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