PANEL DESCRIPTION
CONNECTION AND OPERATION
q Connect the AC power cable of the PS-300 to an AC out-
let.
w Turn the PS-300 ON, then adjust the suitable output volt-
age.
• “ I ” : ON (Power indicator lights green)
• “O” : OFF (Power indicator goes off)
e Turn the PS-300 OFF, and make sure the equipment's
power is also OFF.
r Connect the DC power cable to the PS-300 and the
equipment's DC power input.
t Turn the PS-300 ON.
y Turn the equipment ON.
u To turn OFF the system, turn the equipment power OFF,
then the PS-300 in sequence.
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.
