*1. Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal
temperature of the Power Supply may result in ignition or burning.
*2. Refer to Engineering Data on page 8 for details.
*3. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than 10% of the voltage adjustment range. When adjusting
the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged. If the output voltage
exceeds 28.8 V, all branch outputs will be cut off.
*4. Rated input and output conditions: Rated input voltage, rated frequency, rated output voltage, rated total output current, and maximum cutoff
output current.
*5. 100% load conditions: Rated output voltage, rated total output current, and maximum cutoff output current.

Maintenance Forecast Monitor Function
Indication and Output
When the Product is purchased, “ful” will be displayed. As the
electrolytic capacitors deteriorate, the display will change to “hlf”
(Refer to Maintenance Forecast Monitor Function). “ful” will be
displayed for the maintenance forecast display for approximately one
month after the Power Supply is first turned ON. The accumulated
value will then be displayed depending on the ambient conditions.
(However, the “hlf” display may not appear, depending on the
application environment and the set value for maintenance forecast.)
If the maintenance forecast setting L (which can be set to 0.0 to 5.0
years in 0.5-year increments) is set to a value larger than two years,
the display automatically changes to a value (L - 0.5) after the
remaining time to maintenance is reduced to the set number of years,
and an alarm (A23) and the remaining time will be displayed
alternately.
If the setting is less than 2.0 years, the display changes to a value
(1.5) after the remaining time becomes less than two years, and after
the remaining time becomes less than the set time, an alarm (A23)
and the remaining time (L - 0.5) will be displayed alternately.
If the alarm (A23) and a numeric value are displayed alternately, the
transistor (maintenance forecast output terminal (Yrs)) will turn OFF
to indicate the need for maintenance., i.e., there will be no continuity
at the maintenance forecast output terminals.
(The LEF output will turn OFF when the maintenance time has been
reached.)
Example: Display When the Time Remaining to the
Maintenance Time Is Less Than 0.5 yr
1 2 3 4 5 6 V A Yrs °C s
1 2 3 4 5 6 V A Yrs °C s
Note: 1. The time remaining to maintenance is based on continuous
operation, not including the time when the power supply is
turned OFF.
2. “ful” will be displayed until approximately one month of
time has passed to enable estimating the speed of
deterioration. The output will remain ON (i.e., there will be
continuity at the maintenance forecast output terminal
(Yrs)).
3. For details on the display, refer to Relationship between
Displayed Values and Output of Set Values.
Maintenance Forecast Monitor Function
The Power Supply is equipped with electrolytic capacitors.
The electrolyte inside the electrolytic capacitors penetrates the
sealing rubber and evaporates as time passes after it is
manufactured. This causes deterioration of characteristics, such as
decreasing the capacitance.
Due to this deterioration of the characteristics of the electrolytic
capacitor, the Power Supply decreases its performance as time
passes.
The maintenance forecast monitor function shows an approximate
period left for maintenance of the Power Supply due to deterioration
of electrolytic capacitors. When the period left for maintenance that
the power supply forecasts reaches the set value, an alarm is
indicated and an output signal is triggered. Use this function to know
the approximate replacement timing of the Power Supply.
Note: The maintenance forecast monitor function indicates an
approximate period left for maintenance, based on
deterioration of the electrolytic capacitors. It does not predict
failures resulting from other causes.
