Auto Source Change Over with Current Limiter - ACCL

While monitoring the Generator supply, Allows only limited load and functions as load limiter as per desired current.

Current sealing while monitoring the DG and EB will be factory-Set.(Field selectable Model-Optional)

Whenever the load current exceeds the preset limit, power is automatically switched-off and resets after 9sec and trips again if the overload exists, this cycle is ( 3Sec ON & 6Sec OFF) is repeated every nine seconds. If overloading on DG persists the ACCL enters lock out mode after 5 ON & OFF cycles. The unit can be reset manually by reset switch. However tailor made units i.e field adaptable as per customer requirement can be provided as it is a microcontroller based.

Display of each Phase Voltage, Current and Frequency in Three Phase ACCL by 2 line 16 character LCD.

Over Voltage and Under Voltage cut-off limit for both EB and DG and is optional

On the resumption of the EB main supply, ACCL changes over from DG to EB and allows the full load current.
