Input voltage

120, 208, 220, 240, 277, 480 or 600 V AC, single-phase/three-phase, 60 Hz ± 6% (50 Hz optional).

Output voltage 

24, 48, 110, 125, 220 or 250 V DC, other output voltages are available on request.

Output current

10, 20, 30, 40, 50, 60, 80, 100, ..., 600 A (50 to 100% adjustment range).

Voltage regulation

± 0.25% for a 0 to 100% load fluctuation of the rated output current, combined with an input voltage fluctuation of ± 10%, combined with a frequency fluctuation of ± 5%. No batteries are connected to the system when measurements are taken.

Communication

2 Ethernet ports (each optical and metal) (DNP3, HTTPS).

Residual ripple

2% RMS of the output voltage for the same conditions specified in “Voltage regulation”.

Efficiency

90%, at full charge.

Protection

input: thermal magnetic circuit breaker; output: thermal magnetic circuit breaker (2 poles)

Ventilation

natural convection except for the battery section, which may be provided with a fan (system with vented battery in the same cabinet as the battery charger).

Acoustical noise

less than 65 dbA at one meter, at nominal power.

Climatic conditions

operating temperature: -10°C to 50°C

storage temperature: -20°C to 70°C

relative humidity: 0 to 95% at 25°C
