Applicable Hardware
The Model 420 has been designed to operate with a wide variety of switch
mode and linear power supplies from a variety of manufacturers. However,
not all compatible power supplies have been tested. The Model 420
Programmer has been tested and qualified with the following power
supplies:
AMI Model 12100PS switching power supply (12V @ 100A)
AMI Model 12200PS switching power supply (12V @ 200A)
AMI Model 7.5-140PS switching power supply (7.5V @ 140A)
AMI Model 10100PS switching power supply (10V @ 100A)
AMI Model 10200PS switching power supply (10V @ 200A)
AMI Model 4Q-05100 4-Quadrant switching power supply (±5V @ ±100A)
Xantrex Model XFR 12-100 switching power supply (12V @ 100 A)
Xantrex Model XFR 12-220 switching power supply (12V @ 220 A)
Xantrex Model XHR 7.5-130 switching power supply (7.5V @ 130 A)
Hewlett-Packard 6260B linear power supply (10V @ 100 A)
Kepco BOP 20-5M 4-Quadrant linear power supply (±20V @ ±5A)
Kepco BOP 20-10M 4-Quadrant linear power supply (±20V @ ±10A)
Consult with an AMI Technical Support Representative for other approved
power supplies.
General Precautions
Cryogen Safety
The two most common cryogenic liquids used in superconducting magnet
systems are nitrogen and helium. Both of these cryogens are extremely
cold at atmospheric pressure (
−
321°F and
−
452°F, respectively). The
following paragraphs outline safe handling precautions for these liquids.
Personnel handling cryogenic liquids should be thoroughly instructed and
trained as to the nature of the liquids. Training is essential to minimize
accidental spilling. Due to the low temperature of these materials, a
cryogen spilled on many objects or surfaces may damage the surface or
cause the object to shatter, often in an explosive manner.
Inert gases released into a confined or inadequately ventilated space can
displace sufficient oxygen to make the local atmosphere incapable of
sustaining life. Liquefied gases are potentially extreme suffocation
hazards since a small amount of liquid will vaporize and yield a very large
volume of oxygen-displacing gas. Always ensure the location where the
cryogen is used is well ventilated. Breathing air with insufficient oxygen
content may cause unconsciousness without warning. If a space is suspect,
purge the space completely with air and test before entry. If this is not
possible, wear a forced-air respirator and enter only with a co-worker
standing by wearing a forced-air respirator.
