Functional Devices TR75VA004 Transformer As a critical HVAC time

As a critical HVAC time delay relay

using it on low-voltage circuits will result in no illumination

this unit is built with high-grade materials to withstand the thermal stresses of repeated ignition cycles

It is fully compatible with System Sensor legacy duct smoke detector models

Replacing it with a higher temperature limit can lead to cracked heat exchangers or fire hazards

Functional Devices TR75VA004 Transformer As a critical HVAC timeThe Functional Devices TR75VA004 is a versatile 75VA multi tap transformer designed for reliable power stepping in commercial and industrial HVACR control circuits. Featuring a universal primary input of 120 208 240 480 Vac and a 24 Vac secondary output, this unit eliminates the need to carry multiple single voltage transformers on the service truck. The integrated circuit breaker provides essential overcurrent protection, allowing for quick resets
