Panel and DIN Rail Temperature Controller

The Panel and DIN Rail Temperature Controller from Zhejiang Chenhai Electric is a versatile device designed to maintain optimal temperature in electrical enclosures, industrial machinery, and HVAC systems. It operates on AC 220V power supply and supports two convenient mounting methods: panel mounting for front‑of‑panel access, and DIN rail mounting for quick installation inside distribution boxes. This flexibility makes it suitable for both new builds and retrofits. The controller uses a built‑in temperature sensor or accepts external probe inputs (optional) to measure ambient conditions accurately. It features a digital display with adjustable set points and hysteresis, ensuring stable control without frequent relay cycling. When temperature falls below the low set point, the integrated relay activates a heating element to prevent condensation and freezing. When temperature exceeds the high set point, the relay switches on a cooling fan or air conditioner to avoid overheating. This d…
