300 Voltampere 480:240 Volt Auxiliary Power Transformer
TSTM Inc. has introduced a higher voltampere (300 voltampere at 55C) version of its line of auxiliary power transformers many refer to as “hockey pucks” because of their black cylindrical shape. This larger voltampere design enables use on loads where the voltampere burden exceeds the capabilities of standard auxiliary power transformers.

These larger transformers share a conduit fitting with the smaller transformers, which simplifies installation on the outside of a meter socket or other electrical cabinet. If there is room in the cabinet interior, the transformer can simply be placed in any convenient location.

These compact and efficient toroidal type autotransformers make wiring to automatic meter reading / advanced metering infrastructure (AMR/AMI) devices or other loads much less difficult and time consuming than conventional transformers. The transformer design also enables them to pass power line carrier signals—making them suited for virtually any power line carrier based device.
