Frequency meter 45-65Hz

An analog panel frequency meter, also known as a frequency meter or frequency gauge, is an electrical instrument used to measure the frequency of an alternating current AC signal. It provides a visual representation of frequency on an analog display, typically using a pointer or needle moving across a calibrated scale. They are designed for panel or enclosure mounting and are often used in control panels or electrical cabinets. The panel are with dimesnion 72x72. Analog frequency meters are typically connected in parallel with the circuit or components carrying the AC signal. The signals frequency causes the needle on the scale to deflect. Possibility for voltage 110V, 230V , 400V\nNote: MEMSI - magnetic-electrical movable steel instrument, \nMEMC - magnetic-electrical movable coil
