Battery Chargers – Sentry and Guardian Models
Features
•
High-quality constructed stainless steel cases,
suitable for wall mounting
•
Auto boost operation provides increased
output voltage when batteries are below a
preset point
•
•
Remote temperature compensation provides
control of output voltage based on temperature
Current limiting will only output the rated
current of the charger
The Sentry and Guardian battery chargers provide automatic, current limited and voltage controlled
charging to vented lead acid batteries. They may be used in a wise range of industrial charging
applications, including standby engines, pumps and generators.
Each unit consists of a transformer, rectifier and thyristor control circuit. The control circuit ensures that
the charger maintains a battery voltage at the pre-calibrated float level, while supplying any additional
load current up to the specified maximum.
