Product Description

Product Overview

The Signal MPL Series Triple Output Transformers are designed for regulated power supplies requiring 5 VDC and either 12 VDC or 15 VDC. Featuring hum-bucking (semi-toroidal) construction, these transformers minimize radiated magnetic fields, making them ideal for critical low-height PC board applications. They offer dual primaries and dual complementary secondaries, with electrostatic shielding not required due to split bobbin construction. Available in 6 VA and 12 VA power ratings, these transformers are UL recognized and CSA certified.
