CHARGERS/RECTIFIERS - RAIL SIGNAL & COMMUNICATION |
INTRODUCTION
 The ERB-C RACKMOUNT CHARGERS provide constant current or constant voltage modes for charging stationary batteries. Line compensation prevents fluctuations in AC input from affecting DC output. The state-of-the-art regulator control circuit compensates for the DC cable connecting the charger to the batteries. A battery sensing cable is available to read battery voltage directly from batteries for improved accuracy.
The output voltage and current are controlled by a microprocessor which also monitors the internal components of the charger for any deviation in performance. An internal ambient temperature sensor is connected to the microprocessor. This information can be used to compensate the battery voltage for temperature and to prevent the charger from damage by extreme temperature. An option is available for remote battery temperature sensing. The charger will also record temperature limits. A power fault counter to record the number of power faults that have occurred and a timer to indicate the length of time in days from the last power fault are also provided.

| Float Voltage Per Cell: |
1 to 2.99 volts |
| Temperature compensation: |
0.0 to -9.9 mV per cell degrees Fahrenheit |
| Current Limiting: |
DC output limiting will be at maximum rate set |
| Low Output Ripple: |
Ripple voltage at the battery terminals is less than 0.25 Vpp at full output current. Ripple voltage at the battery terminal is less than 0.06 Vpp at 2.0 Amps output current. |
| Over Temperature: |
Using the charger ambient temperature, the output will start to cut back at 145 degrees Fahrenheit and will stop its output at 160 degrees Fahrenheit.
Using an external battery temperature probe, the output will start to cut back at 130 degrees Fahrenheit |
| Output/Input connections: |
Connections are binding posts located on the back side of the unit. This is for protection against shock or injury. |
