2WR3 DC / DC series products provide small volume, high efficiency, small power, constant voltage, input isolation, non regulated, single output module power supply. This series of modules are specially designed for applications where a set of voltage isolated from the input power supply needs to be generated in the on-board power supply system. The product is suitable for pure digital circuit, general low-frequency analog circuit, relay driving circuit, data exchange circuit, etc.
Product Features
