APPLICATION
The K78Uxx-500R3 series high-efficiency switching regulators are ideally suited to replace LM78xx linear regulators and are pin compatible.
It has ultra wide input voltage range up to 90V dc, the efficiency up to 93% means that very little energy is wasted as heat so there is no need for any heatsinks with their additional space and mounting costs.
In addition to standard AC-DC and DC-DC power supplies, Mornsun also welcomes inquiries for custom applications. Many of the Mornsun DC-DC converters are 100% compatible with devices from some of the world’s larger manufacturers but at considerably more attractive prices.
