Radionix D1640 16.5 VAC 40 VA Plug-In System Transformer

Provide low-voltage AC power for compatible physical-security equipment with the Radionix D1640 plug-in system transformer. Its stated output rating is 16.5 VAC at 40 VA, placing it in the common class of AC transformers used where connected system equipment requires transformer-fed alternating current rather than regulated DC power. The plug-in format keeps the transformer at the power outlet while supplying low-voltage power to the connected system. Electrical compatibility depends on matching the equipment’s required AC voltage and apparent-power demand to the transformer rating. A 16.5 VAC output must be appropriate for the receiving device, and the combined connected load must remain within the 40 VA rating. This matters particularly where one transformer powers equipment with continuous standby load as well as intermittent operating load. D1640 is specified as a system transformer, making the 16.5 VAC and 40 VA ratings the primary selection details. It is not described as a DC adapter, battery charger, enclosure power supply, or multi-output distribution unit. Verify the required input type, voltage, load rating, connector method, and installation arrangement of the equipment being powered before selecting this transformer. The plug-in construction provides a direct option for applications that call for a separately mounted AC transformer at the outlet.
