Product Description
United Automation TPSR-25 is a variable AC voltage regulator modular power controller designed to control AC loads up to 6 kW with a rated average on-state current of 25 A and a surge current rating of 250 A. It features a full wave AC phase-angle control mechanism that provides variable phase-controlled output based on a potentiometer wired across specific terminals.
This controller is equipped with a thermistor option enabling proportional control of blower speed in response to temperature changes, making it ideal for regulating fan speeds in heating, ventilation, and air-conditioning (HVAC) systems.
The device ensures low thermal impedance and high electrical isolation, operating reliably at load currents as low as 100mA. It meets I.E.T. Regulations (BS7671) and is designed for industrial and HVAC automation applications requiring precise power control.
Users are advised to use a plastic housed potentiometer with a plastic shaft for optimal performance. The unit is suited for industrial automation and power management systems where AC voltage regulation is critical.
Full wave AC phase-angle control for precise load regulation up to 6 kW. Thermistor option for temperature responsive blower speed control. Low thermal impedance and high isolation for durability and safety. Operates effectively down to 100mA load current levels.
Compliance with I.E.T. Regulations (BS7671) safety standards. Recommended use with plastic potentiometers with plastic shafts. Operational temperature range from 0°C to 65°C for versatile industrial applications. Country of origin: United Kingdom.
