S8VK-X

Peak Hold Current

The output current maximum value is stored as the peak hold current.
(5 ms average value)
Measurement is not performed for approximately 3 seconds
immediately after the input power is turned ON.

Peak Hold Curmrent Reset

When the peak hold current is displayed, it can be reset by pressing
the Reset key for 3 seconds or more.

Note:

For types without an indication monitor, it is not possible to
reset the peak hold current via reset key operation.

Replacement Time Calculation Function

This 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, this Power Supply decreases its performance
as time passes. The replacement time calculation function calculates
an approximate period left for maintenance of this Power Supply due
to deterioration of electrolytic capacitors. Use this function to know the
approximate replacement time of the Power Supply.

Note:

The replacement time calculation function indicates an
approximate period left for maintenance, based on
deterioration of the electrolytic capacitors. It does not predict
failures resulting from other causes.

Principle of Operation

The deterioration speed of the electrolytic capacitors varies
considerably with the ambient temperature. (Generally the speed
follows the Arrhenius Law, i.e., for every 10°C increase in the
temperature, the rate of degradation doubles.) The S8VK-X monitors
the temperature inside the Power Supply, and calculates the amount
of deterioration according to the running hours and internal
temperature.

Note: 1.

Due to degradation of internal electronic parts, replace the
Power Supply approximately 15 years after purchase even
if the replacement time calculation for years and percentage
do not appear.

The replacement time is accelerated or decelerated
according to operating conditions. Periodically check
indication.

The accuracy of the replacement time calculation function
will be reduced in applications where the input power turns
ON and OFF frequently.

Years until replacement

(Indication monitor)

is indicated at the time of purchase (when initially powered on),

and continues to be indicated for approximately one month.
Afterward, the state of deterioration for the electrolytic capacitor is
calculated based on the usage environment, and

is indicated

when deterioration progresses. When the years until replacement
reaches 5 years or less, it is indicated in 0.1 step increments within
the range of 4.9 to 0.0. (Depending on the usage environment, the
number of years may be indicated after

without

being

indicated.)
(Communication)
Communication is calculated in 0.1 step increments within a range of
15.0 to 0.0.

Note:

The number of years until replacement may vary if there are
frequent load variations or in locations where the ambient
temperature fluctuates drastically.

Percentage until replacement

With the number of years until replacement at the time of manufacture
set as 100%, as deterioration of the electrolytic capacitor progresses
through use, it decreases in 0.1% step increments.
