High Current DC Power Supplies
Models 1790, 1791, 1794
1795 & 1796
Models 1790’s are cost effective, high power, regulated DC power
supplies with high power. Suitable for bench operation or
standard operation. These linear power supplies are high power
workhorses that will easily deliver clean power to your
high-current circuits.
Ideal for telecom application
Since noise elimination is critical for telecom application, the 1790
series DC power supplies offer low noise output, so that the
power supply does not interfere with testing of telecom devices.
These 1790’s are ideal for manufacturers who build equipment for
telecom industry that operates from 48V or higher DC rail such as
base stations, switches, public and private telecom network

equipment, PBX system and DC to DC power supplies that provide
power to this equipment.
These well-regulated constant voltage/constant current supplies
can be adjusted continuously throughout the output range by front
panel controls. The units will automatically cross over from
constant voltage to constant current mode and vice-versa if the
output exceeds preset limits. Front panel LED meters are provided
for monitoring voltage and current. The load terminals and remote
sense terminals are located on the front panel. Either the positive
or negative output terminal may be grounded or floated up to a
maximum of ±300VDC above ground.
Special features include the ability to set constant current with no
load and remote sense to compensate for any wire loss. These
power supplies have superior performance to comparable models
costing 20 to 30% more.
