DQS1-S/DRS1-S DC-DC Converters

CUI Inc DQS1-S/DRS1-S DC-DC Converters are unregulated DC-DC converter modules housed in a compact 4-pin SIP package. These converters feature short circuit protection and 1W isolated output. The DQS1-S/DRS1-S DC-DC converters are UL/cUL 62368-1 certified. The DQS1-S converters offer 1000V_dc isolation voltage and the DRS1-S converters offer 2000V_dc isolation voltage. These converters are ideal solution for consumer electronics, digital or analog systems, smart home appliances, and small-scale automation applications.
