Hammond 171F 750VA Plug-In 115VAC Isolation Transformer, NEMA 5-15

The 171F is a 750VA plug-in isolation transformer that takes a 115VAC, 50/60 Hz input and delivers 115VAC on the secondary, providing complete circuit isolation for equipment users, test technicians and integrators.

An electrostatic shield between primary and secondary greatly attenuates surges and noise; typical surge/noise suppression is -32 dB, with typical capacitance between windings of 20 pF at 1 kHz. Every unit is hi-pot tested to 2 KV RMS, and the primary is protected by a 7 amp circuit breaker. Typical full-load efficiency is 95% and typical full-load total harmonic distortion is 0.24%, with leakage current under 100 µA (typical).

Installation is plug-and-play: the input (primary) connects through a 5 foot cord with a standard North American NEMA 5-15P plug, and the output (secondary) is a 1 foot "pig tail" cord ending in a 3-wire grounded NEMA 5-15R receptacle with North American pins. The 298G adaptor series provides international pinout adaptor plugs. The unit is for indoor use only and does not convert line frequency.

Overall dimensions are A 4.40 in (112 mm), B 8.70 in (221 mm), C 5.39 in (137 mm), D 3.50 in (89 mm) and E 6.78 in (172 mm). The 750VA 171F moves to a larger 4.40 in (112 mm) by 5.39 in (137 mm) frame with the longest B dimension in the range, 8.70 in (221 mm), and a 7 amp primary breaker. The 171F carries the North American mark of safety, C UL and UL listed (File #E211544), and is RoHS and REACH compliant.
