The 185D16 is a 43VA 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.
The 185D16 delivers 16V C.T. at 2.7A in series or 8V at 5.4A in parallel from the 43VA D-size frame. 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 185D16 measures 3.12 in wide, 2.22 in deep and 2.68 in high (79.2 x 56.4 x 68.1 mm) including the mounting feet, weighs 1.75 lbs and ships at 1.63 lbs (0.74 kg). It chassis mounts per mounting figure A, with a 2.81 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.
Ideal For
- Chassis-mounted low-voltage AC supply in equipment and control panels
- Equipment built for global use on 115 or 230 VAC, 50/60 Hz
- 16V center-tapped or 8V parallel secondary supply
- Designs needing solder lug or quick connect transformer terminals
