Nov. 12, 2015 – Foster Transformer says its line of Safety Extra Low Voltage (SELV) safety isolating transformers are certified to EN 61558-1, EN 61558-2-6, and the latest edition of EN 60335-1.

Many models are also UL and C-UL Recognized as Inherently Limited Class 2 transformers under UL 5085-1, UL 5085-3, CSA C22.2 No. 66.1-06, and CSA C22.2 No. 66.3-06, it adds. In addition to providing isolation for the connected load, these transformers are capable of withstanding a direct short-circuit in excess of 15 days, and require no external fusing, notes Foster. Transformers are glow-wire compliant per EN 60335-1 for appliance applications, and are offered with output ratings of 75 VA and 100 VA.  Models are available with input voltage ratings from 115V through 460V, 50/60 Hz, including dual voltage models for North American/European applications. Output voltages are 24V or 26.5V. These transformers are suitable for HVAC, appliance, vending, battery charging, security, irrigation control, lighting control, and other applications requiring a Class 2 or SELV safety isolating transformer. Connection options include lead wires, glow wire compliant terminals, and terminal blocks.
