Modification of Cober Electronics System 2000
Initial Problem
The original design of this system placed the microwave power supplies, magnetron tubes, and waveguides in a single enclosure mounted directly to the oven cavity. These power supplies have since become obsolete and are no longer supported or available.
All internal components were air-cooled, and during warm summer months, some customers experienced thermal issues, struggling to keep the system enclosure within safe operating temperatures. This led to overheating risks, system instability, and maintenance challenges.
Objective
-
Replace obsolete power supplies with new, supportable models using U.S.-made components.
-
Relocate sensitive power and control hardware to a thermally stable environment.
-
Improve long-term serviceability and component availability.
-
Extend system life and ensure reliable operation year-round.
MES Solution
-
Removed all original power supplies from the oven-mounted enclosure.
-
Installed a free-standing, air-conditioned enclosure near the system to house the new power supplies, controls, and metering hardware.
-
Routed new control wiring, as well as high-voltage and filament wiring, from the new enclosure through sealtight conduit to the original system.
-
Interfaced all new connections properly with the existing oven hardware.
-
Tested the complete system to ensure correct operation and stability.
Results
-
Restored the integrity and operational reliability of the system.
-
Resolved historical thermal management issues during hot weather.
-
Ensured continued serviceability with readily available U.S.-made components.
-
Extended the system’s usable life by modernizing the power infrastructure.
