Leopard Power System

Complete Power System up to 1kW Output Power

Up to four Power Converter Channels, each with system characteristics to Resolve Dormancy issues:
• Active Transient Ride-through
• Input current limit
• Automatic Power sharing with defined voltage output characteristics without Internal Single point of Failure system share line
• Dual Input Capability

Targeted at EMC MIL-STD-461E or DEF-STAN 59-41

TRUE N +1 System Redundancy and Protection on Both Input and Output Terminals suitable for Battery Charging for Land Vehicles

Multi Channel Alarm Bite Monitors:
• Power Good on Output
• Over Voltage Protection
• Re-entrant Multi Alarm Thermal spreading Over Temperature protection at 105°C, i.e System reduces power when one channel stops but recommences power provision as soon as it cools down

• Ultimate System Mechanical Integrity using custom 40A Power Pin configuration

• Superior Shock Sustaining and Lowest weight Category using State of the Art Integrated Planar Magnetics
