                                         PS2024 and PS4012 Emergency Vehicle Battery Manager

 

The PS2024 is designed as on vehicle battery chargers and battery charge state monitors. While the vehicle is at its base or station, the charger is connected to the AC mains supply. An ignition interlock relay on the charger prevents starting the vehicle when the AC mains are on. The charger first applies a fast charge to bring the battery up to nominal capacity and then applies a trickle charge to maintain that state.

                                          Carclub- 1 Amp Precise Charger

This product is designed to give a 1 amp maximum 13.9 V precise voltage & current limit suitable for charging 12 volt nominal lead acid cells. When it reaches this accurate set point, the charger supplies a small trickle charge to maintain the battery. For sealed batteries, there can be no venting, as the current is precisely limited. For open cells, there is no out gassing. Therefore the charger cannot damage the battery.
