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 0.1uf & 47uf parallel capacitor.
Tolerance : includes set up tolerance, line regulation and load regulation.
Derating may be needed under low input voltages. Please check the derating curve for more details.
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 720mm*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 altitudes higher than 2000m(6500ft).

Function Manual

Voltage Drop Compensation
- Remote Sense
  The Remote Sense compensates voltage drop on the load wiring up to 0.5V
- The +S signal should be connected to the positive terminal of the load whereas -S signal to the negative terminal.
- Local Sense
- The +S,-S have to be connected to the +V(signal), -V(signal), respectively, as the following diagram, in order to get the correct output voltage if Remote Sense is not used.
Output Voltage Programming (or, PV / remote voltage programming / remote adjust / margin programming / dynamic voltage trim)
- In addition to the adjustment via the built-in potentiometer, the output voltage can be trimmed by applying EXTERNAL VOLTAGE.
- The rated current should change with the Output Voltage Programming accordingly.
- For Remote Sense / Local Sense, please refer to “Voltage Drop Compensation” section.
Remote ON-OFF Control
The power supply can be turned ON/OFF individually or along with other units by using the “Remote ON-OFF” function.
