1250W isolated DC/DC converter with large input range and very high efficiency

1,331.00  excluding tax

1250W (2kW peak) DCDC converter. With its optimized shape and volume for efficient natural convection cooling, this case can be mounted on wall (on the side) or on DIN rail (on front or side). Connections are made through 4 streamlined clamps for wires ≤ 40 mm2. Thermal resistance is 0.5°C/W and can be reduced to 0.25°C/W if required, with optional air flow of 4 m/s.

Input voltage Vin: 36V to 75V.

Ouput voltage Vout: 48V.

Electrical data

“Vin” Input (protected against undervoltage)

  • 36 to 75V (accidental max.: 100V / 0.1s)
  • no load consumption: 400mA at 48V
  • possible external time-delay fuse: 120A
  • optional “on/off” remote control

“Vout” Output

  • 48V; accuracy: 1%
  • optional fit with embedded “10 revolutions” axis: ± 2%
  • line regulation: < 4.10-3 of Vout
  • load regulation: ≤ 1%
  • temperature coefficient: ≤ 2.10-4 of Vout, per °C
  • residual ripple: ≤ 1% of Vout
  • nominal efficiency: 95% (losses ≈ 66W)
  • dynamic response: < 2 ms, with 25% load variation
  • permissive capacitive load: 1,200µF to ≥ 15,000µF depending on load


  • input-output insulation: 1500V DC. Internal filter on the input
  • against overload and short circuit (even constant)
  • in case of inductive load: option “L” will reinforce protection
  • “inversion Vin” option: internal diode (external fuse required)
