Depending on the model, power output can be variably adjusted from 10 to 100% using an external analog signal, a digital PWM signal, or with a simple digital ON-OFF signal. It is designed to power and control the TMx20 or TI020 microwave magnetron heads and also power other electrically compatible heads. The compact and innovative design of the CR 840 power supply makes it a highly competitive alternative to traditional, transformer based, power supplies. The CR 840 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. 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 CR 840 is enclosed in a lightweight and compact 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 power supply high voltage (HV) output, carrying the anodic current, is delivered through an HV connector.
