Hammond 187E10 10V CT 50VA Chassis Mount Power Transformer

The 187E10 delivers a 10 V center-tapped secondary at 5 A, 50 VA in total, in the E-size channel frame. It belongs to the 187 series of chassis-mount, low-voltage power transformers, which run on 50/60 Hz and suit OEM engineers and panel builders who need a fixed step-down secondary with a center tap. If you need a dual 115/230 VAC primary with the same secondary, the ordering table pairs this part with the 186E10. The part page's primary-voltage attribute reads "115 / 230 VAC", while its descriptions, the 186E10 cross-reference and the ordering table place 187E10 in the 115 VAC single-primary column; confirm the primary configuration against your design before ordering.

Construction is an economical open-style channel frame for chassis mounting. Split bobbin construction removes the need for an electrostatic shield, insulation is Class B (130 °C), and temperature rise is designed not to exceed Class A for longer life. Combination solder or quick connect terminals allow either soldered leads or quick connect wiring.

In the E-size frame, the 187E10 measures 3.68 in (93 mm) long, 1.81 in (46 mm) deep not including terminals (2.19 in (56 mm) to the terminal), and 2.25 in (57 mm) high, with 3.12 in (79 mm) mounting centers. Shipping weight is 1.7 lbs (0.77 kg).

The series is hi-pot tested to 2 KV RMS, UL listed (# E207860) Type 3AH and CSA Certified. This part is listed as RoHS and REACH compliant.
