Headquartered on Long Island New York, SPI has been manufacturing switching mode power supplies since 1976. With over 40 years of experience in the power supply manufacturing industry, we realize customer satisfaction is the key to a successful business. Our knowledge in power development enables us to offer standard and custom designed products for a wide variety of electronics. From shipborne to airborne and from ground based to mobile, SPI's strength is in using our standard building block topologies to fulfill each individual program requirement. This combined with our high level of vertical integration results in a low risk approach and gives us the ability to deliver quickly.
A few recognizable achievements include the development of a low leakage EMI line filter, and a patented front end, passive, power factor correction module (rated at over one million hours of MTBF). Most recently, we patented a 3 phase input topology with active power factor correction which cancels out all harmonic power line frequencies on the output ripple thus eliminating the need for additional output LC filters (extremely reliable & saves weight!).
