Certified by UL to EN54-4:1997 +A1 +A2. Up to 1.2A current to load at 27.6V dc nominal regulated output. Charging capability to support 1.2 to 7Ah batteries. Electronic overload protection shuts down output until overload or short circuit is removed. Battery Monitor detects battery missing, low battery, short-circuit or reverse connection or circuit impedance (Ri) in excess of 500mW, caused by connector or wiring problem/corrosion, within 4 hours. Battery charging circuit is energised only when a battery is correctly connected and the battery voltage is greater than 14 V. No loss of output during automatic connection of battery to load on loss of mains. Deep discharge protection disconnects battery from load when battery voltage falls below 21 V. Diagnostic indicator LED (Orange) (Internal). Fault indicator LED (Yellow) flashes on detection of output fault, battery fault, charger fault and mains failure. Mains indicator LED (Green) showing mains present Indicators check at start-up. Optional RS232 serial interface for fault reporting and diagnostics. Suitable to fit batteries up to 2 x 1.2Ah 'T' Box Power Supply - 300h x 240w x 63d (mm) Hinged Lid
