Q: Can this power supply be used in parallel for higher current?
A: The SD series is designed for single-unit operation. For higher current requirements, we recommend using a higher wattage model.
Q: Is there a DC OK signal for remote monitoring?
A: Yes, the green LED indicator shows DC OK status. For remote monitoring, please check our SDseries with relay output.
Q: What is the derating curve above 50°C?
A: The output current derates linearly from 100% at +50°C to 50% at +70°C .
Q: Does it support both AC and DC input?
A: Yes, it accepts both AC (85–264V) and DC (90–375V) input, making it versatile for different power systems .

1. All parameters NOT specially mentioned are measured at 12,24,48VDC input, rated load and 25℃ of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. | |||||||||
