The new QB8-Mark II and QB4-Mark II units, now
available in US, EU and Australian versions, provide
all of the elements and benefits of the original
QBASE with several marked improvements:
• Connectors: The IEC input and the US (NEMA) and EU
(Schuko) connectors have been upgraded to new, more
durable connectors that maintain better connectivity
after extended use.
• Frame Plate: There is now a customized “frame plate”
housing for the connectors which improves upon the
mechanical stability of the device as a whole.
• PC Board: The new QB8-Mark II and QB4-Mark II have
enhanced PC boards that have been upgraded to
include heavier traces, designed to accommodate
higher currents.
• Dedicated Fuse: All QB8 and QB4-Mark IIs now have a
dedicated fuse installed, providing overcurrent
protection of the source circuit and preventing system
damage caused by overheating.
• Feet: The redesign of the QBASE model has four fixed
stabilizing feet that have greater contact surface and a
wider stance to provide stability on hard surfaces. |
