53509 Series PRELIMINARY SOLID STATE POWER CONTROLLERS MICROPAC MICROCIRCUITS PRODUCTS DIVISION Mii Features: • 28V, 15A Operation • Power MOSFET with Low On-State Resistance • Controlled Soft Turn-On • I²t Overload Protection • Short Circuit protection • External Trip Profile Programming (30% to 100% of Rating) • Fault and Output State Monitor • Isolation to 1000V • Military environmental screening available DESCRIPTION Applications: • • • • Designed for 28V bus application Aircraft Power Distribution Military/High Reliability Systems Satellite/Space Systems The 53509 Series Solid-State Power Controllers are lightweight and resistant to damage from shock and vibration. They are designed to replace electromechanical breakers and solid-state relays. They overcome the problems associated with arcing and contamination of breakers as well as providing internal protection for overload and short circuit conditions. They provide Fault and Output State monitoring as well as a controlled Soft Turn-On. The Trip Profile is externally Programmable from 30% to 100% of Rating Optical coupling between the input and output stages provide effective isolation of 1000VDC. The Power MOSFET Switches used in the output stage provide low “on” resistance, low offset and minimal internal power dissipation. Precautions: Precautions must be taken to limit the transient voltages generated by the inductance in the system wiring and load when a Overload condition causes the SSPC to turn off. When testing individual SSPC’s, care should be taken to simulate actual system conditions.
