The CM 330 Magnetron Power Supply is a compact, air-cooled, switch-mode power supply with an integrated filament transformer designed to drive a 1 kW magnetron. The CM 330 power supply is able to power and control 2M244 type magnetrons with a maximum power of 1 kW @ 2.45 GHz. The output power of the CM 330 can be adjusted from 10% up to 100% using an external, linear 0 - 10 V analog signal.

The CM 330 power supply incorporates a power factor correction stage (PFC) that widens the usable input line voltage range from 160 VAC to 260 VAC and also stabilizes the filament control. The compact and innovative design of the CM 330 power supply makes it a highly competitive alternative to traditional, transformer based, power supplies.

The CM 330 autonomously manages the working status of the magnetron, providing power to drive the correct pre-heating of the filament and to automatically shut off the output power in the event of an alarm condition, such as over current or over voltage of the magnetron.

The CM 330 power supply is enclosed in a lightweight and compact aluminum housing designed to be easily mounted inside an electrical enclosure. Industry standard electrical terminal blocks with separate terminals for all electrical functions provide simple and easy set up. The high voltage (HV) output, carrying the anodic current and the filament current, is available via two preassembled HV wires. As the unit includes the filament transformer, it should be assembled as close as possible to the magnetron, within the length of output wires.

Features & Benefits

  • Compact and lightweight form factor suitable for installations where the space saving is mandatory.
  • Highly competitive alternative to larger/heavier traditional L-C power supplies.
  • High efficiency power supply design requiring only air cooling simplifies installation and reduces cost.
  • Low output ripple makes it suitable for laboratory and professional oven equipment.
  • System designed for easy assembly inside an electrical enclosure, with access to the terminal block on the bottom of the unit and output on the top.

Applications:

CM 330 is designed to power the MKS, Alter Products TXA10 microwave magnetron heads, however it may be used to power microwave magnetron heads from other manufacturers.
