Neilsen Kuljian

The newly re-designed ASM Series is more accurate and easier to use than previous models. This Self Calibrating Smart-Switch uses the actual load current to set the trip point.

It takes just a couple of seconds of steady running conditions before the sensor locks onto the normal current level.

ASM Series Self-Calibrating Smart-Switch

Operating Instructions

Upon sensing an average operating current, the ASM self-learns and establishes a limit-alarm trip point based on 85-125% of normal current (overload/underload model only). This sensor eliminates the need to adjust the sensor trip point manually, which means no screwdriver inside an energized control panel. Helps with NFPA70E compliance.

Red Lion Counters

As a Counter/Rate Instrument, the rate indicator will utilize the same count signal input as the counter except when in "Separate Input" mode, where the rate channel will use one input and the counter channel the other. As a dual counter instrument, both counters will utilize the signal inputs in the same manner. In other words, in all modes except the "Separate Input" mode, a count pulse applied to the input will affect both

SymCom PumpSaver

A Unique Microcontroller-Based voltage and current-sensing algorithm constantly monitors the incoming power for fluctuations. When an abnormality, such as a loss of load is detected, the PumpSaver Plus deactivates its output relay directly disconnecting the pump motor. SymCom's Model 231-Insider-P single-phase PumpSaver Plus fits inside 1/3, 1/2, 3/4, and 1hp 230V control boxes and is designed to
