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 24 Volt Engine Start Battery Chargers are wall-mounted units designed to charge 24-Volt lead-acid or nickelcadmium batteries used in engine start applications. Model KES 24-10 is rated at 10 Amps, Model KES 24-20 is rated at 20 Amps andModel KES 24-50 is rated at 50 Amps. The output voltage and output current limit are factory set, and are adjustable from the frontpanel recessed trimpots (see Table 1 for values). An optional temperature compensation probe (not supplied) provides automatic adjust-ment 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. Afront panel ammeter shows charging current.The heart of the KES 24 Volt Series is a solid-state switching power supply, Kepco’s RKW, which has an integral cooling fan (KES 24-50has two fans). A front panel CHARGER ON indicator lights the unit is on. The front panel TEMP PROBE NOT CONNECTED indicatorlights to show that the temperature compensation probe is not attached to the unit. An internal diode network across the output providesprotection in the event that the battery connections are reversed, causing the front panel circuit breaker to open.FIGURE 1. 24 VOLT ENGINE START BATTERY CHARGER, FRONT VIEWOPENARMCLOSED+RC-RCALARM REMOTECONTROLGNDL (L1) N (L2)AC INPUT DC OUTPUTNC- + |
