Operation

Redundancy Status

(Refer to Chart 1.)

Redundancy OK signal and LED will turn ON and light up when the input voltage difference is 2.4 V typ or less.

The signal and LED will detect the failure of a power supply on one side, or connecting errors of power supply

voltage.

Voltage Balance Status

(Refer to Chart 1.)

Balance LED will light up when the input voltage difference is 50 mV typ or less.

By adjusting the input voltage to light up LED, output current of each power supply will be balanced.

The lifetime as a power supply system will be more than twice comparing when there is only one power supply.

Applicable models: S8VK-G03005, S8VK-G06012, S8VK-G12024, S8VK-G240

@@, S8VK-G480@@

By adjusting the input voltage to light up LED, the fluctuation of the output voltage will be less when one of the

power supply breaks.

Reliability (MTBF)

Value

S8VK-R10: 720,000 hrs.

S8VK-R20: 680,000 hrs.

Definition

MTBF stands for Mean Time Between Failures, which is calculated according to the probability of accidental device

failures, and indicates reliability of devices.

Therefore, it does not necessarily represent a life of the product.

Life expectancy

10 yrs. Min.

Definition

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.
