Voltage Indicator UVN-90M-35-220 SZ IP ELEKTRO TREID UVN137

High voltage indicator UVN-90M-35-220SZ IP is intended to check the presence or absence of voltage on overhead power lines and other AC electrical installations with voltages of 35, 110, 220 kV, frequency of 50 and 60 Hz, at temperatures from – 45°C to + 40°C and relative air humidity not exceeding 98% (at +25°C). The UVN-90M-35-220SZI P indicator is a primary electrical protective device that allows for phase-by-phase voltage determination by touching live parts. The indicator operates without grounding. The operating principle of the indicator is based on converting 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 through its directional propagation. The indicator has a self-test capability for functionality. Reliable operation is achieved by using microchips and components from leading global manufacturers in the indicator's 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 of 7 mA in signaling mode allows the indicator to be used without replacing the battery throughout its entire service life of 10 years. The working part of the indicator is made of ABS plastic, ensuring normal functioning of the electronic elements throughout the entire service life. The insulating part is made of PVC or fiberglass, providing reliable insulation.
