The 172F is a 1000VA plug-in step-down isolation transformer that converts a 230VAC, 50/60 Hz supply to 115VAC while providing circuit isolation. It suits integrators, lab users and equipment builders who need to run 115VAC North American equipment from a 230VAC source.
An electrostatic shield sits between primary and secondary, the unit is hi-pot tested to 2 KV RMS, and it has a circuit breaker in the primary. Measured performance: leakage current 94.08 µA, full-load efficiency 96%, full-load total harmonic distortion 0.18%, surge/noise suppression -32.74 dB and capacitance between windings of 40 pF at 1 kHz.
The input (primary) is a 5 foot cord; per the series notes, current production uses a standard North American 3-wire, 250V plug (NEMA 6-15P), which replaced the European (Schuko) plug found only on old inventory after U.L. changes in 2007. The output (secondary) is a 1 foot cord ending in a standard North American 3-wire grounded NEMA 5-15R receptacle with North American pins; the 298G adaptor series offers international pinout adaptor plugs. The unit is for indoor use only and does not convert line frequency.
Overall dimensions are A 5.28 in (134 mm), B 7.75 in (197 mm), C 6.38 in (162 mm), D 4.25 in (108 mm) and E 6.00 in (152 mm), with a shipping weight of 34.5 lbs (15.65 kg). The 1000VA 172F is the highest-capacity 172 model, built on the 5.28 in (134 mm) by 6.38 in (162 mm) frame, with 96% full-load efficiency and 40 pF capacitance between windings. The 172F carries the North American Mark of Safety, C UL and UL listed (File #E211544), and is RoHS and REACH compliant.
