Low Ripple Switch Mode Power Supply for Magnetrons
Low Ripple Switch Mode Power Supply
  • Low Ripple Switch Mode Power Supply (LRSMPS) for Magnetrons 2, 3, 5 or 6 kW
  • 19" Rack
  • Air- or watercooled
  • Low Ripple Current ≤ 2% , ideally for plasma applications and other most applications
  • Microcontroller based Monitoring and Controlling of all important Magnetron Operating Parameters like High Voltage and Current. The LRSMPS ensures that the Magnetron is always operating in the ideal Operating Point (longer Magnetron lifespan)
  • Low electromagnetic interference, improved fail-safe design against electromagnetic interference‘s
  • No electromagnetic interference, much more fail safe against electromagnetic interference's
  • Personal protection against accidental contact with the high voltage
  • Improved alarm visualization, all alarms are described and displayed in plain text
  • Two different control options to suit most application requirements (e.g. PLC control or fieldbus control capabilities)
  • Profinet-Interface
  • Delivery time for SMPS 6kW / 2.45 GHz and SMPS 5kW / 915 MHz (depending on the quantity requested): max. 1 week

High Voltage Power Supply for PH-GEN series phase-angle control
Mikrowellengeneratoren der Serie LC-GEN Mikrowellengeneratoren der Serie LC-GEN

The PH-GEN power supply unit is used to supply power to a magnetron. It is mounted on a mounting plate and consists of 5 components: Mains filter, control card, high voltage transformer, choke and high voltage bridge. To generate microwaves, only an air- or water-cooled magnetron and a heating transformer are needed. With the help of a potentiometer or a 0..10 Volt control voltage, the power can be adjusted very finely and continuously. A voltage between 0 and 5 volts is output at the analog output, which is proportional to the actual value of the microwave power. Furthermore, the magnetron temperature and the anode current are monitored. In the event of a fault, the power supply unit is switched off and an error message is output via a potential-free relay contact.

Technical Datas:

  • Supply voltage: 230 / 400 Volt, 50 Hz
  • Microwave power:
    • 600 Watt
    • 1000 Watt
    • 1200 Watt
    • 1500 Watt
    • 2000 Watt
    • 3000 Watt
  • Efficiency: ca. 95 %
  • Pulse frequency: 100 Hz
  • Anode current: Up to 840 mA
  • Dimensions (WxHxD): 600 – 1200 Watt: 395 x 180 x 225 mm
  • From 2000 Watt: 460 x 220 x 280mm
High Voltage Power Supply for Microwave Generators LC-GEN Series
LC-stabilized Generator
The LC-stabilized LC-GEN generators have a simple and robust design. They allow to radiate the 2.45 GHz microwaves with a pulse frequency of 5 Hz. With an internal square wave generator it is possible to control the output power from 0 to 100%. The power of the generators reaches from 300 W to 3.0 kW. Power supply and magnetron head are two separated units.
Generator type LC-COM
Generator LC-COM
The generator type LC-COM is a compact low price alternative to the LC-GEN type. Power supply and magnetron head are joined together in a very compact form. It is possible to switch on and off the unit with an external signal for controlling the mean power. The power of the compact generator reaches from 300 W to 1 kW.

All components of the generators, like control cards, transformers, diodes, capacitors, magnetrons etc., are also available separately.
