HPS Imperator™
Encapsulated Industrial Control Transformers
INNOVATIVE DESIGN
The HPS Imperator’s unique terminal block design allows
for the quick and easy installation of standard secondary or
optional primary 13/32” x 1 1/2” midget/type CC fuse clips
on every unit. This is the simplest and most inexpensive
fusing installation provided on any industrial control
transformer in the market today.
THE PERFECT SOLUTION
With 11 standard voltage groups, a VA range from 50VA
to 1500VA and available with standard secondary and
optional primary fuse kits, the HPS Imperator series
provides the perfect solution for any application.
SUPERIOR QUALITY & VALUE
The HPS Imperator series design, utilizing superior insulation
systems and being constructed with high quality silicon steel
laminations for optimum performance, meet or exceed UL,
CSA and CE standards.
