Our LS Series Linear AC Power Sources provide clean, regulated power at competitive prices. Linear technology reduces total harmonic distortion (THD) across the instrument’s output frequency range while improving performance for high crest factor loads. Monitor voltage, current, frequency, and power/power factor via front panel display. Quickly set and change test parameters with the easy-to-use front panel push button interface. Built-in safety features protect the instrument, the operator, and the DUT, ensuring a safe work environment. Optional Low Range Meter Resolution is perfect for manufacturers looking to measure low power consumption commonly found in Energy Star standards. The LS Series includes the following models: LS 500, LS 1000.
