Model 1730-12-12-2
The Model 1730-12-12-2 dc-to-dc converter provides a regulated and well-filtered 13.6-Vdc output from 12-Vdc
battery systems. This output is galvanically isolated from the source and chassis and, therefore, may be connected
either as a positive or a negative output. Designed to perform equally well in mobile and stationary applications,
these converters can be used to operate low-power radio transceivers, data modems and other sensitive electronic
loads.
SPECIFICATONS
Input Voltage Range
9 Vdc to 18 Vdc
Output Voltage and Current
13.6 Vdc @ 2 amperes (continuous duty @ maximum rated
ambient temperature)
Output Voltage Regulation
Versus line: ±0.5%
Versus load: ±0.5%
Output Voltage Ripple
Typically less than 10 mV rms and 100 mV peak-to-peak
Protection
Protection against overloads and load short circuits is
provided electronically. Recovery to normal operating
conditions is automatic upon removal of an overload or shortcircuit fault.
Protection against accidental reversal of the dc input-voltage
polarity during installation is provided by a shunt diode
working in conjunction with a user-supplied input fuse or
circuit breaker. See section titled “Installation”.
Isolation
Isolation capable of passing a 2000-Vdc stress test is
provided between the input and output and between the input
and chassis.
The output is galvanically isolated from the chassis (100 Vdc
stress test rating).
Input/Output Connections
The input and output connections are provided via heavyduty barrier-strip terminal blocks. The terminal-block screws
accept lugs for use with #6 hardware.
Ambient Temperature Range
-40°C to +70°C (-40°F to +158°F) with convection cooling
Installation
Good installation practice for electronic equipment operated
from a battery source dictates that input fuses or circuit
breakers should be located at the battery end of the cables
feeding the converter. For this reason, no protection devices
are built inside the Model 1730-12-12-2 to protect against
fault conditions at the input to the converter. Instead, the
input line should be externally fused at 10 amperes.
Mechanical
Dimensions are 1.7"h x 5.3"w x 7.7"d (excluding terminal
blocks). Baseplate mounting holes accept #10 hardware on
a 4.9" x 4.9" pattern.
Weight is approximately 1.3 pounds.
