SunYuan technology development and production of energy meters dedicated 6KVAC high isolation anti-static DC/DC converter, is a high electrical isolation and anti-surge, anti-static characteristics, and the output of the output has a self-recovery overload and short-circuit and 8KV anti-static protection function of the national patent products (Patent No.: ZL 200420042857.1). Recently, this product has successfully passed the high isolation/anti-surge/anti-static test in the technical inspection related to the safety of the external RS485/RS232 interface of the power load management control terminal (user management terminal) instrument with high isolation (4500V) and anti-static (direct contact of the external terminal: 8000V). At present, it has been widely used in the power instrumentation manufacturing industry.

   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.
