Hammond 176B 200VA 115V to 230V Plug-In Step-Up Autotransformer

The Hammond 176B is a 200VA plug-in step-up autotransformer that raises 115VAC to 230VAC at 50 or 60 Hz. It suits technicians, integrators and labs running 230V equipment from a standard North American outlet, where the equipment is already isolated and only a voltage change is required.

It uses a single winding and does not provide isolation. The input is circuit breaker protected, and the unit is hi-pot tested to 2 KV RMS. The 176B doubles the capacity of the 100VA model to 200VA while keeping the same 3.16 in A and 3.81 in C dimensions, and weighs a listed 4.5 lbs.

Input is through a 5 foot cord with a standard grounded North American plug (NEMA 5-15P). Because of U.L. changes in 2007, production after the first part of 2008 replaced the European (Schuko) output with a one foot long "pig tail" cord and a standard North American 3-wire, 250V receptacle (NEMA 6-15R). Receptacles have North American pins, and the 298G adaptor series provides international pinout adaptor plugs.

The 176B measures A 3.16 in (80 mm), B 4.50 in (114 mm), C 3.81 in (97 mm), D 2.50 in (64 mm) and E 3.19 in (81 mm). It is C UL and UL listed (File #E211544), RoHS and REACH compliant, and for indoor use only. These units do not convert line frequency.
