Panel Meters are designed to provide clear visual indication of various parameters. They are used for both office and industrial applications, for monitoring or controlling a process. One of the most well-known panel meters is the DK809ACA. Here we will review its application fields and working principle.

Application field

The DK809ACA is an easy-to-use DC voltage panel meter widely applied in auto and motorcycle, LED/LCD displays and other applications. It measures DC voltage up to 30V with a resolution of 0.1V. Its features include wipe-clean plastic lens, no rivet design, modern style, easy mounting, low current consumption and glare-free display.

This meter is also designed to be vibration-resistant and can operate at temperatures between 0 and 100°C. As such, it is suitable for use in commercial vehicles, marine and harsh environments. It is also RoHS compliant.

Working principle

The working principle of the DK809ACA is as follows. The panel meter is powered by DC voltage and provides an output of connected load. The mounted active rectifier circuit converts alternating current (AC) to direct current (DC). Output voltage is measured and compared with a reference. This reference is set by scanningelectrically connected resistors.

The transistor output circuit of the DK809ACA is designed to ensure accuracy and to protect the panel meter from voltage spikes and noise. When the measured voltage drops below or rises above the reference voltage, the indicator light can be used to display the voltage status. The digital display can also be used to indicate the resistance value for easy readability.

The DK809ACA panel meter is a reliable and versatile measuring tool. Its application fields cover many industrial and household applications, including automotive, motor vehicles, home appliances, and LED/LCD displays. Its accurate and reliable measuring performance makes it one of the most widely used panel meters.
