Introduction

Panel meters are perhaps one of the most widely used measurement tools across a variety of industries. They are used in a variety of applications, ranging from industrial process control applications to electric utility metering applications. The DLA20-ACA5-4-AC1-R panel meter is one of the most popular panel meters for the industrial market. In this article, we will discuss the application field and working principle of this device.

Application Field

The DLA20-ACA5-4-AC1-R panel meter is used for single phase electric power metering and control applications. It is especially suitable for use in facilities where legacy analog meters are still in use and need to be replaced or where the cost of installation of an advanced digital panel meter would be prohibitive. The device is suitable for a wide variety of applications ranging from industrial process control, to electric utility metering, to building automation. The DLA20-ACA5-4-AC1-R panel meter measures and displays voltage, current, frequency, power, energy, and other parameters related to electric power. It offers a wide variety of features, such as automatic power-off, over-current protection, user programmable alarm thresholds, and a digital display with LED indicators. The device also offers a variety of protection functions, including over-voltage, over-current, and under-voltage protection.

Working Principle

The DLA20-ACA5-4-AC1-R panel meter uses a direct current sensing circuit to detect and measure AC power. The current sensing circuit comprises a transformer, current sensor, and IC amplifier. When an AC voltage is applied to the current sensor, it is transformed into a differential voltage and current across the secondary of the transformer. The differential voltage is amplified by the IC amplifier and then sent to the display unit. The display unit then processes the signal to determine the various power parameters—such as voltage, current, frequency, and power—and displays the results on the LED display.The DLA20-ACA5-4-AC1-R panel meter also features an analog output port that can be connected to an external record keeping system, such as an HMI, PLC, or other digital device. This allows for data logging and analysis, as well as monitoring in-depth variables such as power quality, energy usage, and load profiles.

Conclusion

The DLA20-ACA5-4-AC1-R panel meter is an advanced digital panel meter that is suitable for a wide variety of electric power metering and control applications. It offers a wide array of features, including current sensing, over-voltage and over-current protection, user programmable alarm thresholds, a digital display with LED indicators, and an analog output port. Its direct current sensing technology makes it an ideal solution for facilities that need to replace or upgrade their legacy analog meters.
