OVERLOAD AND SHORT CIRCUIT PROTECTOR

The PS-300 has overload and short circuit protection circuits.
When the PS-300 is under the condition of overload or the +
and _ lines are shorted, the PS-300 limits the output current
and the overload indicator lights red. In such a case, turn OFF
the PS-300, remove the source of the problem, wait several
seconds, then turn it ON again.
