PRODUCT OVERVIEW
Wide range 4:1 inputs on the 1.50" x 1.90" x
0.38" converter are either 9 to 36 Volts DC (Q12
models) or 18 to 75 Volts DC (Q48 models), ideal
for battery-powered and telecom equipment.
Fixed output voltages from 3.3 VDC to 15 VDC are
regulated to within ±0.05% and may be trimmed
within ±10% of nominal output. Applications
include small instruments, computer-based
systems, data communications equipment, remote
sensor systems, vehicle and portable electronics.
The UEI 50-60W Series includes full magnetic
and optical isolation up to 2250 Volts DC (basic
insulation). For connection to digital systems, the
outputs offer fast settling to current step loads
and tolerance of higher capacitive loads. Excellent
ripple and noise specifications assure compatibil-
ity to circuits using CPU’s, ASIC’s, programmable
logic and FPGA’s. No minimum load is required.
For systems requiring controlled startup/shut-
down, an external switch, transistor or digital logic
may be used to activate the remote On/Off control.
Remote Sense inputs compensate for resistive line
drops at high currents.
A wealth of self-protection features avoid both
converter and external circuit problems. These
include input undervoltage lockout, input overvolt-
age and overtemperature shutdown. The outputs
current limit using the “hiccup” autorestart
technique and the outputs may be short-circuited
indefinitely. Additional features include output
overvoltage and reverse conduction elimination.
The synchronous rectifier forward topology
offers high efficiency for minimal heat buildup
and “no fan” operation. The open frame design is
also available under special quantity order with
an encapsulation shell and thermally-conductive
potting compound. This option offers additional
cooling in low-airflow, high temperature applica-
tions.
