6.1 Output current monitor

PBA300F, 600F, 1000F, 1500F

It is possible to know the output current to measure the voltage

between CB to -S in CN1 or CN2.

The relation between CB voltage and load current is shown in

Fig.6.1.

Remarks :

Fig.6.1 is nominally, not guarantee.

Please ask to us if the characteristic of the other model is neces-

sary.

Note the following when you measure the voltage of CB terminal.

Please note wiring so as not to malfunction because of the

noise.

Please use the input impedance of measurement equipment

must be 500k

or more.

Please note internal parts might be damaged when CB terminal

and -S terminal are short circuit.

Derating curve depending on input voltage of PBA1500F is shown

in Fig.5.3.

5.3 Expectancy life and warranty

Expectancy life

The expectancy life is as follows.

PBA300F, 600F, 1000F, 1500F

Regular exchange is necessary for the fan, because the life ex-

pectancy (R (t) =90%) of the fan depending on the use condition

is shown in Fig.5.4.

Warranty

PBA50 - 150F :

The warranty is 5 years when average ambient temperature of

year is Ta=40

or less and load factor is average 50% or less.

However, the warranty is 3 years when average ambient tempera-

ture of year is Ta=50

or less and load factor is series 100%.

PBA300 - 1500F :

The warranty is 5 years if it is derating curve.
