Description
Electrical data
“Vin” Input (protected against undervoltage)
- 200 to 400V
- no load consumption: < 10mA at 200V
- possible external time-delay fuse: 2.5A
- optional “ON/OFF” remote control
“Vout” Output
- 12V / 15V / 24V / 48V; accuracy: 1%
- optional fit with embedded “10 revolutions” axis: ±10%
- line and load regulation: < 2.10-3 of Vout
- temperature coefficient: 2.10-4 of Vout, per °C
- switching frequency: fixed (≈ 360 kHz)
- residual ripple: ≤ 1% of Vout
- nominal efficiency: 88% (losses < 34W)
- dynamic response: < 0.5 ms, with 25% load variation
- permissive capacitive load: 1,000µF to > 10,000µF depending on load
Protections
- input-output insulation: 3000V AC. Internal filter on the input
- against overload and short circuit (even constant) by limitation
- in case of inductive load: option “L” will reinforce protection
- “inversion Vin” option: internal diode (external fuse required)
- abnormal temperature rise: automatic shutdown and restarting
- total sealing IP67 (except fan for case 1)
Thermal and environmental performances
- storage case 3: -40 to +100°C; operating case 3: -40 to +90°C
- cooling case 3: natural convection (derating 2.5% per °C)
- temperature rise of the case, at full load: < 35°C
- maximum ambient temperature at full power: 50°C for case 3; 60°C for case 1
- maximum ambient temperature at half power: 70°C for cases 3 and 1
- 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 3: > 150,000 hours, case at 25°C (MIL-HB217E)
- MTBF fan (easy rapid unplugging): 50,000 hours
- worldwide manufacturers for active parts
- assembling and final controls: ELECDAN-CONVERTER
