Product Highlights
SENS FC and FCA battery chargers offer accurate, automatic
charging of lead-acid and nickel-cadmium batteries. Unlike unregulated "battery
boilers" or poorly regulated ferro-resonant chargers, the output voltage
automatically adjusts to changing input, load, battery and ambient conditions.
This prevents battery overcharging and consequent loss of battery electrolyte.
SENS FC/FCA chargers are ideal for either lead-acid or nickel-cadmium
batteries.
Standard FC features include AC line compensation, precision
voltage regulation, current limiting, automatic 2-rate charging, voltmeter
and ammeter, temperature compensation, and UL listing in most sizes.
The FCA offers, in addition, a comprehensive alarm system that
meets NFPA requirements.
Specifications
Input Frequency & Voltage
Range
60 Hz standard; 50 Hz optional, +5%.
120 volt standard; 100, 208, 230, 277, 380, 480 volt optional, +10%.
Output Voltage
- 12, 24, or 32 volts nominal.
- Float voltage adjustable from 100% to 120% of nominal.
- Equalize voltage adjusts to 15% above float voltage.
Output Voltage Regulation
+1% of the correct temperature compensated value from no load to
full load with simultaneous variations in input voltage of 10% and frequency
of 5%.
AUTOBOOST
 (See Figure 1)
After battery discharge or AC failure, the charger operates in the high-rate
constant current mode until the battery voltage rises to the pre-set BOOST
(EQUALIZE) level. The charger will operate in this constant voltage BOOST
mode until the battery's current acceptance falls to 70% of the charger's
rating. At this point, the charger reverts to the lower FLOAT voltage,
where it remains until another battery discharge or AC failure.
Temperature Compensation
 (See Figure
2)
All batteries have a negative temperature coefficient. SENS FC/FCA is
equipped with the appropriate temperature compensation (-0.2% per deg.
C) to assure correct charging in all conditions. Remote sensing of battery
temperature is optional.
Current Limiting & Overload Protection
- Soft start - ensures smooth start-up.
- Electronically current limited at 110% of rated output.
- AC & DC fuses (6 & 10 A units).
- AC & DC breakers (20 & 25 A units).
Controls & Adjustments
- Separate internal adjustment for float & boost voltages.
- Separate internal adjustment for low and high DC alarms.
Indicators
DC voltmeter: 2.5" scale (64mm).
DC ammeter: 2.5" scale (64mm).
Alarm indicators and remote contacts optional. ( See Alarm Systems Table.)
Ambient
Operating temperature: -10 C to +50 C.
Humidity: 5% to 95% non-condensing.
Optional Features
- Alarms (see Model Number Breakout).
- Non-standard input voltage.
- Export packaging.
- Fungus proofing of circuit boards.
- NEMA 3R housing.
- Remote temperature sensing.
How To Order
- Determine standard charger model number. Refer to the Ordering Information
Table and Model Number Breakout.
- If nonstandard input, alarm system or float/equalize control are required,
please contact the factory to verify the correct part number.
- Specify options as line items (e.g. remote temperature sensing).
