Alter® SM 445 Air-cooled Switch Mode Microwave Power Supply for 1.25 kW, 2.45 GHz Magnetrons with PC Connectivity
Overview
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
