HF-ZS switch cabinet status indicator

HF-ZK switch cabinet status indicator is mainly used in a variety of 3-35KV indoor switch cabinet. 

This product visually displays the primary simulation diagram and switch state, beautifies the panel structure, simplifies the field wiring, and improves the safety performance.

● With highly-integrated CPU and internal electronic components from world-class manufacturers, the device has high operation stability. 

● In case of single-phase ground or phase loss and other abnormal conditions, the device can still keep the blocking voltage unchanged, which effectively guarantees the safety. 

● For the collection of temperature and humidity data, a high-precision sensor is used to ensure the high accuracy and reliability of data collected. 

● The device can be equipped with 1-channel heater and 1-channel fan, which can realize automatic control of the measured ambient temperature and humidity. 

● The product is characterized by small size, easy installation, good environmental tolerance and electromagnetic compatibility. 

● It shall be used indoors, with altitude: ≤3,000m, ambient temperature: 25℃ - 85℃, relative humidity: ≤95%, atmospheric pressure: 80 - 110kPa.

● The phase of the input voltage shall be carefully checked during field wiring; otherwise, the electrified indication part will display errors.

● After ordering, the primary wiring diagram and voltage level, and the length of the lead cable of the temperature and humidity sensor of the switch cabinet shall be provided.

● The input end of the high-voltage electrified indication circuit shall be connected to the high-voltage bus through the special high-voltage electrified sensor, and shall not be directly connected to the high voltage.
