Air Products and Controls Enclosed 24 VAC Power Sources


The Air Products and Controls T-PB Series power source provides 24 VAC from a 115 VAC input. Each T-PB Series unit contains an LED that illuminates when the 24 VAC output is operational. An on/off switch is provided in the 115 VAC input. This switch disconnects or connects both the hot and neutral of the input power. A convenience outlet is located on the front panel. This convenience outlet is not controlled by the on/off switch and is always hot. A circuit breaker is incorporated in the 24 VAC circuit, which must be manually reset if the rated 3.0A (Class 2) or 4.0A (Class 1) is exceeded and the breaker operates.The T-PB Series is available in a metal enclosure (UL Listed) for field applications or without the enclosure (UL Recognized) for panel mounting.
