Introducing the LMX Series – High Performance Linear AC Power Source up to 6kVA, or 30kVA option

When high power quality matters, the new for 2020 LMX Series family of High Performance Linear AC Power Sources is the answer. The linear amplifiers within the LMX Series power sources are unmatched in their ability to produce the high crest factorlow-distortionhigh fidelity output waveforms required by the most demanding AC Test Power applications. Stand-alone models range from 500 VA to 6 kVA. Larger chassis may be paralleled to create systems that range from 8kVA to 30 kVA. Offering both single and three phase models, units are conservatively designed with output power ratings based on the most severe combination of input line, output voltage, power factor, and temperature.
