Certifi ed to UL/EN/IEC 60950-1, CAN/CSA-C22.2
No. 60950-1, 2nd Edition, safety approvals and
EN55022/CISPR22 standards
Pre-bias operation for startup protection
The UWE series open frame DC-DC converters
deliver up to 120 Watts in an industry-standard
“eighth-brick” through-hole package. This format
can plug directly into quarter-brick pin outs.
Several standard fi xed-output voltages from 3.3
Vdc to 12 Vdc assure compatibility in embedded
equipment, CPU cards and instrument subsystems.
The extended 4-to-1 input voltage range is ideal for
battery-powered, telecom or portable applications.
Very high effi ciency means no fans or tempera-
ture deratings in many applications. An optional
baseplate extends operation into most conceivable
environments.
The synchronous rectifi er design uses the maxi-
mum available duty cycle for greatest effi ciency
and low power dissipation. These devices deliver
low output noise, tight line/load regulation, stable
no-load operation and fast load step response. All
units are precision assembled in a highly auto-
mated facility with ISO-traceable manufacturing
quality standards. Isolation of 2250 Volts assures
safety and fully differential (fl oating) operation for
greatest application fl exibility. On-board Sense
terminals compensate for load line voltage errors at
high output currents. Outputs are trimmable within
±10% of nominal voltage.
A wealth of protection features prevents damage
to both the converter and outside circuits. Inputs
are protected from under voltage and outputs fea-
ture short circuit protection, over current and over
temperature shut down. Overloads automatically
recover using the “hiccup” technique upon fault
removal. The UWE is certifi ed to standard safety
and EMI/RFI approvals. All units meet RoHS-6
hazardous materials compliance.
