KGS公司SPC-75( )系列逆变器

SPC-75( )系列逆变器

The SPC-75( ) static inverter utilizes solid state circuitry to convert 28 VDC to 115 VAC, 400 Hz sine wave power. Design features include transformerless square to sine power conversion permitting light weight and reliable operation. The SPC-75( ) is capable of delivering an overload of 150% of rated power for a duration not less than five minutes under all environmental conditions.


技术参数

FEATURES:

  • Foldback current limit during overload.
  • 200% output current capability for fault clearance.
  • Remote on-off feature to eliminate the need for a heavy and expensive solenoid.
  • Shut down in the event of Low/Hi frequency and overvoltage malfunction.
  • Soft start logic in conjunction with step input and any restart after output short, output shutdown or remote off. Prevents inverter from drawing heavy surge current during start transition.
  • Fault monitor output for malfunction indication.
