         DW-xxSxx (S: single output) series and DW-xxDxx (D: dual output) series module power supply is a wide input voltage range, the output power 6W ~ 12W isolated DC-DC converter. Input voltage range commonly used specifications: 4.5~9.0V, 9~18V, 18~36V, 36~72V, 70~150VDC,; the output is divided into single (S), dual (D) two. High voltage regulation accuracy, high efficiency, high reliability, very low ripple and noise make it suitable for the distribution of power supply system of board supply. Mainly used in program-controlled switches, ATM switches, PBX, ISDN, cellular communication systems and so on.

       (2:1) Wide voltage input means that the input voltage can be allowed to vary within a wide specified range (e.g., 4.5~9.0V, 9~18V, 18~36VDC, etc.). Modular power supply with wide voltage input adopts PWM control mode, which is characterized by high power density, high output power and wide application range.

 
      Typical applications of DC-DC power modules (modular power supply), voltage polarity conversion, selection of external filter capacitors, overload and short-circuit protection circuits and series-parallel use are described in detail. Correct use can extend the service life of the product to avoid interference, overheating, self-excitation, poor start-up and other phenomena and irreparable damage.
