DXN display with side outgoing ling
This product is used to provide a switchgear equipment circuit voltage information at the installation status to the operator. As a result of its internal circuitry of low-power light-emitting element, which makes low power consumption, more stable performance and higher reliability. For the user test double-loop phase conveniently, indicator(recommend type) panel setting the end of the test phase, meanwhile the frame of indicator (recommend type) shell adopts front end removable. And the user can change the indicator without opening the indicator shell.
Widely used for indooe 7.2,12,24,40.5kV, frequency of 50Hz high voltage electrical equipment, and supporting the use of the voltage sensor, it can reflect the high voltage live situation, and voltage sensor support, but also to improve the anti-error performance ancillary products.
