Part #: SPC-10(PW)




Static Inverter

Part Number :

  • Static inverted designed to power 115VAC 400Hz @ 250VA / 26 VAC 400Hz @ 150VA or the combination of max continuous power of 250VA for instrumentation, navigation, and electronic systems
  • Accepts 24-32 VDC input (normal range)
  • AC output isolated from DC input and from chassis ground
  • 26VAC output is tapped from 115VAC output transformer winding
  • Common AC return may be grounded
  • Internal trim pot provided to adjust 115/26 VAC outputs to +-10% simultaneously
  • 400Hz 115VAC resonant output transformer and PWM switching transistors on primary side in conjunction with feed choke are used to produce the power conversion
  • Control circuitry includes use of PWM integrated circuit for voltage regulation and overload current limit
  • Protection circuitry includes a low/high input voltage shutdown, low/high output frequency shutdown, output overvoltage limit, and output short circuit current limit
  • Fault monitor circuitry includes fault indication upon high/low input voltage, high/low output voltage and high/low output frequency conditions
