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.
