AC input

Input system

DC input (SSU); 220 V AC single-phase input (rectifier)

Input frequency

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

Power factor (PF)

≥ 0.99 (rated input and load)

DC output

Output voltage range

–42 V DC to –58 V DC

Default output voltage

–53.5 V DC

Maximum output power

• 21,000 W (only AC input)
• 24,000 W (AC input and PV input)

Regulated voltage precision

≤ ±1% (output voltage of within 53.5 V ±0.1 V at 50% load)

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 sharing 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

≤ 80 V AC

AC input undervoltage recovery threshold

80–90 V AC

DC output protection

DC output overvoltage protection threshold

–58.5 V DC to –60.5 V DC

• If overvoltage occurs due to an internal fault, the rectifier locks out.
• If the external voltage is greater than –63 V DC for more than 500 ms, the rectifier locks out.

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

Safety

IEC/EN60950-1/GB 4943 and CE certification

Mean time between failures (MTBF)

200,000 hours (at 25°C)
