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.
PRODUCT OVERVIEW
Units are offered with a fixed output voltage and
current up to 30 Amps. UEEs operate over a wide
temperature range (up to +85 degrees Celsius at
moderate airflow) with full rated power. Interleaved
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 certifi-
cations and BASIC I/O insulation provides input/
output isolation to 2250V. Radiation and conducted
emission testing is performed to widely accepted
EMC standards.
