Linear DC Power Supply

 

A linear DC power supply regulates the output voltage through a big transformer and then by dropping excess voltage in a series dissipative components. Regulated linear DC power supplies have very good load and line regulation, and have very little ripple and noise.

 

For three decades, we have made variable regulated linear power supplies with exceptionally low ripple and noise, at a franctional cost of established brands. Our success has attracted a number of copycats with lookalike products. In 2012, we adopted new designs that improved reliability and fault tolerance of a linear DC power supply to the next level. After three years of testing, we are happy to confirm that the new Volteq line of linear DC power supplies has met all of our expectations in terms of voltage and current regulation, noise, and reliability, and is the most reliable and robust linear DC power supply in the market.

Typical applications of regulated  linear DC power supplies include but not limited to:

  • low noise amplifiers
  • signal processing
  • data acquisition - including sensors, multiplexers, A/D converters, and sample & hold circuits.
  • automatic test equipment
  • laboratory test equipment
  • control circuits
  • anywhere that excellent regulation and/or low ripple is required
