2.5.3 Unipolar Supply with AMI Model 600/620 Energy Absorber
When the Model 420 is used in the dual quadrant mode with legacy AMI
hardware, the magnet power supply system consists of the Model 420, a
unipolar power supply (typically an AMI Model 10100 or 10200), an energy
absorber (an AMI Model 600 for 100 ampere applications or Model 620 for
200 ampere applications) and associated interconnecting cabling.
Figure 2-2 depicts the Model 10100 power supply used in conjunction with
the Model 600 Energy Absorber and ancillary components.
Connect the cabling in the following manner:
a. Connect the positive (POS) output terminal (1) of the power supply
to the positive (+) input cable (2) of the Energy Absorber using 1/4-
20 or similar hardware.
Note
The use of locking hardware is recommended for all high current
connections.
Warning
Ensure the protective diode remains installed across the output
terminals of the power supply with the anode at the
1(* ative
terminal and the cathode at the 326 itive terminal. Removal of this
protective diode may cause serious injury to personnel and damage
to the power supply under certain loss of power conditions.
b. Connect the negative (
−
) input cable (3) of the Energy Absorber to
the positive (+) shunt terminal (4) of the Model 420.
Caution
Do not overtighten the nuts on the current shunt terminals of the
Model 420 (see the torque specifications on page 7). Overtightening
can result in damage to the terminals.
c. Connect the negative (
−
) shunt terminal (5) of the Model 420 to the
negative (NEG) output lug of the power supply (6).
d. Connect the positive (+) output cable (7) of the Energy Absorber to
the positive (+) vapor-cooled current lead (8).
e. Connect the negative (
−
) vapor-cooled current lead (9) to the
negative (
−
) output cable (10) of the Energy Absorber.
