PWII

The Pure Wave II (PWII) was built upon our industry proven PW-Series to engineer a new Dimmable Class of Lighting Inverters with serviceability and flexibility at the forefront of design. Equipped with Pure Sine Wave output, 10X crest factors to punch through the most demanding inrush requirements, 3 configurable lighting zones for seemless system integration, field-selectable Input/Output AC voltages, and ultra-low standby power consumption to meet the California Energy Commission requirements. The PWII offers an industry-leading option of a 3 channel DALI / 0-10V transfer circuit with independent selectable preset dimming levels for each output.
