Frequently asked questions

The output voltage is DC 24V with an adjustment range of 24…28V. The factory setting is 24.1V, as mentioned in the 'Specifications' section of the viewed document.

The maximum output current is 20.0 A, but it can vary depending on the ambient temperature. At an ambient temperature below 55 °C (131 °F), it delivers 20.0 A. However, at 70 °C (158 °F), the output current derates to 12.5 A. The derating happens linearly between the temperatures of 55 °C and 70 °C.

Yes, this power supply has a hold-up time, which means it continues to provide regulated output voltage even when the input power is lost for a short period. The hold-up time depends on the output load, and it can be up to several seconds at no load. For example, at 24V and 10 A load, the typical hold-up time is 54 ms, and at 24V and 20 A load, it is 27 ms.
