DK772

Panel Meters

A panel meter is an instrument for measuring and displaying the value of a particular electrical value. Panel meters can be used to measure voltage, current, power, frequency, efficiency, and more. The DK772 is a panel meter specifically designed for use in motor control applications.

DK772 Application Field and Working Principle

The DK772 is a digital AC motor current monitor designed for motors of up to 3.5 kW. It can be used in many applications such as machine tools, pumps, water heaters and other small motor control applications. The DK772 has two ranges, 0.4 – 12A and 0.8 – 24A, with a resolution of 0.1A. The accuracy of the meter is 0.3%, which is more than sufficient for the majority of applications.

The working principle of the DK772 is based on a Hall effect current sensor, which produces an output voltage proportional to the measured current. This output voltage is then amplified and converted to a digital signal, which is then used to display the current on the LCD display. There are two push buttons on the meter – one for setting the current range and one for clearing the overload indicator. The overload indicator is a warning signal that indicates when the current is exceeding the safe range.

The DK772 also features reverse power protection and under-voltage protection. These features ensure that the meter will not be damaged if there is a power surge or if the power source drops below the minimum operating voltage. The DK772 is a very robust and reliable panel meter, and is designed to meet the exacting requirements of motor control applications.

Overall, the DK772 is a very useful panel meter for motor control applications. It is easy to install and use, and the accuracy and reliability of the meter make it a great choice for any motor control application. It is an ideal choice for any user who needs an accurate and reliable meter with reverse power and under-voltage protection.
