Silver Telecom's first battery charger module that is aimed at reducing power consumption and maximizing battery life using inelegant charging techniques and our high efficiency DC-DC converter. This module is for 12V sealed lead acid batteries between 1.2Ah and 7Ah capacity.

The Ag102 is an intelligent, cost effective sealed lead acid (SLA) battery charging module. It has been designed to optimize the charge characteristics of standard, 12V sealed lead acid batteries between 1.2Ah and 7Ah capacity. Using various intelligent charging techniques the Ag102 technology will maximize the manufacturers specified battery lifetime.

The Ag102 has a very wide input range of 9V to 36V DC. A 24V AC input would need the addition of just 2 external components. This gives extensive flexibility and means the system and charger would require just one, lower cost, power supply. Used in conjunction with Silver Telecom Power over Ethernet (PoE) modules, the Ag102 can also charge SLA batteries from an Ethernet cable.

The charging current can be programmed to match the battery capacity via external inputs. This minimizes the risk of over or under charging. Battery terminal voltage is continuously monitored. Once full capacity is reached, charging stops and to prevent over charge, float charge ‘top-ups’ are applied only when necessary. This significantly reduces the loss of battery life caused by continuous float charging.

With the addition of a low-cost thermistor, charge voltages can be temperature compensated. This further optimizes the charge cycle, helping to preserve battery life.

The Ag102 provides comprehensive charge condition indicators which can be used to monitor all battery charge and fault conditions.

With its high efficiency and intelligent charging techniques, the Ag102 is an ideal solution for reducing power consumption and maximizing SLA battery life.
