Product features

01

HDM series: high-quality iron core annealing, targeted design, electrostatic shielding between the first stage, compared with conventional transformers, electromagnetic interference is reduced by more than 20%;

02

HDV series: The iron core is rolled with a 0.23mm silicon steel sheet, which accurately controls the annealing of nitrogen and hydrogen protective gas, and adds electrostatic shielding between the first and second stages. Compared with conventional transformers, electromagnetic interference is reduced by more than 50%

03

HDB-GO series: using double shielding technology, 1.5mm thick iron shell epoxy overall potting, compared with conventional transformers, electromagnetic interference and electromagnetic noise are reduced by more than 90%;

04
