Luso Electronics, UK distributor of high input voltage power supplies manufactured by EFORE, announces availability of EFORE’s ROAL-branded DDP400 high efficiency AC-DC sealed power module. With its high efficiency, small form factor and convection or conduction cooling capability, the sealed power supply is ideal for digital outdoor displays, LED lighting, and industrial control or clean room equipment where fan noise or moving air is not acceptable.
By converting energy at a typical 94% efficiency, the DDP400 module generates less heat facilitating thermal management in space constrained environments, resulting in very high reliability.
Delivering a steady 400W of regulated DC power through the full 90 to 264V AC input range, the compact DDP400 module is 20% smaller than competing 300W modules enabling designers to integrate it into 1U applications.
Besides its small form factor (83.05mm x 211.84mm x 41.91mm), the sealed IP67 rated package ensures protection against dust and water immersion up to 1m for up to 30 minutes, and can be installed in contact with thermo-conductive part of the system so to transfer heat by conduction, therefore, enhancing performances.
The DDP series is available in four standard output voltages: 12, 24, 36, 48V DC, offering an auxiliary 12V DC and a stand-by 5V DC outputs.
When conduction cooled, or convection cooled with its optional heat sink assembly, the module can deliver full output power from -20 to 50 °C. It can operate up to 70 °C with de-rating and -30 °C. Protection features include fuse on each AC lines, input under-voltage lockout, output over-current, output short-circuit, output over-voltage and over-temperature.
The MDP400, a sister product of the DDP400 is aimed at medical lighting and power applications with full compliance with UL/IEC safety standards for medical equipment.
The DDP400 is also available in four other compact packages to fit other design applications: open frame, u-chassis, chassis with top fan and chassis with front fan.
