Description
The rectifier DPR 1200B-48 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 optimized modular system design (less number of modules) that matches the supply
requirements for state-of-the-art telecom equipment These features as well as the wide input voltage range,
and low input current distortion are the key factor of the success of this product and it offers a cost effective
and reliable solution.
