Description Introducing the TPSR Solid-State Temperature Controllers, a revolutionary solution designed to precisely regulate fan speed in heating, ventilating, and air conditioning systems. Replacing conventional thermostats, the TPSR series employs a thermistor for continuous proportional control of blower speed, responding dynamically to temperature changes. This innovative controller also includes a set minimum fan speed, ensuring gentle air circulation through the heat exchanger and providing motor bearing protection. Key Features: Solid State Reliability: Benefit from robust and reliable performance with solid-state technology, ensuring consistent operation. Epoxy Encapsulated: The TPSR series is epoxy encapsulated, enhancing durability and protecting the controller from external elements for prolonged lifespan. Simple Wiring: Simplify your setup with easy wiring, facilitating hassle-free installation for optimal convenience. Rugged and Compact Design: Built for durability, the TPSR series boasts a rugged and compact design, making it suitable for diverse applications. High Current Capability: Enjoy high current capability, catering to heavy-duty applications with efficiency. Internal Snubber: The internal snubber eliminates “nuisance switching,” contributing to smoother operation and enhanced reliability. Applications: Versatile and suitable for a variety of applications, including: Ovens Fish & Chips Fryers Restaurants Hospitality Industry Quartz Lamps / Heat Lamps Moulder Machines Dryers Some Inductive Loads, e.g., Transformers and Motors Empower your environmental control systems with the TPSR Solid-State Temperature Controllers, offering advanced features for precise and efficient regulation. Upgrade your HVAC systems with this innovative solution for optimal performance and reliability.
