Industrial FTC3716 Industrial Control Transformer

FTC3716 is a 16.5 VAC, 37 VA dry-type control transformer from ATC Frost, engineered to convert 120 VAC, 60 Hz mains to a low-voltage supply for control circuits in security and safety systems. The transformer features a 120 V, 60 Hz primary and a 16.5 V secondary capable of delivering up to 37 VA, and it weighs approximately 0.59 kg, with dry-type construction suitable for mounting inside electrical cabinets. The model is discontinued by the manufacturer, so current availability is typically through distributors or refurbishers rather than new production. In documented security-system configurations, such as DSC TL300 power-supply circuits, the FTC3716 appears as the transformer stage used to supply the low-voltage portion of the system, illustrating its role as a dedicated 16.5 V control transformer for low-voltage electronics. When sourcing a replacement, verify the exact 120 VAC 60 Hz input, 16.5 VAC output, and 37 VA rating to ensure compatibility with your control cabinet and downstream power supplies.
