The Sorensen DCR60 series (comprising phase-controlled SCR models such as the DCR 60-1.5B, DCR 60-3B, DCR 60-7B, DCR 60-14B, DCR 60-45B, and DCR 60-115B) provides highly regulated, precise, and adjustable DC output up to 60V. Utilizing Silicon Controlled Rectifier (SCR) or Triac technology at the transformer input followed by a passive LC filter, the DCR60 series delivers highly efficient regulated power with excellent transient recovery times and automatic crossover between voltage and current modes.
