PC21-F25B-1000 WATLOW

Ihe Power Series is a state-of-the-art microprocessor-based Silicon Controled Rectifier(SCR) power controller intended for controlling industrial heaters. This product is based onone package with several configurations that include single phase, three phase, and singlephase-multizone capabilities. Each package configuration has a specific current ratingdepending on the number of phases switched. The switching capabilities include 65 to 250Arms at 50'C from 24 to 600V~ depending on the configuration or model number selected. Seepage 1.2 for additional information on the Power Series configuration options.

The Power Series must be mounted in a suitable electrical enclosure. It musthave adequate wire bending space and cooling. The maximum ambienttemperature in the enclosure must not exceed 50°C (122'F) for name platerating. For other output ratings and enclosure ambient temperatures, see outputrating curves on pages 2.5 and 2.6.To maintain the proper cooling, the enclosure must be large enough to dissipatethe heat generated by the Power Series, or there must be some form of activecooling.

Air circulation - fans bring air into the bottom of the enclosure and louverplates to allow the air to exit the top of the enclosure. Filters are notrecommended as they can become plugged and block air flow. To maintain80 percent of the CF'M of a fan, the outlet must be four times the area of thefan inlet. Ensure that each Power Series is within an unobstructedairstream.

2.Vortex coolers operate on compressed air and provide good cooling on asealed enclosure, but are noisy and consume a lot of air.Cabinet air conditioners work well on sealed enclosures.Heat pipe coolers work well on sealed enclosures, but do not provide as4.much cooling as vortex coolers or air conditioners.
