The product is C&D's flagship product, using high-frequency high-efficiency synchronous rectifier topology, with 1.2-15V output voltage and 6A output current, it can achieve -40℃ to +70℃ wide temperature range work, and has input undervoltage, overvoltage, reverse polarity, output overvoltage, output current limiting and continuous short circuit protection.
The UWR A‑Series offers single‑output DC/DC converters in a compact 1" × 2" package, delivering up to 6 A continuous current and up to 15 W power. Output voltages range from 1.2 V to 15 V, with input voltage options of 10‑18 V, 18‑36 V, or 36‑75 V. The converters achieve efficiencies up to 88 % and operate from –40 °C to +70 °C without heatsinks.
All models include input pi‑filters, undervoltage/overvoltage lockout, reverse‑polarity protection, output overvoltage protection, current limiting, and short‑circuit protection. Optional on/off control and output‑trim functions are available, and the devices are fully isolated (1500 Vdc) and UL/IEC certified.
