Read MoreThe PRBX DBD150 Series AC/DC Power Supply is a compact and robust solution for industrial, defense, and railway applications. Delivering up to 150W of power, it ensures reliable and efficient performance in challenging environments.
Key features include a wide input voltage range (85–264V AC, 100–350V DC) with power factor correction (PFC) for energy efficiency and configurable output voltages (2–48V DC) to suit diverse application needs. The DBD150 Series incorporates advanced protection features, such as overvoltage, overcurrent, and thermal safeguards, as well as input over/undervoltage lockout, ensuring safe and dependable operation. Fully compliant with MIL-STD-810E for shock and vibration and MIL-STD-461E for EMI, it meets stringent requirements for durability and low electromagnetic interference.
Encased in a low-profile design, the power supply is engineered for extreme conditions, with operation supported up to +100°C baseplate temperature and an optional range from -40°C to +100°C. Its rugged construction includes options such as IP65 enclosure with MIL-38999 connectors for additional environmental protection.
The PRBX DBD150 Series AC/DC Power Supply is the perfect choice for dependable, efficient, and versatile power conversion in demanding conditions.
