Option
 |
The
PPS15-3 is a 13.8 volt 15amp transformer isolated switch
mode down converter designed to be used either as a stand
alone supply or as a float style battery backed up supply
when a lead acid battery is connected to its battery
terminals.

PSTR 7412 Locomotive DC- DC Converter
 |
The PS 7412 has been
designed for locomotives with DC supplies ranging from 60 to
130 volts, without any voltage selection being needed.
|

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.
