Sola/Hevi-Duty Introduces New Line of Three-Phase Power Conditioners

October 22, 2000 by Jeff Shepard

Sola/Hevi-Duty (Skokie, IL) introduced a complete product line of three-phase power conditioners ranging from 10KVA to 150KVA, which are available in most voltage configurations. The company claims that these hard-wired power conditioners are designed to protect equipment from voltage sags, swells and spikes, switching transients, lightning, and induced surges by means of a surge-suppression circuit linked to a shielded isolation transformer and input/output filters.

The new power conditioners are claimed to be an ideal solution for situations in which even a small change in the voltage level could lead to unscheduled downtime, mis-operation and scrapped production. Such circumstances might include commercial or industrial applications where computers, automated assembly, and processing or PLC-based equipment are being used.

Sola's three-phase power conditioners are intended to maintain output voltage regulation to a maximum of +/-5 percent, even with an input voltage of between -25 percent and +15 percent. Additionally, they can be used as a step-down transformer. The units also provide a K-factor transformer design, which is intended to prevent overheating caused by harmonic loading, as well as other such standard features as regulation of output, overload and over-temperature indication, a maintenance bypass switch, and an input circuit breaker. Response time to any line variation is reported to be less than 1.5 cycles, despite the condition of lines, loads or power factors.

The units operate with 150dB common-mode noise attenuation and 65dB normal-mode noise attenuation at 100kHz. They come packaged in a NEMA 1 steel enclosure, are UL listed and are cUL certified. Custom voltage configurations are also available.
