Frequently asked questions
What is the MQ300PC4.5 output voltage and current?
The listed output is 4.5V DC at 60A.
Does the MQ300PC4.5 work with 110V AC input?
110V AC is within the listed 100–240VAC input range. The stated input frequency is 50/60Hz.
What is the maximum input current?
The maximum input current is listed as 5.0A. This is not the DC output current rating.
Which protections are included?
The listed functions are input undervoltage, overload and short-circuit protection. Cooling is by ventilation.
Can the 4.5V model be used in place of a 5V supply?
Check the LED module’s voltage requirement first. Similar model names and current ratings do not establish compatibility between 4.5V and 5V supplies.
