Standard rated power at 70°C:

PU2512 = 4W

PU3921 = 3W

PU5931 = 5W

For detail power value, please refer to Table 2.

RATED VOLTAGE

The DC or AC (rms) continuous working voltage

corresponding to the rated power is determined by

the following formula:

V =

)

(

PxR

Where

V = Continuous rated DC or

AC (rms) working voltage (V)

P = Rated power (W)

R = Resistance value (Ω)
