Safety Isolating Transformers

Transformers Now Certified as Safety Isolating Transformers.


Foster Transformer Company announces that five of its transformers have been certified by TUV Rheinland to EN 61558-1 and -2 as Safety Isolating Transformers with SELV (Safety Extra Low Voltage) outputs. Models 15347, 15348-50, 15349, 15349-02, and 15964-02 are also UL/C-UL Recognized for North America.  The 15964-02 is UL / C-UL Recognized to UL 5085-1 and CSA 22.2. All other models are Recognized to UL 5085-3 (formerly UL 1585) and CSA 22.2 No. 66 as Inherently Limited Class 2 transformers. Global safety certifications simplify designing for export. Models 15347 and 15964-02 offer dual inputs of 115 V or 230 V while the 15349 and 15349-02 are designed for nominal 230 V inputs with taps allowing adjustment from 200 V to 240 V, depending on the model.

The 15347 through 15349 models carry 24 V, 75VA output ratings, while the 15964 is rated at 192VA for applications requiring more power. The 15964 also features a 12V output. Each model features auto-resetting thermal protectors that provide short circuit and overload protection eliminating the need for external fusing in most applications.

These transformers are ideal for medical instruments, devices and applications, HVAC and refrigeration, control panels, appliance, vending, battery charger and other applications requiring a low voltage transformer. 

Primary input voltages include 115 V, 115/230 V, 200/230 V, and 220/230/240 V with 24V output. Each size/model includes a UL Recognized Class 130 (B) insulation system with uprated 155 C magnet wire for long life.
