Frequently Asked Questions
1. What is the output of MQ300PC4.5?
The product information lists 4.5V output with a 60A current capacity.
2. What AC input is listed for MQ300PC4.5?
The listed input is 100–240Vac, 50/60Hz, with a maximum input current of 5.0A.
3. Does the model name confirm a 300W output?
Use the documented electrical ratings rather than deriving a power rating from the model name. This page lists the confirmed voltage and current without assigning an unverified wattage.
4. Can MQ300PC4.5 replace a 5V LED power supply?
Check the LED modules’ accepted voltage first. The listed output is 4.5V, so a shared current rating does not confirm compatibility with a 5V installation.
