muRata UVQ-5/20-D24PB-C

For efficient, fully isolated DC power in the smallest space, UVQ series quarter bricks offer output voltages from 1.5 to 48 Volts with currents up to 40 Amps. UVQs operate over a wide temperature range (up to +70°C at 200 lfm airflow) at full-rated power. The optional mounting baseplate extends this to all practical temperature ranges at full power. UVQs achieve these impressive specifications while delivering excellent electrical performance. Overall noise is 35mVp-p (3.3V models) with fast step response (down to 50µsec). These converters offer high stability even with no load and tight output regulation. The unit is fully protected against input over and undervoltage, output overcurrent and short circuit. An on-board temperature sensor shuts down the converter if thermal limits are reached. Protection uses the “hiccup” (auto restart) method. A convenient remote On/Off control input operates by external digital logic, relay or transistor input. To compensate for longer wiring and to retain output voltage accuracy at the load, UVQs include a Sense input to dynamically correct for ohmic losses. A trim input may be connected to a user’s adjustment potentiometer or trim resistors for output voltage calibration closer than the standard accuracy. UVQs include industry-standard safety certifications and BASIC I/O insulation provides 2250 Volt input/output isolation. Radiation emission testing is performed to widely-accepted EMC standards. The UVQs may be considered as higher performance replacements for some USQ models.
