Specifications
A–4 975-0187-01-01
Temperature SpecificationsProtection Features
Nominal ambient 25 °C (77 °F)
Operating range 0 – 50°C (32 – 122 °F)
Current de-rating approx. 2% (Imax) / °C (50 – 65 °C) (122 – 149°F)
Storage -40 – 80°C (-40 – 176 °F)
Humidity 5 – 95%, RH non-condensing
Battery reverse polarity No damage incurred by reverse polarity.
Safe non-operating battery voltage 35 VDC maximum
Over-voltage limits The XCSeries will stop charging any bank that has a
voltage greater than + 0.5V over the temperature
compensated absorption voltage. It will restart when
this voltage is + 0.2V.
Output current limit XC3012: 30 – 33ADC
XC5012: 50 – 55ADC
XC1524: 15 – 16.5ADC
XC2524: 25 – 27.5 ADC
Over-temperature Internal charger temperature is measured. Unit shuts
down and restarts as follows:
Over-temperature shutdown at 75°C (167°F)
Over-temperature restart at 70°C (158°F)
Current derating in ambient
temperatures Rated current to 50 °C (122 °F)
2%/ °C derating above 50 °C (122 °F)
Battery over-temperature
protection Battery temperature, as sensed by the battery
temperature sensor (if installed), results in the
charger no longer charging the individual battery or
bank at a battery temperature of 55 °C (132°F).
