The Sorensen DCR150 is a series of highly regulated, SCR-controlled programmable DC power supplies from the DCRA/B family, designed for both benchtop and rack-mount applications. These phase-controlled systems feature Silicon Controlled Rectifiers (SCRs) or Triacs paired with passive LC filters, offering reliable, high-power DC outputs with high efficiency and robust protection features such as over-voltage protection (OVP) and remote sensing.
