If the battery voltage drops below 9.7 / 18.7V the load is switched off. On when BBU is charging the batteries. Off when the “Full Charge” LED is on. “Fault” LED (red): On when AC fails. On when external power supply voltage is <11 / 21.5V. On when batteries not connected. On when battery voltage is <9.7 / 18.7V Fault relay de-energizes for the above conditions. “Battery Open” LED (red): “Drain” input “Drain Reset” “Enable” input 991628 0012 85Vac, 120Vdc 115-230Vac, +/- 10% 265Vac, 300Vdc 991628 0024 85Vac, 120Vdc 115-230Vac, +/- 10% 265Vac, 300Vdc @ 115Vac @ 230Vac 0.80A 0.50A 1.0A 0.60A 9.2A max. 9.0A max. 10A minus the input current 2A slow blow (internal) Thermistor Varistor 2A slow blow (internal) Thermistor Varistor 10Ω 275Vac Switching Frequency 100KHz 100KHz Efficiency @ Max Charge 69% 72% 120-200mA 120-200mA <50mV <50mV Input Current AC Current Output for PS On when battery voltage is 14.75 / 29.5V or greater. “Bat Status” relay is energized. Once fully charged the BBU drops the charge voltage to 13.65 / 27.3V (“float” voltage). “Charging” LED (yellow): “Battery Reverse” LED (red): minimum typical maximum Catalog Number Input Voltage Batteries connected in reverse. Fault relay de-energizes and fault LED turns on. Internal fuse opens to prevent damage to BBU or batteries. No batteries connected - takes approx. 60 seconds to detect after turning on BBU. “Fault” LED is on and Fault relay is de-energized. A temporary short between the “Drain” and “COM” terminals switches the load to the batteries until the battery voltage reaches 11 / 22V. At this point the AC power is returned to the power supply and the BBU starts recharging the batteries.

A connection between the “Enable” and “COM” terminals enables the BBU. If terminals are open circuit (Disabled) the BBU functions as a battery charger only. In the event of AC failure the batteries are not connected to the load via the BBU. The BBU is factory preset as Enabled. fuse inrush current overvoltage Notes Battery Charger Output Approvals/Certifications Miscellaneous Red LED on when open approximately 90% of battery voltage
