500W isolated DC/DC converters with very large input range and very high efficiency

420.00 456.00  excluding tax

500W modules converting 36 to 75V into 12V or 13.8V / 500W with a 95% efficiency. Optimized shapes and volumes are enabling effective heat dissipation. Two presentations:

  • 1CIHR: integrated dynamic cooling with a mini tubed fan, fast racking-out for fan replacement directly by the user after 50,000 hours. Case 64 x 64 mm, thin (33 mm), weldable on printed circuit.
  • 3HR: passive dissipation through natural convection. To be mounted on wall or DIN rail, either on front or side. Case 112 x 120 x 37 mm, equipped with four screw connectors for wire sections ≤ 40mm2.

Input voltage Vin: 36 to 75V.

Ouput voltage Vout: 12V, 13.8V.

Description

Electrical data

“Vin” Input (protected against undervoltage)

  • 36 or 42 to 75V (accidental max.: 100V / 0.1s)
  • no load consumption: 100mA at 48V
  • possible external time-delay fuse: 30A
  • optional “on/off” remote control

“Vout” Output

  • 12V and 13.8V; accuracy: 1%
  • fit, only for the 12V output: ±5%: optional with embedded “10 revolutions” axis for case 3HR; external with “trim” pin for case 1CIHR
  • line regulation: < 4.10-3 of Vout
  • load regulation: ≤1%
  • temperature coefficient: ≤ 10-4 of Vout, per °C
  • switching frequency: fixed (≈ 130 kHz)
  • residual ripple: ≤1% of Vout
  • nominal efficiency: 95% (losses ≈ 26W)
  • dynamic response: < 0.5 ms, with 25% load variation
  • permissive capacitive load: 1,200µF to ≥ 15,000µF depending on load

Protections

  • input-output insulation: 1500V DC. Internal filter on the input
  • against overload and short circuit (even constant)
  • in case of inductive load: option “L” 3HR will reinforce protection
  • “inversion Vin” option 3HR: internal diode (external fuse required)
  • abnormal temperature rise: automatic shutdown and restarting
  • total sealing IP67 (except fan for case 1CIHR)

Thermal and environmental performances

  • storage: -55 to +125°C; operating: -40 to +85°C
  • cooling case 3HR: natural convection (derating 2.5% per °C)
  • temperature rise of the case, at full load: 39°C
  • maximum ambient temperature at full power: 45°C for case 3HR; 50°C for case 1CIHR
  • maximum ambient temperature at half power: 65°C for case 3HR; 70°C for case 1CIHR
  • vibrations, shocks, humidity: protection by epoxy resin

Standards and specifications

  • marking CE/UL60950-1, ICE60950-1, EN60950-1 / RoHS
  • flammability for PA2002: UL94HB, horizontal test
  • MTBF case 3HR: > 500,000 hours, case at 25°C
  • MTBF fan (easy rapid unplugging): 50,000 hours
  • worldwide manufacturers for active parts
  • assembling and final controls: ELECDAN-CONVERTER

Available options for case 3HR (please contact us)

  • Vout fit with axis “10 revolutions”
  • inductive load driving
  • “ON / OFF” remote control
  • symmetrical dissipator
  • “inversion” protection
