Dc screen accessory unit MTJK03-ACDY switching unit

Features:

The effective value of two-channel three-phase AC (three-phase four-wire) voltage is measured and displayed as six-channel phase voltage (six-route voltage). Measure the effective value of AC current in the online working loop (1 route current);

Test the working state of two AC contactors (i.e. test the working state of the main and standby AC power supplies);

According to the detected dual-AC voltage, the two AC inputs are automatically switched, with the primary AC circuit and the second AC circuit as the standby circuit.

The detected AC voltage is judged and the alarm information is given. And make the corresponding processing, through the RS485 bus communication with the main monitor.
