muRata UEE-3.3/45-D48PB-C

For efficient, fully isolated DC power in the smallest space, the UEE open frame DC-DC converter series fit in industry-standard “eighth brick” outline dimensions and mounting pins (on quarter-brick pinout) or surface mount option. Units are offered with a fixed output voltage and current up to 45 Amps. UEEs operate over a wide temperature range (up to +85 degrees Celsius at moderate airflow) with full rated power. Synchronous rectifier topology yields excellent efficiency. UEEs achieve these impressive mechanical and environmental specs while delivering excellent electrical performance in an industry standard DOSA compatible through-hole package or surface mount option. The unit is fully protected against input undervoltage, output overcurrent and short circuit. An on-board temperature sensor shuts down the converter if thermal limits are reached and automatically restarts the converter when the fault is removed. An On/Off control input enables phased startup and shutdown in multi-voltage applications. UEEs include a Sense input to correct for ohmic losses. A trim input may be connected to a user’s adjustment potentiometer or trim resistors for output voltage calibration. UEEs include industry-standard safety certifications and BASIC I/O insulation provides input/output isolation to 2250V. Radiation and conducted emission testing is performed to widely accepted EMC standards.
