AC Input and Voltage Selection for All-O-Matic DC Gate Operators

The All-O-Matic EMI-PCB Power Board is a genuine replacement power supply board used across All-O-Matic DC gate operators. Installed in the operator's power supply assembly, it manages the incoming single-phase AC connection and provides the voltage-selection and protection functions between the incoming line power and the rest of the operator's electrical system.

The board supports All-O-Matic DC operators configured for either 115 VAC or 230 VAC single-phase power. A voltage selector switch allows the installer to match the board to the site's incoming power, while dedicated LINE 1, LINE 2, and GND terminals provide the field power connections.

The EMI-PCB also incorporates an onboard fuse and electrical protection circuitry. Replacement may be necessary when the operator has proper incoming AC power but the power supply section no longer provides the expected output, or when troubleshooting identifies a failed EMI/power supply board.

Key Features

Conclusion

The All-O-Matic EMI-PCB is the correct replacement when servicing the AC input power supply section of an All-O-Matic DC gate operator equipped with this board. Because the operator may be wired for either 115 VAC or 230 VAC, the voltage selector and incoming power wiring must be set correctly before power is applied.

When replacing the board during a no-power or power-supply diagnosis, confirm the incoming voltage, fuse condition, wiring, transformer, and related power-supply components before determining that the EMI-PCB itself has failed.
