Among Triad Magnetics’ extensive selection of power supply transformers — designed for both direct use or for use in transformer, rectifier, or filter circuits — is our line of over 100 Single Secondary Chassis Mount power transformers.

Our single secondary chassis mount power transformers are available in single primary with single secondary configurations, as well as in single primary with multiple secondary configurations. They are available in a number of our usual compact sizes, ranging from 3 9/16 in mounting width to as small as 1 ¾ in, and have a standard mounting hole size of 3/16 in.

With primary voltages of 115 V or 230 V and secondary voltages — including control, filament, and low level signaling — from 2.5 V to 60.0 V, our single secondary transformers are ideal for a large number of applications.
