AMI MODEL 601 ENERGY ABSORBER
INSTALLATION, OPERATION, AND
MAINTENANCE INSTRUCTIONS
I.
INTRODUCTION
The AMI Model 601 Energy Absorber is designed to provide a compact, fast-rampdown
option of up to 5 VDC for AMI power supply systems. The Model 601 is designed to
operate safely in the event of loss of facility AC power by drawing the necessary power
for internal cooling from the superconducting magnet. Upon loss of AC power to a
power supply system, the Model 601 will ramp the system to zero current at a
discharge rate of approximately 5 VDC.
