Panel Meters

Panel meters measure and display a variety of electrical parameters. They are typically used to measure and display the voltage, current, frequency, power, and power factor of a particular system or circuit. Panel meters are available in a variety of sizes and styles, and are used in various industrial and commercial applications, such as machine control, instrumentation, and power distribution systems.

K3MA-L 100-240VAC Application Field and Working Principle

The K3MA-L 100-240VAC is a five-digit, digital panel-mount meter designed to measure and display AC voltage up to 240V in three ranges. It is ideal for low-cost requirements for measuring and displaying alternating current voltages in single-phase circuits and up to 480V three-phase circuits. This instrument also features a comprehensive alarm system and a bright, LED display with a 0.56” character size.

The meter is based on a Hall-effect input device that uses fluxgate technology for AC voltage measurement up to 240V. This technique provides high precision and fast response time of 10 ms or less. The meter has an overall accuracy of 0.2%, with a maximum reading of 6200 counts. The direct connection of the Hall-effect input device to the three winding of the phase line guarantees the same readings on all three ranges.

The K3MA-L 100-240VAC is designed to monitor single-phase input voltage with a maximum voltage rating of 240V. It also features two adjustable high-limit alarms with red LED indication. The alarm limits are set up by a separate adjustable voltage source or by a selector switch. The standard temperature range is 5 to 40°C, and the meter is available in either panel-mount (flange-mount) or DIN-mount configurations. The meter is also enclosed in a NEMA 4/IP20-rated housing for protection against dust and water.

The K3MA-L 100-240VAC is ideal for monitoring power supply and motor control in industrial environments. It is also used for controlling lights, fans, pumps, and other machinery in the home, as well as in commercial buildings. The meter is also suitable for use in educational and scientific laboratories.

In summary, the K3MA-L 100-240VAC is a high-quality, digital panel-mount meter designed to accurately measure and display AC voltage up to 240V. The meter is designed with a wide range of input voltage range and adjustable high limit alarms, and contains a NEMA 4/IP20-rated housing for protection against dust and water. Additionally, the meter can be used in various industrial, laboratory, home, and commercial applications.
