Panel Meters

Panel meters are instruments that measure the varying electrical quantity in order to display the information in the form of a dial or digital reading. Panel meters are typically used in the fields of electricity, electronics, communication, and instrumentation.

DCA5-20PC-9-DC1-BL-C Application Field and Working Principle

The DCA5-20PC-9-DC1-BL-C is a panel meter that is designed to measure and display the voltage and current in DC circuits. It is primarily used in applications such as automotive, power supply, and home appliance circuits.

The DCA5-20PC-9-DC1-BL-C utilizes a shunt resistor to measure current. The shunt moves current from a higher-level to a lower-level circuit, allowing the current to be measured by the panel meter. This meter is able to measure two channels of current ranging from 0-20A, and it has a two-digit 0.56 inch LED display. The power supply for the meter accepts voltages from 4.5-30V DC, and it has a current consumption of less than 1mA.

The working principle of the DCA5-20PC-9-DC1-BL-C panel meter is simple and can be broken down into two parts. First, when AC voltage or current enters the circuit, it is converted to DC via a rectifier. Then, the current is passed through the shunt resistor, where the current is measured and then sent to the load. The voltage is fed through a voltage divider, which divides the voltage so it can be safely measured by the panel meter. The measured voltage is then displayed on an LED display.

In addition to measuring voltage and current, the DCA5-20PC-9-DC1-BL-C also features other functions, including short circuit protection, over-voltage protection, and reverse-bias protection. Its rugged design also ensures that it can withstand harsh industrial environments and vibrations, making it an ideal choice for a wide range of industrial applications.

The DCA5-20PC-9-DC1-BL-C panel meter is an excellent choice for applications that require precise voltage or current measurement. Its compact design, easy installation, and robust construction make it a great fit for systems where reliability and safety are a must.
