Product features

高端音响变压器

01

HDV series: The iron core is rolled with a 0.23mm whole silicon steel sheet, and the nitrogen and hydrogen protective gas annealing is precisely controlled. The electrostatic shielding between the first stage is added. Compared with the conventional transformer, the electromagnetic interference is reduced by more than 50%;

02

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%;

03

HDB-GO series potting enclosure is not restricted by molds, and the external dimensions can be adjusted arbitrarily to meet the individual needs of customers; the central hole is fixed (an auxiliary locking edge hole can be added above 300VA) for easy installation;

04

The label is laser printed, simple and beautiful, and is the first choice for high-end audio manufacturers to purchase in batches. For user installation;

05

Fully hold UL, CE, RoHS, CESI, ISO9001 quality system certification.
