2.3 BATTERY
On the HALLEY/E 20-30kVA UPS, the battery can be installed inside the UPS for
autonomy from 5 up to 15 minutes depending on the UPS power (see following table); if
the requested back-up time is longer the battery is installed inside external cabinets. On
the HALLEY/E 40÷80kVA UPS the battery is always installed in external cabinets.
The battery charger control logic is completely integrated inside the total-controlled rectifier
control board; the battery is charged, according to the DIN 41773 Standard, every time it
has been partially or completely discharged and it is kept floating, even when it’s charged,
to compensate any auto-discharge.
