Ag102

V1.6 June 2014 Datasheet Ag102 Silvertel Intelligent Sealed Lead Acid Battery Charger Module PbPb 1 Features Multi-Stage Charging Battery Reversal Protection Reduced Power Consumption Wide DC or AC Input Voltage Range High Efficiency DC-DC Converter Intelligent Top-up Float Charge Programmable Charge Current Battery Condition Indicator Output Temperature Compensation Overload & Short-circuit Protection Simple Integration 2 Description The Ag102 is a micro-processor based intelligent, cost effective, sealed lead acid (SLA) battery charging module. It uses digital technology to optimise the charging of standard, 12V sealed lead acid batteries between 1.2Ah and 7Ah capacity. Using various intelligent charging techniques the Ag102 technology will maximise the manufacturers specified battery lifetime. The Ag102 has a very wide input range of 9V to 36V DC. This gives extensive flexibility and means the system and charger requires just one, lower cost, power supply. When used in conjunction with Silvertels Power over Ethernet (PoE) module, the Ag102 can charge SLA batteries from power obtained over an Ethernet cable.
