Battery Charger Specifications
Input Voltage Range	21-33 VDC
Output Float Voltage	27.3 VDC ±200 mV @ 20°C, temperature
	compensated at approximately -36mV/°C
	(0° C to 50° C)
Output Current Limit	1.4 A (For 6.2 – 18 Ah battery)
	3.3 A (Default; for 18-110 Ah battery)

Notes:

•AC power must be provided to the 4100U from a dedicated AC branch circuit. The AC input is supervised.

•240 VAC: The service branch circuit breaker should be sized to handle at least 150 percent of the total required by all of the power supplies in the system.

•The bulk supply (rated at 9A max) which feeds 24V Sig, 24V Card, 24V Aux also supplies the SPS Card including the on board IDNet, and the battery charger. The charger is disabled during alarms so as to make the 9A available on the other busses. (See the following table for the SPS current.)
