User Inputs
t)Temperature Probe: Provides input for battery voltage temperature compensation. This feature operates only when the probe is attached.
u)User Alarm Inputs: Four inputs are provided for user alarm inputs. The inputs are designed for isolated contacts tied from the alarm input to a corresponding
4.3. Load Management
Distribution is included for up to 2 circuit breakers or 12 GMT fuses per 50 Amp shelf. The circuit breakers can be 2 X 30 Amps or 1 X 60 Amps in each shelf. The GMT fuses are 8 X ¼ to 15 Amps in each shelf. When a circuit breaker trips, a normally open switch closes and the controller reports a CB alarm. Alarms are reported when a breaker is tripped or is manually turned off.
When a GMT fuse trips, a fuse element burns out allowing the indicator to connect DC power to the alarm contact and the controller reports a fuse alarm.
4.4. Battery Management
Battery Charging
Battery charging and protection are integrated into the DC power system to support the primary function of providing power to the load.
Battery Temperature Compensation
The Battery Float Voltage is based on the value recommended by the battery manufacturer in order to maintain correct battery charge at 25ºC. As temperature rises, electrochemical activity in a battery increases. Similarly, as temperature falls, electrochemical activity in a battery decreases. As temperature rises, charging voltage should be reduced to prevent overcharge and increased as temperature falls to prevent undercharge. The DC power system uses Battery Temperature compensation to change output voltage to compensate for temperature changes.
The circuitry is designed to produce a temperature compensation slope of
