Unipolar Supply with 610/630 Energy Absorber and Current Reversing Switch
2.5.4 Unipolar Supply with AMI Model 610/630 Energy Absorber
and Current Reversing Switch
For a simulated four quadrant power supply system with legacy AMI
hardware, the components include the Model 420, a unipolar power supply
(typically an AMI Model 10100 or 10200), an energy absorber / reversing
switch (an AMI Model 610 for 100 ampere applications or Model 630 for
200 ampere applications) and associated interconnecting cabling.
Figure 2-4 depicts the Model 10100 power supply used in conjunction with
the Model 610 Energy Absorber / Reversing Switch 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 / Reversing
Switch 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 (
−
) output lug of the power supply (6).
d. Connect the positive (+) output cable (7) of the Energy Absorber /
Reversing Switch 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 / Reversing
Switch.
