Alter® CR 840 Compact, Air-cooled, Resonant Microwave Power Supply for 2kW, 2.45 GHz Magnetrons

The CR 840 magnetron power supply is a compact, air-cooled, switch-mode power supply designed to drive most nominal 2 kW @ 2.45 GHz magnetron models. 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.

Compact and lightweight form factor makes it ideal for installations where the space saving is critical
ON/OFF version is a highly competitive alternative to large & heavy, traditional L-C power supplies
High efficiency power supply design requires only air cooling for simple & low cost installation
Standard output ripple suitable for industrial heating applications
Stable filament control for in long magnetron life
Efficient power stage design results in very low harmonics and inrush current
