MTK series AC-DC converters are high-reliability DC converters designed primarily for aerospace electronic equipment. This power supply uses QRPFC+ dual-tube push-pull topology architecture, compatible with both AC and DC inputs, and can be externally controlled via isolated 485 communication for online software upgrades as needed. The housing is made of aerospace-grade aluminum and sealed with high thermal conductivity silicone, allowing it to operate normally in harsh environments, with a sustainable working temperature range of -45℃~100℃ (housing temperature). The innovative hexahedral metal packaging provides better anti-interference capability, and when combined with internal EMC filters, meets the GJB151B electromagnetic compatibility emission and conduction interference standards. This product complies with a wide range of military standards, with all internal components being domestically produced.
