SK3118 Electronic Hygrostat for Cabinet Climate Control
Key Specifications
SK3118 electronic hygrostat is a DIN‑rail mounted humidity controller with wide voltage input and precise humidity sensing. Equipped with an intuitive rotary setting knob with visible humidity scale, it accurately detects relative humidity and activates heaters, fans or dehumidifiers automatically to achieve moisture‑proof and dehumidification inside enclosures.
Built‑in passive dry contact supports frost protection. When the ambient temperature drops below 4℃, the contact switches on to prevent freezing damage for electrical cabinets. It adopts UL94V‑0 flame‑retardant plastic housing, compact dimension and easy installation on standard 35 mm DIN rail. With ±3%RH low switching differential, stable performance and 3‑year warranty, it has CE & RoHS certification, widely used in electrical cabinets, control boxes and industrial enclosures.
