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 45 Amps. UEEs operate over a wide
temperature range (up to +85 degrees Celsius at
moderate airflow) with full rated power. Synchro-
nous 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.
