6.12 Generating
higher voltages
Since the AC voltages sent out from Sverker are
separated from each other and from the mains,
series connections can be made. In such case,
however, it is important to keep the following in
mind:
• Make certain that no insulation voltage limits
are exceeded.
• Do not exceed the insulation voltage of the
connected voltmeter.
• Always comply with the applicable safety
regulations.
6.11 Obtaining the
correct phase angle
when two or more AC
outputs are being
used
Three separate AC voltages can be obtained from
Sverker:
• 0-250 V AC output from the current source.
• 0-120 V AC voltage source.
• 0-100 A, 0-40 A and 0-10 A current outputs
(from different taps on the same winding).
If these are connected to a common point, it’s
important to know the polarity. The right-hand
terminal in each of the outputs is thus provided with
a black dot, thereby indicating that these output
socket terminals have the same polarity.
