Beschreibung

This power supply solution for Protection Relays handles an ultra-wide range of both AC (88-276V AC) and DC (24-250V DC) inputs making it a suitable platform to power a variety of Protection Relays. The power supply is designed to output industry standard voltages (such as +/- 12V and isolated 6.75V) required in many Protection Relays while also providing excellent line and load regulation (< +/- 3%). This solution has been engineered for high wattage (30W) with good efficiency (up to 78%) and has also been pre-compliance tested for IEC61000-4 (EFT and Surge) and CISPR 11 Class A (Interference).

Eigenschaften

  • Ultra-wide range AC (88-276V AC) and DC (24-250V DC) input handling enables usage in a variety of Protection Relays and RTUs
  • Accurate outputs with excellent load and line regulation in the 3% range
  • Platform solution with High wattage (30W) capability while providing efficiencies up to 78%
  • Confidence from passing Pre-Compliance testing - IEC61000-4 (EFT and Surge) and CISPR 11 Class A (Interference)
  • Generates multiple industry standard voltages (+12V and -12V) and isolated supply (6.75V)
