Caution:
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.
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.
Caution:
Reference 3000's DC-DC power supply.
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.
