B&K 1651A, 1652 instruction manual Operating Instructions

OPERATING INSTRUCTIONS___________________________________________________________________________

6.Make sure that the hook-up leads offer sufficient current capability and low resistance between the power supply and the circuits being powered. The hook-up leads supplied with the power supply are rated for 4 amps.

7.If the red OVERLOAD indicator lights, too much load has been placed on the supply. This will cause voltage and current to drop and prevent proper operation of the FIXED 5 V supply. To correct this situation, the load on the supply much be decreased so that no more than 4 amps of current are required.

NOTE

If decreasing the load does not cause the overload indicator to turn off, the overvoltage protection circuitry has turned on. In order to return the supply to normal operation, the output voltage must be decreased (or the external voltage source must be removed) and the power must be momentarily shut off.
