The rectifier DPR 1200B-48V is a single phase, hot-pluggable, fan-cooled rectifier. The outstanding power density of this product offers the optimum 1U or 3U shelf solution for space critical applications. The constant output power characteristic supplies the specified power over the full output voltage range. The benefit is an optimised modular system design (fewer number of modules) and matches the supply requirements for state-of-the-art telecom equipment. These performances as well as the extended temperature range, wide input voltage range and advanced technology (patented solution) are the key factors of the success of this rectifier and it offers a cost effective and reliable solution.
The typical applications for this rectifier are both in indoor and outdoor environments, which is a perfect solution for digital subscriber line (DSL), transmission, PBX, wireless base stations, core network components, telecommunications networks and data networks. The rectifier meets the requirements set by the telecommunications standards.
