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.
The compact and innovative design of these units make them highly competitive alternatives to traditional, transformer based, power supplies. The output power can be adjusted from near zero up to 100% using an external analog signal.
CM 340 and CM 440 magnetron power supplies independently monitor and control the operating status of the magnetron, providing power to drive the correct pre-heating of the filament and switching off the output in the event of an alarm condition such as over current or over voltage of the magnetron.
Industry standard electrical terminal blocks with separate terminals for all electrical functions provide simple and easy set up. The high voltage output, carrying the anodic current, is available with an HV connecter or, upon request, with a preassembled HV wire.
Both the CM 340 and CM 440 are enclosed in a lightweight and compact aluminum housing designed to be easily mounted inside an electrical enclosure. External interlock contacts are provided to allow for the use of industry standard internal safety lockout procedures typical of systems housing high powered supplies.
