PCB Mount Transformer Specs

Picture5Description

This series of PC Mount Toroidal Power Transformers is optimally designed for triple output power applications. 

Coupled with user supplied rectifiers, filter capacitors, and series voltage regulators, they provide 5VDC and either ±12 or ±15VDC.

The units are fully encapsulated and sealed with pinned bases for circuit board mount and flow soldering. This provides quick assembly with a very clean appearance. Each case has five mounting holes for sturdy and flexible mechanical assembly.

Multi-tapped inputs allow system compatibility with any international line voltage. Cores are toroidal grain oriented silicon steel, the most efficient magnetic element. This yields maximum electrical efficiency, low temperature rise, dead quiet operation and an extremely low external magnetic field. Applications include instrumentation and digital equipment.

Approvals The series is recognized by Underwriters Laboratories to UL506, UL1411, and CSA22.2 #66-1988. File # E156800.
Inputs Dual 0-100-120VAC windings to be series or parallel connected for 100, 120, 220, or 240VAC operation at 50 or 60Hz. See
Insulation Primary to secondary: Polyester tape. Class B (130° C.), four layers minimum. Meets high potential voltage test requirement of >4 kV for 1 minute.
Temperature Rise Maximum 40° C. At maximum rated load, continuous.
Application The voltage rating for the rectifiers, capacitors and regulators must be greater than the values shown in the Secondary Application Schematic. Also the rectifiers and regulators must be selected for the actual DC currents in the application, refer to Ratings Table.
Case The case material is black Polyamide 6, UL certified 94HB, class B.
