Model 1844 Beam Penetration

Replacement for Venus Scientific beam penetration power supply
DESC B54E0051-22 part number
Rapid switching between 8 kV to 17 kV
Used in flight simulators

Model 1844 powers beam penetration CRT's. It may be programmed to rapidly switch among any four voltage levels between 6 kV and 17 kV. Voltage levels are set by front panel trim adjustments. Applying 5-volt logic levels to the program inputs selects the preset voltages.

Model 1844 has four additional output voltages: a 3 kV focus, 16kV anode, -35 volt G1, and 525 volt G2 output.

Applications
Model 1844 is a legacy product that supports existing displays used for air traffic control and flight simulators. This product is equivalent to those formerly made by Venus Scientific and Eldec.
