Isolation Transformers Can be Used for Step-Up, Step-Down or 1:1 Voltages

Foster Transformer introduces a line of RoHS compliant isolation transformers which are suitable for step-up, step-down and 1:1 voltage applications. An electrostatic shield between the primary and secondary windings enhances safety and provides suppression of transients and electrical noise. When used in a 1:1 configuration, these isolation transformers protect sensitive electrical equipment installed in electrically "noisy" environments and allow the use of commercial grade printers, computers and other peripheral devices in medical equipment by isolating them from mains power. Their higher efficiency, lower temperature rise, Class 180 Insulation Systems and layer wound construction allow Foster Isolation Transformers to last longer than comparably rated models. These transformers are ideal for use with EN 60601-1medical devices and equipment as well as industrial and commercial products including industrial controls, commercial appliances, machine tools, and more.

When used as step down transformers, they allow equipment designed to operate from a 120V power source to operate in areas where the voltage is nominally 208 V or 240V. When wired for step-up operation, these transformers allow equipment designed for 208 V or 240V operation to operate from 120V service. Regardless of how they are employed, Foster isolation transformers protect sensitive equipment from transients and noise inherent in many utility power lines.

With power ratings from 0.025 kVA (25VA) to 5.0 kVA, and Class 180 insulation, these transformers are UL Listed and C-UL Certified to UL 5085/CSA 22.2No.66, UL File Number E19598. Input voltages 120/208/240V at 50/60 Hz, with output of 120/208/240V 50/60 Hz. Custom configurations and applications specific wiring harnesses are available.
