Description
Electrical data
“Vin” Input (protected against undervoltage)
- 36 to 75V (accidental max.: 100V / 0.1s)
- no load consumption: ≤ 220mA at 48V
- possible external time-delay fuse: 60A
- optional “on/off” remote control
“Vout” Output
- 24V / 28V / 48V (≤ 60V / 900W option); accuracy: 1%
- optional fit with embedded “10 revolutions” axis: 24V output: ± 3%; 48V output: 0 to -10%
- 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 ≤ 52W)
- dynamic response: < 1 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” will reinforce protection
- “inversion Vin” option: internal diode (external fuse required)
- abnormal temperature rise: automatic shutdown and restarting
- total sealing IP67
Thermal and environmental performances
- storage: -55 to +125°C; operating: -40 to +85°C
- cooling: natural convection (derating ≈ 4% per °C)
- temperature rise of the case, at full load: ≤ 26°C
- maximum ambient temperature: 60°C at full power (72°C with optional ventilation 4 m/s), 72°C at half power
- vibrations, shocks, humidity: protection by epoxy resin
Standards and specifications
- marking CE / UL / C UL60950-1 / RoHS
- flammability for PA2002: UL94HB, horizontal test
- MTBF: > 250,000 hours, case at 25°C
- worldwide manufacturers for active parts
- assembling and final controls: ELECDAN-CONVERTER
Available options (please contact us)
