Current stability of the system can be increased by an order of
magnitude through application of the zero flux method of current
sensing. For the bipolar (dual-quadrant) mode high-stability magnet
power supply, the system consists of the Model 430 Programmer with
precision current sensing, one or more unipolar 08150PS Power
Supplies and Model 601 Energy Absorbers, and associated
interconnection cabling. The diagram on page 25 illustrates typical
interconnects for the integrated bipolar high-stability magnet supply
system.
Referring to the diagram on page 25, ensure the cabling is connected in
the following manner:
NOTE
The use of locking hardware is recommended for all high-current
connections.
CAUTION
Do not overtighten the hardware on the interconnection
terminals (refer to specifications table on page 8 for torque
limits). Overtightening can result in damage to the
terminals.
WARNING
Ensure the protective diode is installed across the output
terminals of the power supply with the anode at the
negative (–) terminal and the cathode at the positive (+)
terminal. Removal or omission of this protective diode may
cause serious injury to personnel and damage to the power
supply under loss of AC power conditions.
a. Connect
~ê
the Model 601 parallel hardware bus between Model 601
current terminals, plus-to-plus and minus-to-minus.
b. Connect
~è
the power supply parallel hardware bus between power
supply current terminals, plus-to-plus and minus-to-minus.
c. Connect the protective diode between the output bus bars of the
power supply: anode to the negative (–) terminal and the cathode to
the positive (+) terminal.
d. Connect the positive (+)
OUTPUT
bus
ì
of the power supply to the
positive (+) bus
~å
of the Model 601 Energy Absorber(s).
NOTE
When routing the magnet cable (+) from Model 601 negative (-)
bus through the current transducer (CT), the current-direction
arrow on the CT must point toward the magnet.
