Product introduction
HF-ZK switch cabinet intelligent control device 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.
Superior characteristics
● With highly-integrated CPU and internal electronic components from world-class manufacturers, the device has high operation stability.
● In case of single-phase grounding or phase loss and other abnormal conditions, the device can still keep the locking 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 2-channel heater and 2-channel fan, which can realize automatic control of the measured ambient temperature and humidity.
● The device has the function of voice prompt, which can effectively prevent incorrect manipulation.
● The device can be adapted to a variety of change-over switches to meet the needs of various switch cabinets.
