Frequently asked questions
Can I use the MDK200PC5 on a 230 V AC supply?
The manufacturer’s electrical table lists 100–240 V AC, while the product listing gives 100–200 V AC. Check the rating on the specific unit before using it at 230 V AC.
Is 40 A the input current or the output current?
It is the maximum DC output current. The specified output range is 0–40 A at 5 V DC.
What ripple limit does Rong Electric specify?
The main electrical table lists ripple and noise together at no more than 200 mV peak-to-peak. Voltage regulation is a separate specification of ±2%.
What happens if the output is shorted?
Rong Electric lists output short-circuit protection and current limiting for this model. The specification also identifies input undervoltage protection.
