INTRODUCTION
The Auto Charge T, Model 091-80-xx battery charger is a compact completely automatic
charger designed for installation in systems which require a transient suppressed
charger. Ideal for electric utility applications to maintain the batteries used in high
voltage circuit breaker trip circuits or wherever the charger may be exposed to high
electromagnetic fields. Red, yellow and green indicators are provided to indicate
whether the battery is fully charged, charging normally or receiving the maximum current.
Construction of the Auto Charge T is extremely rugged to withstand shock and vibration.
In addition the line power input lines and the charger output terminals are provided with
filters and MOV transient suppressors. These suppression circuits permit the charger to
meet ANSI/IEEE C37.90.1-1989.
