Kepco Series KES Engine Start Battery Chargers are wall-mounted units which charge 12-, 24- or 48-Volt, lead-acid or nickel-cadmium batteries used in engine start applications. The series is arranged in three groups:

12-Volt KES Models:

• KES 12-20 Rated at 20 Amperes
• KES 12-40 Rated at 40 Amperes

24-Volt KES Models:

• KES 24-10 Rated at 10 Amperes
• KES 24-20 Rated at 20 Amperes
• KES 24-50 Rated at 50 Amperes

48-Volt KES Models:

• KES 48-5 Rated at 5 Amperes
• KES 48-10 Rated at 10 Amperes
• KES 48-25 Rated at 25 Amperes

The output voltage and output current limit are factory set, and are adjustable from the front panel recessed trimpots. An optional temperature compensation probe provides automatic adjustment of the float voltage to accommodate temperatures from 0° to 35°C.

Units may be operated with a nominal 100V a-c to 240V a-c (input voltage range 85 to 265 Va-c), 50-60 Hz nominal, range 47-66Hz. Both AC lines are protected by fuses. A front panel ammeter shows charging current.

A front panel CHARGER ON indicator lights while input power is applied to the a-c input terminals and the unit is operational. The front panel TEMP PROBE NOT CONNECTED indicator lights to show that the temperature compensation probe is not attached to the unit. An internal diode network across the output provides protection in the event that the battery connections are reversed, causing the front panel circuit breaker to open.
