L-com’s new sensors are reported to protect against over-current, short circuits, inefficient energy usage

February 28, 2023

IRVINE, Calif.—L-com, an Infinite Electronics brand and a supplier of wired and wireless connectivity products, has expanded its line of AC and DC current sensors, the company said in a release.

The new AC and DC sensors are suitable for IoT applications and are said to protect electrical systems from over-current, short circuits, and inefficient and costly energy usage. The devices are designed for use in building and facility management systems, including HVAC, electric fans, electric pumps, and electric motors, as well as industrial automation and machine building applications.

The AC current sensors and over-current protectors are offered in various detection ranges from 5 amps to 100 amps. They have analog and relay outputs, and some have an RS485 output. Some versions have an output delay timer, the company said.

Available choices for DC supplies include 5 volts, 12 volts, and 24 volts. They use current transformer (CT) technology. Two of the AC current sensors are available with 10 input channels and monitor all 10 simultaneously, according to the release.

The DC current sensors and over-current protectors are offered in various detection ranges from 1 amp to 70 amps. They have analog (0 to 5 volts) and relay outputs and adjustable threshold levels. Some versions are available with a display, and selected models have an external shunt resistor that activates a relay if the current exceeds a preset value, the company said.

Both the AC current sensors and the DC current sensors have compact sizes and low power consumption. They feature screw-type terminal blocks for easy field termination, and a removable PCB for a panel or other enclosure. They mount to a standard 35-millimeter DIN rail, a wall or a panel.

“These new AC and DC current sensors not only give our customers insight into how their electrical systems are operating, but protect their systems from over-current and short circuits and improve their energy efficiency,” said L-com Senior Product Line Manager Tim Houghton, in the release.

L-com is headquartered in North Andover, Massachusetts, and is ISO 9001:2015 certified. The company offers a wide range of components for the electronics and data communications industries, including cable assemblies, connectors, adapters, antennas, enclosures, and surge protectors.
