Dual power source
Provides power supply to the motor operator by using two lines. The device has two inputs, from line I (LN I)
and line II (LN II), and one output for the motor operator. The motor operator is automatically energized
whenever power is available in one of the lines. Can be used with 230VAC motor operators. Snap-on mounted
PCB connectors are included in the delivery. The device can be DIN-rail or screw mounted.

Dual power source including ATS functionality
Similar to previous dual power source but also including ATS (Automatic Transfer Switch) functionality and in-
built short-circuit protection. Provides power supply to the motor operator by using two 220...240 V AC lines.
Motor operator is automatically energized whenever power is available in one of the lines. The device has a
three position (AUTO-MAN-O) DIP switch to choose the correct operating mode. The AUTO position enables
and the MAN position disables the ATS functionality when used with OTM motorized change-over switch. The O
position is used for safety reasons: it operates the OTM to position 0 to isolate the load from the feeding
sources. The device can be DIN-rail or screw mounted.
