Voltage

Warner Electric’s One Shot Power Supply
provides a single overexcite voltage pulse when
the switch is momentarily closed, or held
closed, and is designed to be used with all
12VDC, 24VDC, 90VDC and 115VAC D-frame
solenoid operated Wrap Spring products that
contain an Actuator Limit Stop option.

Installation and Operation

Mounting

The Unit may be mounted in any position
through the use of the two mounting holes and
8 - 32 screws (See figure 2 for unit dimensions).

Wiring

The one shot must be wired as shown in Figure
3, otherwise the control will not function
properly.

1. Wire AC line voltage through fuse to yellow
connector as shown.

2. Wire solenoid coil to green connector as
shown.

3. Wire switching circuit (relay contacts) to
white, red and black connectors as shown.

When the switch/relay is actuated, the solenoid
coil is energized by the pulse from the internal
capacitor discharging. When the switch/relay is
released or deactivated the internal capacitor is
charged for the next cycle. The minimum time
between operations is 15 milliseconds.
