 Snap-On Load Detector For Low Current Sensing

Snap-On Load Detector For Low Current Sensing

The LD-50 magnetic, snap-on load detector from API Technologies Corp. is for mounting on pre-wired systems that does not disrupt existing connections.  The LD-50 is a high sensitivity current transformer specifically designed for applications where low current is monitored. A primary winding is supplied to increase sensitivity of the transformer.

Available in pre-assembled or unassembled versions, the LD-50 simply snaps over existing wiring.  Ideal for monitoring relays and lamps, hi/low current limits, instrumentation as well as solid state switchgear and motor control, this new load detector is an excellent low cost option for energy management and automation control.

Broadband frequency response of the LD-50 ranges from 30 Hz to 15 kHz.  The easy-to-install transformer measures continuous currents up to 40 A RMS, intermittent currents up to 120 A, and linear output to within 3% of input ranging from 2 A to 20 A.

Technical specifications include:

·     Broadband frequency response from 30 Hz to 15 kHz

·     Measure continuous currents up to 40 A RMS; intermittent currents up to 120 A

·     Linear output to within 3% of input ranging from 2 A to 20 A

·     Operating temperature range from -55 °C to 120 °C
