ECSH41AD

ECSH41AD is a current and voltage relay output monitoring and alarm device. It is mainly used for the monitoring of various electrical equipment, such as motor protection, AC contactors, DC contactors, switching controllers, etc., to monitor and alarm of current and voltage, over and under overvoltage, over and undercurrent.

Working Principle:

ECSH41AD consists of a high-precision rectifier bridge, a shunt resistor, and a sensor circuit. The high-precision rectifier bridge is used to convert the AC signal to the DC signal, and the shunt resistor is used to convert the current signal to a voltage signal. The sensor circuit is used to measure the voltage and current signals and output a voltage or current signal. When the measured value reaches or exceeds the set threshold, the sensor circuit sends a signal to the relay circuit to switch the relay to the second state, starting the alarm signal.

Application Field:

ECSH41AD is widely used in various electrical equipment to detect over and under voltage, over and under current signals and alarms. Its main application fields are:

1. Motor protection:

ECSH41AD can be used to monitor the current, voltage and other parameters of the motor, to detect the overcurrent, overvoltage and other parameters of the motor, and to output an alarm signal when the value exceeds the set threshold.

2. AC contactors:

ECSH41AD can be used to monitor the AC contactors, detect the overvoltage and other parameters of the AC contactors, and output an alarm signal when the value exceeds the set threshold.

3. DC contactors:

ECSH41AD can be used to monitor the DC contactors, detect the overvoltage and other parameters of the DC contactors, and output an alarm signal when the value exceeds the set threshold.

4. Switching controllers:

ECSH41AD can be used to monitor the switching controller, detect the overvoltage and other parameters of the switching controller, and output an alarm signal when the value exceeds the set threshold.

Advantages:

1. High accuracy, fast response, reliable performance.2.Simple structure, easy installation, convenient maintenance; 3.Wide application range, can be used in various electrical equipment.In conclusion, ECSH41AD is an ideal choice for current and voltage relay output monitoring and alarm device due to its high accuracy, fast response and reliable performance. It is widely used for motor protection, AC and DC contactors, switching controllers and other electrical equipment, and can effectively monitor and alarm the over and under voltage, over and under current signals.
