Product Description:
The LyzPower® series products is an isolated DC power supply product, which is used as a power supply for hydrogen production in electrolyzers.
Among them, LyzPower® xJ series products are AC bus input electrolyzer power supply; LyzPower® xZ series products are DC input and can be used for photovoltaic off-grid hydrogen product electrolyzer power supply. The product adopt SiC modules, which greatly improves the efficiency and power density, thereby reducing product volume.
It has a wide output DC voltage range (0-900VDC), which can applied in PEM or ALK electrolyzer.
Adopt SiC module technology, the maximum efficiency is as high as 98%;
High-frequency control, fast dynamic response, suitable for the application of PEM electrolyzer;
With built-in isolation transformer, safe and reliable;
Complete protection functions can ensure the safe and stable operation of the system;
Typical application:
Electrolytic hydrogen production power supply.
New energy simulated DC source.
