AS1 Series

Operating Instructions

With its tiny 1 inch housing, the AS1 is a compact and cost-effective solution that enables users to monitor an energized circuit in tight spaces.

The easy-to-use ring design easily slips onto a conductor to reliably detect currents as low as 0.5A with a single conductor pass, eliminating the need to wrap conductors multiple times. Reliable, solid-state output with no moving parts provides a nearly unlimited number of operations.

The AS1 Series-CC current sensing switch is a powerfully simple solution to complicated control requirements.

When a user needs to know that a circuit is energized but they don't want to cut into the insulation or add burden to the monitored circuit, a current operated switch is the best solution.

And when the primary circuit draw is less than 50 amps, a small, well-insulated device such as the AS1 is just what is needed.

Current Sensing Switch Applications

  • Quick reporting of electric motor load status.
  • Identify open heater circuit connection.
  • Independent verification that the load is energized.
  • Confirmation of operation for critical lighting or equipment.

The AS1 has 24 inch leads that can be connected directly to controller input terminals or brought out to a terminal block to facilitate remote operation. The contact can control either AC or DC circuits to 120 volts, with a maximum load capacity of 150mA. There is near zero off-state leakage providing positive indication of the presence of AC current, and the output easily handles the coil of an industrial quality relay.

Current Sensing Switch Features

  • Low Sensitivity Turn-On Point - Detect currents as low as 0.5 A with a single conductor pass, eliminates the need to wrap conductors multiple times to increase sensitivity.
  • Reliable Solid-state Output - No moving parts provide a nearly unlimited number of operations, and powered from the monitored circuit.
  • Choice of Outputs - Normally Open or Normally Closed connection. Connect the leads 24" long leads to a local controller or to a terminal block for remote operation.

This current sensing switch is powered directly from the monitored circuit to monitor and report electric motor load status, identify open heater circuit connections and independently verify that a load is energized. It is also useful for confirming current flow to and operation of critical lighting and other equipment such as fans, heaters, pumps or other AC powered devices. The AS1 is rated for use in ambient temperatures ranging from -4 to 122 degrees F (-20 to 50 degrees C).
