This section provides general information on the operation of the NI PS-17
power supply.
The NI PS-17 can operate in series to increase the output voltage.
Figure 2-3 shows the NI PS-17 in a serial configuration.
Figure 2-3. NI PS-17 in Serial Operation
Before operating the NI PS-17 in a serial configuration, consider the
following:
• It is possible to connect as many units in series as needed, providing
the sum of the output voltage does not exceed 150 V
• Voltages with a potential above 60 V
more and can be dangerous. Such voltages must be installed with a
protection against touching.
• Use power supplies of the same type for serial operation.
• Earthing of the output is required when the sum of the output voltage
is above 60 V .
DC
• Keep an installation clearance of 15 mm (left/right) between two
power supplies and avoid installing the power supplies on top of each
other.
