500V AC LED Voltmeter + 100A Ammeter + Frequency Meter, Yellow

Yellow LED indicator 22mm square voltmeter up to 500V, current meter up to 100A, frequency meter up to 75Hz

Indicator screwed into a standard 22mm hole in the form of an AC ammeter / voltmeter / frequency meter built into the front of the indicator. The color of the light is matched to the color of the indicator. Power supply with alternating voltage in the range of 60V to 500V max, is connected with wires directly to the X1 and X2 twisted terminals in the lower part of the indicator.

The current consumption is non-invasive and without breaking the electric circuit for the duration of the measurement. One conductor, e.g. the phase L conductor, is enough to lead through the center of the measuring coil for the meter to display the value of the current flowing through this conductor. 2 wires (phase with neutral) cannot be passed through the coil because the current will be 0A. The meter is designed to measure high currents up to 100A.

The lamp can also be used to measure low voltage current in a transformer rectifier to charge the batteries. The connection would have to be as follows:

Power supply of X1-X2 control should be connected to 230V AC mains voltage on the primary side of the transformer. Pass 1 wire of the cable from the transformer to the bridge rectifier through the opening of the coil, the other wire must pass the coil.
