Hammond 186B24 6 VA 24V C.T. Dual-Primary Chassis Mount Transformer

The 186B24 is a 6 VA low voltage power transformer from the 186 Series, the dual primary (115/230 VAC) half of the 186-187 family. It provides a 24V C.T. secondary rated at 0.25 A and operates on 50/60 Hz, suiting OEM engineers, electricians and equipment builders who need a small chassis-mounted low voltage supply that can run from either 115 V or 230 V.

It uses an economical open style, channel frame chassis mount design with combination solder or quick connect terminals. Split bobbin construction eliminates the need for an electrostatic shield, insulation material is Class B (130 C), and the design keeps temperature rise from exceeding Class A for longer life. Each unit is hi-pot tested to 2 KV RMS.

Dimensions from the series table: length (L) 2.37 in (60 mm), depth not including terminals (B) 1.25 in (32 mm), height (C) 1.37 in (35 mm), mounting centers (D) 2.00 in (51 mm) and depth to terminal (E) 1.62 in (41 mm). The shipping weight is 0.45 lbs (0.20 kg).

If only a 115 VAC single primary is needed, the series table lists 187B24 as the matching 187 Series part with the same 24V C.T. secondary and 0.25 A rating. The 186-187 Series is UL listed (# E207860) Type 3AH and CSA certified, and the 186B24 is RoHS and REACH compliant.
