The BF2F is a Class 2 energy limiting transformer on a box mount plate, stepping 120V AC down to a 16V AC secondary at a 75 VA power rating. It is intended for electricians, installers and OEM builders powering low-voltage loads such as chimes, door bells, security systems, decorative lighting, furnaces, humidifiers, appliances, vending machines and intercom systems.
A 16 V secondary is a common choice for chimes and door bells, and at 75 VA this unit can supply up to 4.68 A. The design is described as rugged and low noise, and it is for indoor use only. The primary side uses stripped wire leads and the secondary uses screw terminals, so the low-voltage output wiring can be landed without splices.
The transformer is mounted on a box plate for easy installation. Input leads are black and 6 in minimum in length, ready to splice into a 120V branch circuit. The unit is designed for 50/60 Hz operation, with output limited by a built-in circuit breaker. Overall dimensions are 3.00 in (76 mm) A x 2.50 in (64 mm) B x 3.75 in (95 mm) C, and the shipping weight is 3.45 lbs (1.56 kg).
On compliance, the BF2F is c UL us listed under file E184371 as Class 2 (not inherently limited) and CSA certified (209651). It is also REACH and RoHS compliant.
