The power module for the ADC-VDB770, fitted at the chime so the doorbell draws steady power from a circuit that was only ever designed to ring a bell for a second at a time.
Built for the installer
It accepts either AC or DC on the input, so the same part covers both supply types rather than splitting stock. Connections are made through paired white and grey wires, and adhesive for mounting the module is in the box, so it can be fixed neatly inside or beside the chime housing instead of being left loose in the cavity.
The module ships with the ADC-VDB770 itself, so this part number is the replacement or the spare for a module lost, damaged, or needed on a second unit.
