Rugged two piece ventilated steel enclosure. Finished in a grey/beige color, textured powder paint with rubber feet installed. NOTE 1: Due to the nature of ferroresonant designs - these units do produce audible noise. We have reduced this through careful design, but these units are NOT usable in an office environment. NOTE 2: These units provide complete isolation from the source voltage. In other words, the "neutral" output wire has no connection to ground, this is a UL requirement for this type of device. Therefore plug-in circuit testers & line "polarity" testing devices will NOT function on the output as it is completely isolated. North American Mark of Safety: C UL & UL listed (File #E211544).

Transformer - Selection Guide Steps To Proper Transformer Selection 1. 2. 3. 4. What power is available (you need to know both voltage & frequency)? Check the operating voltage of your equipment (is it single voltage or multiple?). What line frequency will your equipment run on? Either 50, 60 or dual 50/60 Hz. (remember, a transformer can NOT change line frequency). Use the chart below to determine your requirements: Power Available Your Equipment Transformer Type Required Voltage Frequency Voltage Frequency (You may also need plug adaptors) 115 60 100 50/60 Step Down 115 50 115 50 None Required - or - Straight Isolation 115 50 115 60 Will Not Work 115 50 115/230 50/60 None Required - or - Straight Isolation 115 60 115 60 None Required - or - Straight Isolation 115 60 230 50 Will Not Work 115 60 230 60 Step Up 115 60 115/230 50/60 None Required - or - Straight Isolation 230 50 115 50 Step Down 230 50 115 60 Will Not Work 230 50 115/230 50/60 None Required - or - Straight Isolation 230 60 115 60 Step Down 230 60 230 50 Will Not Work 230 60 230 60 None Required - or - Straight Isolation 230 60 115/230 50/60 None Required - or - Straight Isolation 1. Determine if your equipment is Electronic or Electrical: - Electronic = containing IC chips, transistors or a circuit such as a radio, shavers, electric toothbrush, computer printers, camcorder battery rechargers etc...(if in doubt, check with the manufacturer or refer to your manual). - Electrical = Simple heating device, such as irons, hair dryers, electric blankets, curling irons, etc... 2. Use the chart below to locate correct series & voltage conversion in the catalog series that follow: Transformer Type (determined from Your Equipment Type chart above) Electronic Electrical Step Up Use Isolation (series 298) Could use Auto (series 170 or 170E) Step Down Use Isolation (series 172, 179 or 289) Could use Auto (series 175) Straight Isolation Use Isolation (series 169 or 171) - IMPORTANT NOTES Isolation Transformers: Used for maximum safety, versatility (can be used on both electrical & electronic equipment) and isolation from the power source, used to step-up, step-down or for straight isolation. The disadvantage to using them is weight (about double the "Auto"), more expensive and larger size. This type of transformer is sometimes referred to as "double-wound" "Auto" Transformers: are non-isolating units and should be used where only a voltage change is required. The advantages to using them are light weight (generally half that of an isolation unit), less expensive and smaller size. The disadvantage is no isolation from the power source. This type of transformer is sometimes referred to as a "converter". Adaptors: We strongly recommend that 3-prong "grounded" plugs be used with all of our products. They should be used only with our "grounded" adaptors. Adaptors do not affect voltages, they are a mechanical device only to match foreign "pin-outs" of receptacles and/or plugs.
