PRODUCT DESCRIPTION
1.1
The
Micro
ARE-M series of single-phase, controlled ferroresonant float chargers is intended for utility,
communications, and other applications where a source of stable, electrically clean, reliable DC power is
needed. Available models provide an output voltage of 24 VDC and an output current from 6-100
amperes, depending upon model. Refer the Model Designation for a list of standard models and options.
Installation is quick and easy. The design accommodates floor, wall, or rack mounting with standard and
optional brackets. A mounting method is usually specified on the equipment order so the proper brackets
can be supplied.
The charger is configured and operated from the front of the unit. The control section includes a 2-line
digital display, 4-button keypad, green AC on LED and a red alarm LED, an AC input circuit breaker, and
a DC output circuit breaker. An optional control board offers front panel LED indicators, showing the
status of the High Voltage Alarm, Low Voltage Alarm, No Charge Alarm and AC Fail Alarm on the
telecom models. For the utility models two additional LEDs show the state of the Positive and Negative
ground fault alarms.
Access to internal components for servicing by qualified personnel is through the door comprising the
front of the unit. The door is hinged on the left and secured on the right by two fasteners.
