DC - AC Sinewave Inverters for True Mains Power
High performance, lightweight and compact design for fully isolated sinewave mains power. Power Conversions PowerMax DC to AC true sinewave inverters supply mains power where the mains is unavailable or unreliable.High frequency, switch mode, double conversion topology enables the PowerMax sinewave inverter to efficiently produce a whisper quiet, low distortion AC output voltage, with excellent output voltage regulation over the total input DC voltage range, even when subjected to sudden load step changes or high crest factor loads. Maintains low DC noise current and RFI levels.
19 inch rack mounted, industrially rugged PowerMax sinewave inverters generate continuous mains power from an input voltage range of 12Vdc to 220Vdc. Fully protected for maximum reliability with input and output thermal/magnetic circuit breakers and transient protection. Input reverse polarity protection, de-sparking and input DC over and under voltage shutdown. Also AC current limiting, overload and short circuit protection.
Designed to supply large inrush/start-up currents and high crest factor loads as drawn by computers or other electronic equipment, the PowerMax sinewave inverter is ideally suited for modern switchmode equipment.
Australian made, with a two year comprehensive warranty, support is always close at hand.
Leading technology and quality manufacture ensure reliable AC power
