Hammond BPD2G 24V 20VA Class 2 Plug-In Transformer, 120V Input

The BPD2G is a Class 2 energy limiting plug-in transformer that converts 120V AC to 24V AC at 20 VA, delivering up to 0.83 A. It is aimed at installers and OEM builders powering AC chimes, door bells, security systems, decorative lighting, furnaces, humidifiers, appliances, vending machines and intercom systems from a standard receptacle.

The 24 V output is the highest in the BP range and suits 24 VAC controls and security panels. The transformer is enclosed in a black plastic plug-in case, and the secondary connects through 2 recessed slot head screw terminals on the plug side. As a 20 VA unit it is inherently limited, so it has no fuses or circuit breakers.

The BPD2G is rated for 60 Hz and for indoor use only. It is CSA certified (#LR 113601) and UL listed (#E 184936), and is REACH and RoHS compliant. Shipping weight is 1.1 lbs (0.50 kg).

Every model in the BP Series takes a 120V input: the 20 VA models carry the BPD2 prefix and the 40 VA models the BPE2 prefix, and each group is offered with 12, 14, 16, 18 or 24V outputs. If your 24V load needs more than 0.83 A, the 40 VA BPE2G doubles the power rating at the same output voltage, at the cost of a fused rather than inherently limited design.
