PULSE OPERATION DURABLITY
1 = RST30- B2X, B2Y, B4Z
2 = RST25-B4X, B4Y (one resistor)
The figure illustrating pulse load shows the safe operation area, which measured
experimentally and which can operate with a rectangle pulse of a long cycle. However,
data does not guarantee the operation about the continuous pulse load of a short cycle in
which a resistor carries out a temperature rise with average electric power. Pulse peak
power recommends operating within the rated electric power. Pulse operation of models
RST60-B2X, B2Y, B4Z are the same as models RST30- B2X, B2Y, B4Z.
Pulse Peak Power (Watts)
NOTES
For RST60-A4X and RST90-A4Z
When water cooled heat sink is used, maintaining a flange temperature of 25°C is difficult.
When the flange temperature is over 25°C, the rating will be decreased as illustrated in
the derating curve. In short pulse applications, the peak power can not exceed over
600W.
