Product Usage Instructions

Installation

Choose a suitable location for installing the power supply.
Ensure that the DIN rail TS-35/7.5 or 15 is securely mounted.
Slide the power supply onto the DIN rail until it clicks into place.
Verify that the power supply is firmly attached to the DIN rail.

Electrical Connections

Before connecting any wires, ensure that the power supply is turned off.
Connect the input wires to the appropriate AC power source terminals.
Connect the output wires to the load terminals.
Double-check all connections to ensure they are secure.

Operation

Turn on the AC power source.
The T4 LED indicator will light up, indicating that the power supply is receiving power.
Verify that the DC OK relay contact is closed, indicating that the output voltage is within the specified range.
If the LED indicator or relay contact does not function as expected, refer to the troubleshooting section of the user manual.

NOTE| 1. All parameters NOT specially mentioned are measured at 230VAC 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. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on http://www.meanwell.com)

5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.

6. 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).
