INSTALLATION GUIDE FOR THE
DC-DC POWER CONVERTERS
INTRODUCTION
The NTI DC-DC Power Converters convert power from a 24 or 48VDC voltage source (see chart next page) to power many DC
powered devices with various current requirements.
Features:
External DC-DC converter
Used to install NTI products in a Telecom environment
Accepts DC Voltage (see chart)
3-position screw-terminal connection
Accepts positive or negative polarity
3-pole detachable screw terminal for connecting input voltage
2.1x5.5mm male DC power jack for output
Includes a 3-foot female-to-female DC power cable
RoHS compliant
INSTALLATION
Mount the DC-DC Power Converter using the slots in the
mounting ears.
CONNECTION
Note: To prevent damage to the voltage source or the power
converter proper polarity must be observed when making
connections.
Connect a power source
using 16-24AWG stranded wire (select
wire size dependant upon your power requirements)
to the “+“ ,
“-“ and “
“
(
earth ground
)
connections via the removable
terminal block. Use the chart on the next page (“Input Range”)
to determine the voltage that can be connected to the INPUT
terminals on the power converter.
Note: The wire connection terminal block is easily removed
from the power converter for convenient wire termination.
Connect the 3 foot female-to-female DC power cable
(supplied) between the “Output” port on the power
converter and a device to be powered. Use the chart on
page 2 (“Maximum Current”) to determine the maximum
load that can be placed on the power converter.
