Specifications

AC input

AC input system

110 V AC dual-live wire

AC input voltage

85 V AC-300 V AC

Input frequency

Frequency range: 45-66 Hz; nominal frequency: 50 Hz or 60 Hz

Power factor

≥ 0.99 (rated input and load)

Total harmonic distortion (THD)

≤ 5% (Vin = 208 V AC, 220 V AC, 230 V AC, 50%-100% load)

DC output

Output voltage range

-42 V DC to -58 V DC

Default output voltage

-53.5 V DC

Output power

The maximum output power is the number of rectifiers multiplied by the output power of a single rectifier.

Regulated voltage precision

≤ ±1%

Ripple and noise

≤ 200 mVp-p

Noise weighting

≤ 2 mV

Imbalance of load sharing

< ±5% (20%-100% load percentage)

AC input protection

AC input overvoltage protection threshold

> 300 V AC

AC input overvoltage recovery threshold

When the voltage is restored to 290 V AC, the output resumes.

AC input undervoltage protection threshold

< 85 V AC

AC input undervoltage recovery threshold

When the voltage is restored to 90 V AC, the output resumes.

DC output protection

DC output overvoltage protection threshold

Range: -58.5 V DC to -60.5 V DC

  1. If an overvoltage occurs inside a rectifier, the rectifier locks out.
  2. If the external voltage is above –63 V for more than 500 ms, the rectifier locks out.

AC surge protection

Level B surge protection; nominal surge discharge current: 30 kA (8/20 µs); maximum surge 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 and regulatory design

Complies with the IEC/EN60950-1.

MTBF

200,000 hours
