Maintenance Forecast Monitor Function
The Power Supply is equipped with electrolytic capacitors.
The electrolyte inside the electrolytic capacitor penetrates the sealing
rubber and evaporates as time passes since it is manufactured, which
causes deterioration of characteristics such as decreasing the
capacitance, etc.
Due to this deterioration of the characteristics of the electrolytic
capacitor, the Power Supply decreases its performance as time
passes.
Relationship between Indicated Values and Output of Set Values
Principle of Operation
The deterioration speed of the electrolytic capacitor varies
considerably according to the ambient temperature. (Generally the
speed follows “Rule of Two for every 10°C”; for every 10°C increase
in temperature the rate of degradation doubles according to
Arrhenius’s equation.) The S8VS-@@@24A@@ monitors the
temperature inside the power supply, and calculates the amount of
deterioration according to the running hours and inside temperature.
Judging by this amount of deterioration, the power supply will give the
alarm indication and output when the period left for maintenance
reaches the set value.

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.

MTBF stands for Mean Time

calculated according to the
probability of accidental device
failures, and indicates reliability of
devices.
Therefore, it does not necessarily
represent the life of the Product.
The life expectancy indicates
average operating hours under the
ambient temperature of 40°C and a
load rate of 50%. Normally this is
determined by the life expectancy of
the built-in aluminum electrolytic
capacitor.
