Aegis Power Systems, Inc. has released new SWaP-optimized VME650-series power supplies to replace previous models, giving VME bus application developers in military and industrial markets, such as unmanned systems, more power. The new VME power supply units (PSUs) are high density power supplies for devices employing the standard 6U form factor.
By optimizing thermal management, the VME650 and VME650A offer significant improvements over previous models. “Various SWaP (size, weight, and power) initiatives across many markets drove the decision to offer more advanced VME power cards for our customers,” says senior engineer Matt Van Steen about the new Aegis Power Systems’ design. “We’re very pleased with the cost-effective results we achieved while significantly increasing maximum power output to 650W.”
Both units are pluggable power supply solutions with four outputs for a total of 650 watts. The VME650 and VME650A have keyed connectors which provide keying options when using multiple power supplies in one VME bus chassis. The primary differences between the two PSUs are cooling method, slot size, and weight. The VME650 is single-slot and conduction cooled via wedgelocks, while the VME650A is two-slot and air cooled.
The VME650 and VME650A are drop-in replacements for the existing VME550 and VME550A power cards, allowing customers to conveniently replace older units with the new modules.
