The Alter® SM 445 is an air-cooled power supply for a 1.25 kW magnetron. The SM 445 is able to power and control most types of magnetrons available on the market with nominal power of 1.25 kW @ 2.45 GHz. Depending on the model, the output power can be adjusted continuously, from 10% to 100%, using an external analog signal from 1-10VDC, with a PC via USB port, or by front panel commands.
Proven, state-of-the-art design with resonant topology that improves efficiency
Single phase input requirement, at nominal 230 VAC, includes Power Factor Correction (PFC) stage
Low output ripple, suitable for most applications, and stable filament control result in long magnetron life
Very low harmonics and inrush current from efficient power stage design
"Plug & Play" - when installed with Alter® cable set the user supplies only 2 signals
