Model 1790, 1791

High Current DC Power Supply

Models 1790/1791 are cost effective, high power, regulated DC

power supplies with 640 Watt output. They are linear high current

DC power supplies suitable for bench operation or standard 19" rack

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 &

1791 DC power supplies offer low noise output, so that power sup-

ply noise does not interfere with testing of telecom devices. The

1790 & 1791 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 equip-

ment, PBX system and DC to DC power supplies that provide power

to this equipment.

These well-regulated constant voltage/constant current supplies deliv-

er 0-32V at 0-20A (Model 1790) or 0-64V at 0-10A (Model

1791). They 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 nega-

tive 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. The 1790

and 1791 are designed to meet CE specifications and have superior

performance to comparable models costing 20 to 30% more.
