The output voltage is 25.5V at no load and decreases with increases in load, but this is not a problem at all for operation of IAI 24V controllers. Although the operation range differs between PSA-24 (204W) and PSA-24L (330W), the output voltage fluctuates within the range of the shaded area in both cases. The output voltage is cut off by the protection circuit if the overvoltage detection level is exceeded.
