I — INTRODUCTION
SCOPE OF MANUAL.
This instruction manual covers the installation and operation of the Kepco Series KES 12 Volt Engine Start Battery Chargers (see
Table 1).
WARNINGS and CAUTIONS
• Do not operate the unit without proper grounding. Improper grounding risks an electric shock that could result in
injury or death.
• Do not touch the unit’s input or output terminals to avoid the risk of electric shock that could result in injury or death.
Energy stored in the unit’s output capacitor is present on the DC OUTPUT terminals for a few seconds even after the
a-c input voltage is removed.
• The Float Voltage and Current Limit must be preset prior to starting the initial charge to avoid damage to the battery
being charged.
• To avoid damage to the unit or the battery being charged, never obstruct the ventilation holes at the sides of the unit.
The unit must be installed in a properly ventilated area, free of smoke and corrosive or explosive vapors.
DESCRIPTION.
The Kepco Series 12 Volt Engine Start Battery Chargers are wall-mounted unit designed to charge 12-Volt lead-acid or nickel cadmium
batteries used in engine start applications. Model KES 12-20 is rated at 20 Amps, Model 12-40 is rated at 40 Amps. The output voltage
and output current limit are factory set, and are adjustable from the front panel recessed trimpots (see Table 1 for values). An optional
temperature compensation probe (not supplied) 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 (see Table 1, Note 1). Both AC lines are protected by fuses. A front panel ammeter shows charging current.
The heart of the KES 12 Volt Series is a solid-state switching power supply, Kepco’s RKW, which has an integral cooling fan. A front
panel CHARGER ON indicator lights while the unit is on. 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.
