Voltage Indicator UVN-90M-220 SZ IP ELEKTRO TRADE UVN134

High voltage indicator UVN-90M-220SZIPI is designed to check the presence or absence of voltage on overhead power lines and other AC electrical installations with a voltage of 220 kV and a frequency of 50 Hz. UVN-90M-220SZIPI indicator is one of the primary electrical protective equipment. The principle of operation of the indicator is based on the conversion of electrical signals into light and sound signals. The light and sound indication elements of the indicator are located inside a shade, the design of which allows for the amplification of the light and sound signal due to its directional propagation. The indicator has a self-test function for operational integrity before use. Reliable operation of the indicator is achieved by using microchips and components from leading world manufacturers in the electrical circuit, as well as a CR-123 lithium power source with a voltage of 3V and a capacity of 1500 mAh. The low operating current - 7 mA in signaling mode, allows the indicator to be used without replacing the battery throughout its entire service life - 10 years. The working part of the indicator is made of ABS plastic, ensuring the normal functioning of electronic components throughout the entire service life. The insulating part is made of PVC plastic or fiberglass tubes, providing reliable insulation.
