Z28H50M500NNB is the standard 1/2 brick single circuit isolated voltage stabilizing output module, rated output voltage 50V, output current 10A.Peak efficiency can reach 96%, working temperature range is: - 55 ºC ~ + 100 ºC temperature (shell).
The technology of starting synchronous rectifier with leading pre-offset value improves the efficiency of power supply and the reliability of synchronous rectifier.
Active clamping absorption technology is adopted to reduce the voltage stress of power MOS tube and improve the reliability of power MOS tube.
The voltage feedback loop with no light coupling improves the response speed and stability of the loop.
The democratic current sharing method of master and slave modules is adopted to enable the energy modules to share current signals to complete the parallel application of automatic current sharing, which can be applied to the redundant backup system with high reliability.
Multilayer thick copper PCB and planar transformer are adopted to improve the power density of power supply.
The aluminum shell filling and sealing technology improves the power supply's ability to resist vibration, shock, salt spray and high temperature.
