Power Supply Delay Soft Start Protection Board

$17.99
Quantity

1.Features:

  • 30A high current power supply 
  • With soft start setting 
  • High power negative temperature thermistor 
  • Its smart circuit design eliminates the need for a separate small transformer. Soft-start protects the rectifier bridge.
  • It can avoid impacting the power grid during startup, and prevent the total power supply from tripping, and has a long service life. 

2. Description:

  • Product Name: High Power Soft Start Board 
  • Input voltage: AC 220V 
  • Output Voltage: AC 220A 
  • Supply Current: 30A 
  • Power:6600W 
  • Work Temperature:-25℃~85℃
  • Work Humidity: 5%~95% RH 
  • Size:74.5*57.5*29.5mm 

3. Circuit Working Principle:

  • Turn on and delay the power on. 
  • NTC is in series with the output load circuit to reduce the startup current (delay circuit control).
  • Shorted NTC after the start is completed, and the power supply is directly output. complete the soft-start process.
