This triple output regulated DC power source is suitable for
general purpose laboratory and industrial applications. It
features adjustable and independent current limiting and
overvoltage crowbar protection for each output. A fault lamp
indicates crowbar operation or an overload condition.
The following description refers to the three outputs as
Source A (“A”), Source B ("B”) and Source C ("C”) respectively.
The power supplied by "A” and “B” is obtained from four
binding posts on the front panel. There is an internal
connection between the negative terminal of "A” and the
positive terminal of "B” when the TRACKING function is
engaged. In this mode the DC+ terminal on Source “A”
produces a positive voltage with respect to COMMON. The DC-
terminal on Source “B” produces a negative voltage with
respect to COMMON. When the TRACKING function is OFF, both
sources are isolated from each other.
A front panel TRACKING switch provides individual control of
each source or automatic Master/Slave operation. In this
mode source "B" tracks source “A”.
Source “C” provides power by means of two binding posts that
are isolated from ground. This source may be operated in
either polarity with respect to chassis or left floating.
All outputs may be operated simultaneously at full capacity
with no derating.
