Howard Industries Micro-Power is a
compact and light-weight oil-filled polemounted distribution transformer
designed to serve small, isolated loads.
Typical applications include capacitor
banks, reclosers, station control power,
billboards, microwave and cellular tower
sites, water pumps, security lights,
streetlights, traffic signals, and railroad
signals. Micro-Power transformers
provide an economical alternative to
larger standard-size transformers in a
lightweight package starting at under 100
pounds |
