ETP48200-C5C4-001

AC input

Input system

127/220 V AC three-phase three-wire, compatible with 220/380 V AC three-phase four-wire

Input frequency

45–65 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

Max. output power

8700 W

Regulated voltage precision

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

Peak-to-peak noise voltage

≤ 200 mV (rated input voltage and load)

Psophometrically weighted noise

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

Current imbalance

≤ ±5% (50%–100% load)

AC input protection

AC input overvoltage protection threshold

≥ 300 V AC

AC input overvoltage recovery threshold

290–300 V AC

AC input undervoltage protection threshold

≤ 85 V AC

AC input undervoltage recovery threshold

85–90 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.
