Signal's MT and DMT series chassis mount triple output transformers are designed to provide regulated power supplies for 5 VDC and either 12 VDC or 15 VDC. These transformers offer the same performance features as the 241 series and are available in multiple power ratings (30 VA, 56 VA, and 100 VA). They feature single or dual primaries with a nominal input of 115 V or 115/230 V at 50/60 Hz, and an input range of 100 V to 130 V or 200 V to 260 V. The transformers are built with solder lug/quick connect terminals and Class B insulation (130 C), ensuring reliable operation. They are RoHS compliant and carry UL and CSA certifications.
