Features include small size, high efficiency, low weight, and a good tolerance to total ionizing dose, single event effects, and environmental stresses such as temperature extremes, mechanical shock, and vibration. All components are fully derated to meet the requirements of EEE-INST-002 (NASA) and ECSS-Q- 30-11A (ESA). Extensive documentation including worst case analysis, radiation susceptibility, thermal analysis, stress analysis, and reliability analysis are available. The ML-Series converter has two outputs – one positive and one negative - each is independently regulated via linear post regulators. The outputs are sequenced during turn-on and turn-off such that negative output comes up first at turn-on and stays up at turn-off until the positive output has decreased. The ML-series converters incorporate a fixed frequency flyback power converter and internal EMI filter that meets the requirements for most major satellite power buses. The converter includes isolated On/Off telecommand with associated status telemetry. The converter also includes input under voltage shut-down functionality. Due to the linear post regulation of the outputs, the ML- Series is well suited for use in RF-applications where low noise, high output voltage accuracy, and high CS attenuation is required. Each converter is provided as a complete board assembly for installation into the host equipment chassis. The board is conformal coated (except for mating surfaces) and is mounted in the host chassis using screws. The board outline is L x W x H: 70mm x 50mm x 18mm. The weight is less than 50 grams. n Low Power RF Systems (like LNA) on-board Satellites Non-flight versions of the ML-Series converters are available for system development purposes. Variations in electrical specifications and screening to meet custom requirements can be accommodated. PD-97806 |
