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 Silvertel’s Power over Ethernet (PoE) module, the Ag102 can
charge SLA batteries from power obtained over an Ethernet cable.
