Alter® SM 1690
Air-cooled Switch Mode Microwave Power Supply for 10kW, 2.45 GHz Magnetrons
The SM 1690 magnetron power supply is an air-cooled power supply designed to drive the compact H915 magnetron with permanent magnet, with power of 10 kW @ 2.45 GHz.
For power control versatility, the output power of the SM 1690 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.
Available in either 400 or 480 VAC line voltage configurations, the SM 1690 is designed to power and control MKS, Alter Products TM100 microwave magnetron head; however it will also power other manufacturer's electrically compatible heads.
The SM 1690 autonomously manages the working status of the magnetron, providing signals to drive the correct pre-heating of the filament and to adjust the filament voltage according to the specific back down curve. In addition, the power supply automatically shuts off the output power in the event of an alarm condition, such as over current or over voltage of the magnetron.
The SM 1690 power supply is packaged in a 19-inch wide, 7U high rack mount enclosure and is built with a rugged steel base and easily removable aluminum panels. Industry standard electrical connectors, dedicated to specific functions, provide simple and easy set up. The power supply high voltage (HV) output, carrying the anodic current, is delivered through an HV connector.
