1. Key models

KS-3-4S, KS-3-4T2, KS-2BKX, KS-1C, KHS-3-4T2, WSK-C, and WSK-TLD etc.

2. Product overview

This series of products is an environmental control device for power equipment based on analog circuit design. It can be used to automatically adjust the environment inside the cabinet by real-time monitoring of high temperature, low temperature and over-humidity conditions inside the cabinet, and has multiple protection measures to effectively prevent component failure caused by excessively high or low temperatures inside the cabinet, or accidents such as creepage and flashover caused by excessive humidity.

3. Functions & features

·Analog design, intuitive display, easy to operate

Adopting analog circuit control, simple structure, stable operation, suitable for long-term use.

Equipped with a mechanical temperature and humidity dial or display light to visually display the current ambient temperature and humidity.

Users can manually set the temperature and humidity thresholds, which is simple and easy to operate.

·Precise monitoring and intelligent control

High-precision sensor (temperature of ±2°C, humidity of ±5%RH), covering range: -20°C ~ +55°C.

Automatically start and stop loads (heaters/fans), supporting multi-mode switching of heating, dehumidification and cooling.

• Safety and protection

Flame-retardant enclosure: V0 rated

Triple-protection design: fungus proof, moisture resistant & salt spray protected

Alarm system: threshold alert & real-time anomaly warning

·Simplified installation

Support panel and DIN- rail installation, adaptable to different cabinet structures.

-Energy saving and environmental protection

It adopts low power consumption design, energy saving and environmental protection, and long-term use can effectively reduce energy consumption.
