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
