Hammond BPE2G 24V 40VA Class 2 Plug-In Transformer, 120V Input

The BPE2G is a Class 2 energy limiting plug-in transformer that converts 120V AC to 24V AC at 40 VA, delivering up to 1.67 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 40 VA unit it is protected by an internal slow blow fuse; the part drawing identifies this as a built-in 2.0A slow blow fuse and warns not to short the output.

The BPE2G 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 1.75 lbs (0.79 kg). The drawing label shows model F5-AC2440VA-2S, input 120V 60Hz 60W, output 24V 40VA, marked Made in Taiwan, with cautions to keep the unit away from liquid, vapour or rain.

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 draws less current and you prefer an inherently limited design with no fuse, the 20 VA BPD2G offers the same output voltage.
