Description
These single output DC/DC converters are designed to provide
a wide range of PCB mount power solutions. The wide 2:1
input voltage range covers the common American and
European telecom standards.
For flexibility, a trim pin is included to adjust the output
voltage. Use it to compensate for voltage drops in your
system鈥檚 wiring or to achieve non standard voltages. Use the
remote ON/OFF function to maximize battery life.
The NT Single Series continues the CALEX tradition of
reliable design by including transient overvoltage suppressor
diode protection at the output terminals. Also provided as
standard are overcurrent and overtemperature protection
circuits. These features assure zero failure rate operation
when using the NT Single Series. All CALEX products are
backed by a 5 Year Warranty.
