These are 48 volt blower power, auxiliary low voltage to other modules, and drive for a high frequency filament supply. It also contains its own control and protective circuits and its own control power circuit, which is power factor corrected once in operation. Advantages of MCL's Active Power Factor Correction With active power factor correction, it is possible to accommodate a wide range of input voltages and frequencies at the input, while the output voltage is a well-regulated constant value. For MCL's customers this means that the amplifier is less sensitive to input voltage variation. For MCL it means there is only one universal input power option which simplifies both the operations and sales process.
Inventory is reduced, while the possibility of assembly and testing errors is minimized.
Since the PPC produces constant internal interfaces regardless of input voltage, there is no need to change blowers, auxiliary power supplies, breakers or transformer taps to accommodate different input voltages. Active power factor correction is just one of the innovative features that MCL has incorporated into our amplifiers. Like active power factor correction, the benefits of some of these features are often unknown to the customer. However, together they make MCL's products the most advanced and innovative power amplifiers available to the satellite industry. For more information, please contact us .
