Programmable AC Power Supplies | Pacific Power Source

Customer Support



Pacific Power Source designs and manufactures both linear and switched mode (PWM) AC Power Sources. We provide technically advanced, reliable, and cost effective standard and custom precision programmable AC Power Solutions that feature fast transient response, tight regulation, high peak current capability, no switching noise (linear) and low switching noise (PWM switching) models and low output impedance.

Linear AC Power Sources

Our Linear AC Power Sources  (New LMX Series and Legacy AMX Series) produce low-distortion, high fidelity, output waveforms. The advantage of linear amplification is its ability to faithfully reproduce oscillator waveforms with very high small signal bandwidth and low output distortion.

PWM AC Power Sources

LSX Series, ADF SeriesAFX Series, AZX Series and MS Series offer very good power density, high efficiency, and perform well into low power factor loads. They use a combination of both linear and non-linear methods to achieve high efficiency conversion in lighter and smaller packages.
