ACI A/ACS Series Solid-Core Adjustable Current “Status” Switches

Solid-Core Adjustable Current “Status” Switches
A/ACS Series

The A/ACS and A/ACSX series current switches are available in a solid-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 where a current switch with an 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/ACS and A/ACSX series current switches can be used to monitor devices with a maximum continuous operating current of up to 250 Amps. 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/ACS and A/ACSX series current switches is that they include a Red and Green LED that will indicate the “Status” of the switch contacts.

• Red and Green status LED’s
• Integral Din-rail mounting flange
• Rated up to 250 Amps
• Limited 5 year warranty
• UL94-5VB (enclosure rating) Applications:
• Monitoring overloads, underloads and normal operating conditions
• Monitoring belt loss or slippage
• Monitoring Filter Status
• Rated for industrial use
