Dcdc power module for electric vehicles, photovolt dcdc converter, direct flow 550v, straight flow 1500v
Product overview
The high-precision two-way direct current power source of the nd series is a two-way charger with a two-stage transformation structure with a high-precision, high reliability, programmability, automatic running direct-flow source, a high-precision and high-dynamic response characteristic of the direct-flow output and an automatic two-way running function, full-digit control, high-precision control, speed of response, wide range of output, programmability, with different controls。
Product characteristics
(1) internally sequestered transformer +lc direct flow filter, input output electrical separation。
(2) a two-stage conversion of the british fly above the pressure ig model group is used to isolate the power from the pure digital chemical frequency。
(3) energy can be returned to the grid: it has both power and load characteristics。
(4) the dcdc side uses a three-level/load wave transfer phase circuit to make the straight-flow output side more accurate and the texture smaller。
(5) capable of achieving the output's wideness, accuracy and dynamic responsiveness。
(6) the output has a constant pressure, a constant limit flow, a constant flow, a constant power, a constant resistance pattern。
