Product Usage Instructions:

Installation

Ensure the input power matches the specifications of the power supply.
Connect the output wires to the appropriate devices, observing polarity.
Secure the power supply in a well-ventilated area to allow for proper cooling.

Operation

Turn on the power supply using the remote ON-OFF control or switch.
Monitor the LED indicator to ensure power is on.
Avoid overloading the power supply beyond its rated capacity.
If any protection feature is triggered, investigate and resolve the issue before reuse.

Maintenance

Regularly check for dust or debris accumulation that may hinder cooling.
Inspect the power supply for any physical damage or loose connections.
Keep the power supply away from moisture or direct sunlight.

FAQ

Q: What should I do if the LED indicator does not light up?
A: Check the input power connection and ensure it is within thespecified range. If the issue persists, contact customer support.
Q: Can I use the power supply with devices that have different voltage requirements?
A: No, it is recommended to match the voltage output of the power supply with the requirements of the connected devices to avoid damage.
Q: How can I test if the power supply is functioning correctly?

NOTE|

All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
Tolerance : includes set up tolerance, line regulation and load regulation.
33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
