ASTEC STANDARD POWER DC/DC Converters The ML Series is ideally suited for applications in telecommuni- cations, distributed power systems, automatic test equip- ment, geosource test equipment, and process control requiring small size and high efficiency. Special Features - MOSFET design Surface mount technology 4:1 ultra-wide input range Continuous foldback short circuit protection Regulated outputs 500 Vdc I/O isolation Efficiency 80% (typ) The new ML Series features SMT technology and the latest in state-of-the-art MOSFET design. Utilizing both technologies has enabled our design engineers to reduce the unit surface area by 50% over competitive products with similar power levels. Features include 4:1 ultra-wide input range, efficiencies to 80%, continuous short circuit protec- tion with auto restart, input/ output isolation of 500 Vdc, and an operating temperature range of -25C to +71C. Ail models are packaged in a six-sided shielded case measuring 1.0" X 2.0" X 0.4" high. e e e e e e e e e WbE D MM 1013122 0000630 315 MHPUR ML Series 6 Watts Single/Dual Outputs GYD) ASTEC V-S7-\\ | MLD-3050-9 Electrical Specifications .
