WSK-ZD/ZG Temperature and humidity controller

Product Introduction

Product Overview & Core Application Orientation

The WSK-ZD/ZG series are high‑performance, panel‑mount temperature and humidity controllers designed for stable environmental regulation in electrical cabinets, power distribution rooms, switching stations, terminal boxes, and other enclosed equipment spaces. Built to solve common problems like condensation, overheating, excessive dryness, and component aging caused by unstable temperature and humidity, these controllers integrate high‑precision sensing, real‑time monitoring, intelligent logic control, and automatic adjustment functions in one compact unit. Unlike basic single‑function indicators, the WSK‑ZD/ZG series can automatically start heating, cooling, fan, or dehumidification equipment according to user‑set thresholds, creating a safe and stable operating environment for electrical and electronic systems. As a mature product from Suosite Electrical, a professional manufacturer of industrial control instruments and relays with more than 10 years of R&D and manufacturing experience, the WSK‑ZD/ZG series follows strict industrial design standards, supports long‑term uninterrupted operation, and has been widely used in power, communications, manufacturing, and infrastructure industries worldwide. Whether used for new equipment matching or retrofitting existing cabinets, these controllers provide reliable automatic environmental control, reduce manual inspection workload, and effectively extend the service life of internal components.

Key Product Features

The WSK-ZD/ZG temperature and humidity controllers come with a full set of practical features tailored for industrial and power scenarios, making them easy to use, stable, and highly compatible. First, they support dual‑parameter simultaneous monitoring and control, accurately collecting temperature and humidity signals in real time without mutual interference, ensuring users can grasp environmental changes comprehensively. Second, the controllers adopt a high‑definition LED digital display, with clear digits and high contrast, allowing users to quickly read current values and set parameters even in low‑light cabinet environments. Third, they feature wide range adjustable thresholds, with flexible temperature and humidity setting ranges to meet different application requirements; users can easily modify upper and lower limits via panel buttons to match specific working conditions. Fourth, the product provides multiple control output modes, supporting direct drive of heaters, fans, dehumidifiers, and other auxiliary equipment, with strong load capacity and stable action. Fifth, the controllers have power‑off memory function, automatically saving all set parameters; after power restoration, they can resume working without reconfiguration, avoiding abnormal environment caused by sudden power failure. Sixth, they adopt a standard panel installation structure, with uniform size and simple wiring, suitable for various electrical cabinets and control boxes, greatly reducing installation and commissioning time. In addition, the shell is made of high‑strength flame‑retardant material, with good heat resistance and insulation performance, improving operational safety.

Technical Advantages & Reliability Performance

With the technical accumulation and production experience of Suosite Electrical in industrial automation instruments, the WSK-ZD/ZG series shows outstanding technical advantages and long‑term reliability in actual operation. The core advantage lies in its high‑precision sensing system, using industrial‑grade temperature and humidity sensors with fast response speed, small drift, and long‑term stability, ensuring measurement accuracy is maintained for a long time even in harsh environments. The control circuit adopts an optimized microprocessor design, with fast operation speed and high anti‑interference ability, which can work stably under complex electromagnetic interference such as high‑voltage equipment starting and power line fluctuation. In terms of control strategy, the instrument uses intelligent logic judgment, avoiding frequent start‑stop of loads caused by slight signal fluctuations, reducing equipment wear and extending service life. The whole machine has undergone strict aging tests and insulation tests, with high and low temperature resistance, moisture resistance, and shock resistance, fully adapting to the harsh environment of outdoor cabinets, unattended stations, and industrial workshops. In addition, the product has complete safety protection design, including overcurrent protection, reverse connection protection, etc., to ensure that the controller itself and the connected load equipment are not damaged. Compared with similar products on the market, the WSK‑ZD/ZG series has higher cost performance, more stable performance, and lower failure rate, and has been verified by a large number of long‑term applications.

Function

The main function of the intelligent controller is to start the load operation according to the user's Settings.

Working principle: These are all conditional triggers. For example, when the temperature is 5 degrees, then the controller initiates the heating load.

When the temperature reaches 10 degrees, the controller stops the load heating.

When the humidity reaches 68%, the controller initiates dehumidification.

When the humidity drops to around 81%, the controller stops working under load (the temperature and humidity values are set by the user themselves).

It can be set to the heating function and connected to heating equipment, etc., and can also be set to the cooling function and connected to cooling equipment, etc.

It can be set to the humidification function and connected to a humidification device, etc., and can also be set to the dehumidification function and connected to a dehumidification device, etc.
