ABB 1SVR730760R0500 CM-SFS.22S CURRENT MONITORING RELAY

Designed for general-purpose magnetic field measurement, current sensing, and position sensing.

Current sensing relay for monitoring electrical current.
Current carrying wire is routed through an aperture.
Electrical isolation between circuits (SPDT).
Internal transformer for scaling the current and a voltage reference circuit for a repeatable trip point.
UL Recognized for safety and RoHS compliant for hazardous substances.

Power – 500 Watts Max x 2 @2-Ohms, 250 Watts Max x 2 @4-Ohms, 1000 Watts Max x 1 Bridged @4 Ohms.
Full Range – With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers.
Class A/B Topology – Class ‘A’ amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class ‘B’ amplifiers have no current flowing through its outputs with no audio signal.
Mosfet Power Supply – A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry.
Variable Gain Control – The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier.

Spanish/English Bilingual - Easy to replace module containing current CPR guidelines and two languages..
Clear confident voice prompts. Also CPR prompts to help the student keep pace with chest compressions.
Made in the USA. Now with a Three Year Warranty.
Prestan Pad Sensing System - Detects Pad Placement - unique Pad Sensing System automatically detects when each pad is placed on the manikin which simulates a live AED allowing for a more realistic training class..
Quality pads that last. High quality training pads that will last a long time with a minimum of 50-60 applications.

High precision, more stable and long service life.
It is an ideal choice for automated industrial equipment and store monitoring..
This AC current sensing switch is designed and manufactured to solve the AC current monitoring. It uses the principle of mutual inductance to sense the AC current through the AC, isolate the AC current, and output a normally closed switching signal to di.
Widely used in substation, frequency conversion speed control device, inverter device, electrolytic plating, electric locomotive, street lamp monitoring, coal mine and other automation industries requiring current monitoring.
