Modular Power Supplies

Enclosed switching power supplies make an excellent alternative to linear regulators because they are lighter, smaller, and more efficient. While switching power supplies are more complex than linear benchtop power supplies, our high-performance switched-mode power supplies are quiet and well-regulated. In addition, they feature input power factor correction and generally cost less than an equivalent linear power supply.
