en.Wedoany.com Reported - MicroPower Direct (MPD) has introduced two high-isolation encapsulated AC/DC power modules, the MPM-100SVI and MPM-150SVI, delivering 100W and 150W respectively. They feature a universal input of 90-264 VAC, a compact fully encapsulated structure, 4300 VAC isolation, and an operating temperature range of -40°C to +85°C. These models are suitable for robotics, autonomous systems, and motion control designs where isolation performance and thermal margin are critical.
Power supply selection for mobile robots and autonomous platforms involves various trade-offs that can challenge traditional industrial power modules. Motor drives, servo controllers, and actuators generate significant electrical noise on shared power rails, making high input-to-output isolation essential for protecting sensitive computing, sensor, and communication electronics. The MPM-100SVI and MPM-150SVI offer an isolation rating of 4300 VAC, providing higher isolation than many comparable encapsulated modules, offering additional margin for designs where isolation integrity is a system-level safety or reliability requirement. The -40°C to +85°C operating range exceeds the typical +70°C rating of similar encapsulated modules, supporting deployment in outdoor, vehicle-mounted, and variable environment applications.
Both models operate over a universal 90-264 VAC input range and accept a DC input of 127 to 370 VDC, providing flexibility for designs powered by AC mains or rectified DC buses. Output voltage options are 12V, 24V, and 48V, covering the main voltage rails used in robotics and autonomous system architectures. Full-load efficiency reaches 93.5%, an important consideration for battery-powered or thermally constrained platforms. The operating temperature range is -40°C to +85°C with free air convection. Both models are UL/cUL 62368-1 certified, carry CE, UKCA, CA, and RoHS markings, and meet CISPR/EN 55032 Class B radiated and conducted emission requirements. MTBF (Mean Time Between Failures) exceeds 250 kHours, based on MIL-HDBK-217F standards.
Target applications include mobile and fixed robotic platforms, autonomous guided vehicles and mobile robots, industrial motion control and servo drive systems, autonomous inspection and logistics equipment, as well as drone ground support and charging infrastructure.
"Engineers designing high-power embedded systems tell us they need encapsulated AC/DC solutions that can handle platform isolation and reliability requirements without compromising isolation performance, reliability, or thermal capability," said Amy Anahory, CEO of MicroPower Direct. "The MPM-100SVI and MPM-150SVI are designed precisely for this environment—compact, fully encapsulated, and rated to meet the wide temperature and isolation requirements needed for robotics and autonomous system designs."
The MPM-100SVI and MPM-150SVI are now available through MicroPower Direct and Digi-Key. Both models are offered with 12V, 24V, and 48V output voltages.
