The model 1672 is a quad display triple output regulated
DC power supply that provides one fixed output (5V/3A)
and two variable outputs (0-32V/ 0-3A) ratings. The variable
outputs can work independently, or in series tracking or
parallel mode.
Model 1672 offers exceptional performance and is an ideal
supply for Educational, Service and Maintenance, Hobbyist
and Manufacturing applications.
Model 1672 provides the user with many unique and useful
features not normally found in a triple output power at this
low price.
Model 1672 features four large, easy-to-read front-panel-
mounted 3-digit LED displays – one set reading volts and
amps of the "B" supply, the other set reads volts and amps
of the "A" supply. The unit has a unique variable tracking, B
track A at 5% to 100% capability.
