INTRODUCTION
The SR100A range is designed for use as a very accurate AC to DC power supply, or float charger for lead
acid batteries.
Note that for float charging the output voltage must be set to approximately 15% above the
nominal battery voltage.
time of order for all higher voltage models.

CONNECTIONS
If used as a float charger always connect the positive output of the power supply to the positive terminal of
the battery. The charger may be permanently connected to float charge lead acid batteries but it is essen-
tial to periodically check the electrolyte level of flooded cells as there is always some evaporation.
To minimize the volt drop at the output connections use all the terminals provided ie. connect output wires in
parallel.
CONNECTION LAYOUTS
AC INPUT
ALARM VERSIONS
Relay contacts shown in de-enegised state (ie when there is a fault condition).
Alarm relays are energised when power supply is operating normally, eg. "Power" alarm relay is energised
when ac input is present.
