Introduction

DMS-20PC-2-RL-C are panel meters that are used to measure the electrical current and AC line voltage working in an AC circuit. The DMS-20PC-2-RL-C panel meters offer a wide range of features including a built-in voltage detection circuit, adjustable voltage range, a switching output, and a voltage meter display. The DMS-20PC-2-RL-C panel meters are designed for easy installation and can be mounted on any type of electrical panel.

Application Fields

DMS-20PC-2-RL-C panel meters are used in a number of applications such as industrial, commercial, and residential applications. The panel meters are a reliable and accurate way to monitor and control the AC line voltage in a system. The large display provides a clear and easy-to-read indication of the current power level. The adjustable voltage range means that the device can be set for any number of voltage levels that are needed in the application.

Working Principle

The working principle of DMS-20PC-2-RL-C panel meters is based on a DC voltage detection circuit. The voltage detection circuit has a rectifier diode connected to the output of the AC line voltage and a zener diode connected to the ground. As the AC line voltage rises, the rectifier diode will draw current and the zener diode will conduct electricity as well. This will cause a voltage drop across the rectifier diode which will be sensed by the voltage detection circuit. The voltage detection circuit then sends the signal to the meter\'s display, which will indicate the AC line voltage.The DMS-20PC-2-RL-C panel meters also have a number of safety features built-in. One of these features, the "overvoltage" feature, will shut the meter off whenever the AC line voltage goes above a certain level. This ensures that the system does not potentially overload the circuit.

Conclusion

The DMS-20PC-2-RL-C panel meters are reliable and accurate devices used to measure AC line voltage. The panel meters offer a wide range of features such as a built-in voltage detection circuit, adjustable voltage range, and a switching output. The panel meters also have a number of safety features to protect the system from potential overloads. The DMS-20PC-2-RL-C panel meters are a great choice for any application that needs to monitor and control AC line voltage.
