When a battery is deeply discharged, it will initially draw a very large charging current and thus,
will force the power supply into current limit mode for prolonged periods. This is harmful for
the power supply.
The charge limiting resistor will limit the charging current, thereby, ensuring that the maximum
charging current is well below the current limit value of the power supply.
It is recommended that optional battery back-up module may be used to convert S-23-13.8V for
battery back-up application.
TROUBLESHOOTING
PROBLEM: Power ON/OFF switch does not illuminate when turned on.
PROBABLE CAUSE:
No power in the AC outlet: AC side fuse inside the power is blown
SUGGESTED REMEDY:
Check there is power in the outlet: replace the fuse inside the unit.
PROBLEM: AC side fuse blows as soon as power is turned on.
PROBABLE CAUSE:
Unit is defective
SUGGESTED REMEDY:
Call Tech support
PROBLEM: The output voltage is 0 V or very low.
PROBABLE CAUSE:
Input voltage is very low; the unit is in current limit condition due to overload caused
by large reactive loading or by the output being short circuited
