Up to five units can be connected in parallel when the single wire current share is utilized to obtain an output power of 4,500W. The power supplies can also be used in series for voltage increases. The output can be remotely programmed using an external resistance or voltage. A 12V, 100mA auxiliary supply is available to drive external circuits. Variable speed, high reliability fans are utilized in the design for both lower acoustical noise and longer fan life. Active power factor correction is incorporated into the design to meet EN61000-3-2.
