ACI A/ASCS Series Split-Core Adjustable Current “Status” Switches

Split-Core Adjustable Current “Status” Switches
A/ASCS Series

The A/ASCS and A/ASCSX series current switches are available in a split-core with either Normally-Open (N/O) or Normally-Closed (N/C) output configurations. All of these sensors will have a solid-state output with an adjustable trip point (setpoint). These current switches are ideal for providing status information on any type of AC current using equipment.

These current switches should be used in applications in which a current switch with adjustable trip point is required. A change in the operating current may indicate motor failure, belt loss/slippage, or mechanical failure. Any time one of these events occurs, the current can significantly increase or decrease, thus tripping the sensor, and notifying the Building Management System of an alarm condition.

The A/ASCS and A/ASCSX series current switches can be used to monitor devices with a maximum continuous operating current of 200 to 250 Amps depending on the model. These current switches will not need to be externally powered, since the power for the switch is induced from the conductor being monitored. Another great feature of the A/ASCS and A/ASCSX series current switches is that they include a Red and Green LED that will indicate the “Status” of the switch contacts.
