Improper grounding risks an electric shock that could result ininjury 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 thea-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 batterybeing 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 KES 48 Volt Engine Start Battery Chargers are wall-mounted units designed to charge 48-Volt lead-acid or nickelcadmium batteries used in engine start applications. Model KES 48-5 is rated at 5 Amps, Model KES 48-10 is rated at 10 Amps, andModel 48-25 is rated at 25 Amps.The output voltage and output current limit are factory set, and are adjustable from the front panelrecessed trimpots (see Table 1 for values). An optional temperature compensation probe (not supplied) provides automatic adjustmentof 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 (inputvoltage 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 frontpanel ammeter shows charging current.The heart of the KES 48 Volt Series is a solid-state switching power supply, Kepco’s RKW, which has an integral cooling fan. A frontpanel CHARGER ON indicator lights while the unit is on. The front panel TEMP PROBE NOT CONNECTED indicator lights to show thatthe temperature compensation probe is not attached to the unit. An internal diode network across the output provides protection in theevent that the battery connections are reversed, causing the front panel circuit breaker to open.FIGURE 1.
