ETP48400-C9A4 Datasheet

ETP48400-C9A4

Specifications

AC input

Input system

220/380 V AC three-phase four-wire (default), compatible with 127/220 V AC three-live wire

Input frequency

45–66 Hz (rated frequency: 50 Hz or 60 Hz)

Power factor (PF)

≥ 0.99 (rated input, with 100% loads)

DC output

Output voltage range

–42 V DC to –58 V DC

Default output voltage

–53.5 V DC

Maximum output power

24000 W (supports N+1 backup; maximum total output current does not exceed 400 A; and long-term operating current output does not exceed 350 A).

Regulated voltage precision

≤ ±1% (The output voltage is within 53.5 V DC ±0.1 under 50% loads.)

Peak-to-peak noise voltage

≤ 200 mV (rated input voltage and 0%–100% load)

Psophometrically weighted noise

≤ 2 mV (300–3400 Hz; input power ≤ 264 V AC)

Current sharing imbalance

≤ ±5% (50%–100% load)

AC input protection

AC input overvoltage protection threshold

≥ 300 V AC

AC input overvoltage recovery threshold

290 V AC–300 V AC

AC input undervoltage protection threshold

≤ 80 V AC

AC input undervoltage recovery threshold

80 V AC–90 V AC

DC output protection

DC output overvoltage protection threshold

–58.5 V DC to –60.5 V DC

  • If overvoltage occurs inside a rectifier, the rectifier locks out.
  • If the external voltage is greater than -63 V DC for more than 500 ms, the rectifier locks out.

AC surge protection

Nominal lightning strike discharge current: 30 kA (8/20 µs); maximum lightning strike discharge current: 60 kA (8/20 µs)

DC surge protection

Differential mode: 10 kA (8/20 µs); common mode: 20 kA (8/20 µs)

Safety

IEC/EN60950-1 and GB4943, TLC and CE certifications

MTBF

200,000 hours (at 25°C)
