Alter® SM 1250 Air-cooled Switch Mode Microwave Power Supply for 3kW, 2.45 GHz Magnetrons
Overview
The SM 1250 magnetron power supply is a compact, air-cooled, switch-mode power supply designed to drive most nominal 3 kW @ 2.45 GHz magnetron models. For power control versatility, depending on the model, the output power of the SM 1250 can be variably adjusted from 10 to 100% using an external 1 to 10 VDC analog signal, or by remote control through a fieldbus interface or by front panel commands.
- High efficiency power supply design requires only air cooling - simplifies installation & reduces cost
- Low output ripple - suitable for most applications
- Advanced filament control for low maintenance and long magnetron life
- Efficient power stage design for low harmonics and inrush current
- "Plug & Play" design for fast & easy installation
