Hammond 185C230 25VA 230V Center-Tapped Chassis Mount Transformer

The 185C230 is a 25VA low voltage chassis mount power transformer from the 185 Series, built for global use with a dual 115/230 VAC primary and 50/60 Hz operation. It suits OEM engineers, panel builders and equipment designers who need one transformer that can be wired for either mains voltage.

Unlike the low-voltage C-size models, the 185C230 has a 230V C.T. secondary rated 0.11A in series, or 115V at 0.22A in parallel, at 25VA. The dual secondaries are brought out for series or parallel connection, and the primaries are wired in parallel for 115V or in series for 230V.

Construction uses a dual bobbin with Class F insulation (155 degrees C), and the unit is 4,000 V RMS hipot tested. Dual use terminals accept either solder or quick connect termination; terminal lugs are listed at 0.19 in wide and 0.02 in thick.

The 185C230 measures 2.81 in wide, 2.22 in deep and 2.31 in high (71 x 56 x 59 mm) including the mounting feet, weighs 1.25 lbs and ships at 1.35 lbs (0.61 kg). It chassis mounts per mounting figure A, with a 2.37 in hole-to-hole width. Listings include C UL US recognition (E207860), TUV Type Approval and CE certification to IEC 950 (EN 60-742 Safety Isolating Transformers); it is RoHS and REACH compliant.
