SINGLE PHASE SCR AND SCRF TYPE BATTERY CHARGER

1. SAFETY NOTICE

THERE ARE DANGEROUS VOLTAGES WITHIN THE BATTERY CHARGER CABINET.
CAUTION! READ "IMPORTANT SAFETY INSTRUCTIONS" ON PAGE I.
a. Only qualified personnel should attempt to adjust or service this equipment.
b. Refer to instruction manual for service procedures and CAUTION notes.

2. APPLICATION

a. Specifications: The silicon controlled rectifier is designed to maintain a system voltage within + or -
0.5% of the set value without exceeding its rated output current. It will maintain + or - 0.5% with input
voltage variations 10% above or below the rated input AC voltage and with 5% frequency variations.
The charger is designed, primarily, to operate only when connected to a battery load. It can be operated
as a battery eliminator into a resistive load up to full rated output at increased ripple. Filtered-type chargers
will have a ripple content less than 30 MV RMS under steady state conditions with the charger connected
to a battery having an 8-hour Amp-Hour rating of at least 4 times the full load current rating of the
charger. Other connected loads such as DC to DC power supplies or inverters, may put ripple on the
battery appreciably above 30 MV.
Unfiltered chargers should not be used with critical loads such as communication systems, amplifiers
and instrumentation systems, but should only be used for non-critical applications such as engine cranking,
etc.
This charger can be used on any number of lead-acid, nickel-cadmium, or nickel-iron cells as long as
the desired float and/or equalize voltages are within the range of the charger.

3. INSTALLATION

a. Location: Select a clean, dry location for the charger. It may be located in the battery room, but not
over the battery, and must be mounted upright. The openings for ventilation in the top, bottom and sides of
the cabinet should not be obstructed, as they provide convection cooling and ventilation. Ambient
temperatures between 32 Deg. F. and 122 Deg. F., and elevations up to 3,300 feet above sea level, will not
affect the performance of the charger. Operation at higher temperatures, or at higher elevations, is possible
if the ampere output is derated in accordance with published information, and if the charger is custom
ordered for these operating ambient conditions.
b. Wire Sizes AC: Wire sizes for the AC wiring may be selected by consulting the data on the
nameplate for input amperage. Local electrical or NEMA standards should dictate appropriate wire size.
Most codes specify that the AC wiring size must match the current rating of the input circuit breaker or
fuses.
