Panel Meters

Panel meters are used to measure a variety of different physical quantities such as electrical current, voltage, power, and energy. They are essential components of any electrical system, such as those found in industrial and commercial facilities. One type of panel meter is the DMS-20LCD-1-5-C.

Application Field

The DMS-20LCD-1-5-C is designed for measuring direct and alternating current between 0 and 20A AC/DC. It is suitable for use in three-phase power systems with up to 400V between phases. This makes it suitable for a broad range of applications, such as in buildings, factories, and shops.The DMS-20LCD-1-5-C is also useful for monitoring parameters in research facilities, laboratories, and even marine environments. It is constructed with durable materials that make it suitable for use under difficult conditions, such as in areas with high levels of vibration or dust.

Working Principle

The DMS-20LCD-1-5-C incorporates a shunt resistor that measures the current flowing in the circuit. This current is then converted into a voltage signal via a current transformer, which is then used to drive a display.To measure AC current, the DMS-20LCD-1-5-C uses a full-wave bridge rectifier to convert the incoming alternating current into a direct current. This is then used to drive the current meter display, which is a four-digit liquid-crystal display (LCD).To measure DC current, the DMS-20LCD-1-5-C uses a Hall effect current sensing circuit. This measures the magnetic fields generated by the flow of electrons and converts them into a voltage signal. This signal is then amplified and sent to the LCD display.The DMS-20LCD-1-5-C also features adjustable overload protection to ensure safety in the event that an excessive current is detected. This can be set up by the user to a level suitable for the specific application.

Conclusion

The DMS-20LCD-1-5-C is a versatile and robust panel meter designed for measuring direct and alternating current between 0 and 20A AC/DC. It is suitable for a broad range of applications, and it is constructed with durable materials to make it suitable for use under difficult conditions. It also features adjustable overload protection to ensure safety.
