While a Reference 3000 may work with other power sources, we cannot guarantee it will work to its full
specifications. If you have to use the Reference 3000 with a different supply, make sure that the supply is
regulated, has an output between 22 and 26 V and supplies at least 5 A of load current. Inrush current drawn
by the Reference 3000 at “power on” has been known to cause improper operation of an external power
supply, even though the supply is rated for more than 5 A of output current.
Power Switch
The
Power
switch is located just below the
Power In
jack. It switches the power from this jack to the input of
the Reference 3000’s DC-DC converter.
Caution:
Power input voltages less than 20 V or greater than 32 V can damage the
Reference 3000’s DC-DC power supply.
Caution:
If your facility owns both Reference 600’s and Reference 3000’s, you must
insure that the smaller power adapter from the Reference 600 is
not
used to power a Reference 3000. The
Reference 3000 will not power up with the smaller adapter. Fortunately, neither the Reference 3000 nor
the small power adapter will be damaged if connected in error.
