DQM1-S DC-DC Converters

CUI Inc DQM1-S DC-DC Converters are 1W isolated converters that feature 3000V_DC isolation voltage for enhanced safety and noise immunity. These converters offer single and dual regulated outputs with a wide input voltage ranging from 2.97V_DC to 26.4V_DC. The DQM1-S converters operate over a temperature range of -40°C to 105°C and comply with IEC/EN 62368‑1 safety standards. These converters come in a compact industry‑standard SIP package, making them suitable for space‑constrained designs. The DQM1-S DC-DC converters are ideal for industrial, IoT, and telecommunication applications.
