5%
	Delayed output	Regulate first and then output (protect the device from impact)
Protection	Missing phase	With (alarm and automatically cut off the output)
	Overload	Thermal protection: When the rated load is exceeded, the output power is cut off according to the inverse time limit.
	Overcurrent	Circuit breaker protection: When the rated output current is exceeded, the output power is cut off according to the inverse time limit.
	Short circuit	Circuit breaker protection: instantaneous cut off output
	Bypass	When the regulator is faulty or repaired, it has a manual power supply through.
Control operation indication	Control	SBW-B type high precision control board - integrated comparison logic control circuit
	Operating	With manual boost, buck, mains, voltage regulator (panel manual multi-turn potentiometer adjustment), stop function
	Line voltage, current	It has three-phase input line voltages UAB, UBC, UCA, three-phase output line voltages Uab, Ubc, Uca, and the true rms value of the regulator operating currents Ia, Ib, Ic. Switch the display content by pressing the button →, ← in the lower right corner of the header
