The ENI Model OEM-25B Power Generator is totally solid state. This generator is a water-cooled power source expressly designed for use in gas plasma and sputtering applications. Completely self-contained, the OEM-25B provides all of the control and monitoring functions needed in a state-of-the-art power generator. It will provide power output of 2500 W into a 50 impedance.
The reliable operation of any solid-state power generator is directly influenced by the sophistication of its power control circuitry. The OEM-25B automatic power control module measures forward RF power, reflected RF power, and the current drawn by each RF power amplifier section. Should any of these parameters exceed a preset limit, the automatic power control will immediately limit RF output power so that the components always remain within their safe operating limits.
Besides assuring safe operation, the OEM-25B's automatic power control module provides constant RF output power to within +/-2% of the command power setting above 200 W or +/-4 W below 200 W into VSWRs up to 3:1. Automatic power control also eliminates power output drift due to line voltage variations, component aging, and reduces output hum and ripple to insignificant levels.
The OEM-25B is provided with two interface connectors. One connector provides simple analog control and monitoring of the generator through the use of voltage levels and TTL-compatible signals. The other connector provides full digital remote control of the generator using a simple protocol on an RS-232 or RS-422 serial link.
Reliable, continuous performance of the OEM-25B is ensured with the use of conservatively rated solid-state components and automatic power control. Plug-in modules are easily removed for replacement or repair should service be required. Only minimum maintenance is required to guarantee successful operation and endurance of your generator. When compared with vacuum tube equipment, greatly
reduced DC voltages used in the OEM-25B greatly reduce potential hazards associated with servicing.
