Cdbw-250kVA Single-Phase Industrial Grade Anti-Interference Purification AVR Automatic/Manual Power Frequency AC Voltage Stabilizer/ Regulator

Product Description

Product Description
This stabilizer can eliminate the interference of clutter and pulse spikes in the power arid to the equipment. When the external power supply network voltage fluctuations or load changes cause voltage fluctuations, it can automatically maintain the stability of the output voltage.

Input Voltage	Single-phase 176V~264V, three-phase four-wire, phase voltage 175V~250V, line voltage 304V~456V
Output Voltage	Single-phase 220V / Three-phase 380V
Output Accuracy	1~5% (Adjustable)
Frequency	50Hz/60Hz
Effectiveness	≥98%
Responding Speed	≤1.5s
Ambient Temperature	-10ºC~+40ºC
Insulation Resistance	≥5MΩ
Overload Capacity	Double the rated current for one minute
Waveform Distortion	Pure sine wave output
Protective Funtion Anti-interference/lightning strike Filtering Performance	Overvoltage, overcurrent, phase loss, and phase spike input 4000V pulse width 2s, output less than 2v, 25kA peak high current 0.4us impact 2 times frequency 0.15M~10G insertion loss, plug-in mode 70~100dB, common mode 100dB.

Protection:

Over and under voltage protection	When the input voltage exceeds the voltage regulator's over-voltage or under-voltage value, the equipment will automatically protect the no-voltage output.
Over current protection	When the current exceeds the rated value, the input is automatically cut off.
Overload, short circuit protection	When the load exceeds the specified overload capacity or short circuit of the equipment, the power supply can be automatically cut off within the specified time.
Limit protection	When the brush operation exceeds the area, the adjustment is automatically terminated.
Mains bypass function	When the voltage stabilizer needs maintenance or malfunctions, the manual switch can be switched to supply power in a direct connection state.
True effective sampling circuit control	High accuracy, good sensitivity, good measurement rate and frequency characteristics, high input impedance, low output impedance, wide power supply range and low power consumption.
Back to middle function	When the sampling voltage is lower than the lower limit reference voltage or higher than the upper limit reference voltage, the brush will automatically return to the center.
