It is recommended that where paralleled units are being used to float a battery before the system load is installed, only one unit be left operating.

  • Page 53: Circuit Description

    FIGURE 5-1 BLOCK DIAGRAM, TYPICAL MICRO ARE-M FLOAT CHARGER To improve the output voltage regulation against changes in load and input frequency, the chargers employ a ferroresonant transformer and UNIPOWER controlled-ferro technique, which controls the level of core saturation. This is accomplished by shunting the resonant circuit with a triac in series with an inductor. The electronic voltage/current control senses the start of the resonant capacitor charge cycle.
  • Page 54 Micro ARE-M Series 24V Chargers, Single Phase Circuit Description The power rectifier converts the AC voltage from the transformer into a DC voltage. It consists of silicon diodes arranged in a half-wave circuit. The output of the rectifier is filtered and supplied to the battery and the load through the DC circuit breaker.
