WRA_S-1WR2 & WRB_S-1WR2 series are isolated 1W DC-DC products with 2:1 input voltage and conventional voltage output. The product

has a relatively compact SIP-8 plastic package, and features high efficiency, operating temperature of -40 ℃~+85 ℃, remote control,

and continuous short-circuit protection. The smaller size and fine cost design make the converter an ideal solution in communication,

instruments, and industrial electronics applications.

Notes: ①Exceeding the maximum input voltage may cause permanent damage;

②

For the dual output modules, the capacitive loads of positive and negative outputs are the same.
