Alter® CM 340/CM 440 Compact, Air-cooled Microwave Power Supplies for 1.0 & 1.2 kW, 2.45 GHz Magnetrons

CM 340 and CM 440 magnetron power supplies are compact, air-cooled power supplies designed to drive magnetrons having a maximum power of 1.0 and 1.2 kW. The CM 340 is able to power and control most magnetron models within the nominal range of 900 W to 1 kW at 2.45 GHz while the CM 440 power supply provides the same performance for magnetrons with a nominal maximum power of 1.2 kW at 2.45 GHz.

Compact & lightweight form factor - ideal for installations where saving space is critical
High efficiency power supply design requires only air cooling simplifying installation and reducing cost
Medium output ripple is suitable for industrial heating applications
Easy assembly inside an electrical enclosure, with access to the terminal block on the bottom of the unit and output on the top
