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.
Please contact MEANWELL for 320~370VDC application.
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 altitude higher than 2000m(6500ft).

Function Manual

Remote Sense
The Remote Sense compensates voltage drop on the load wiring up to 0.5V
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 to 40~115% of the nominal voltage by applying EXTERNAL VOLTAGE.
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.
Current Sharing with Remote Sense
RSP-2000 has the built-in active current sharing function and can be connected in parallel, up to 4 units, to provide higher output power as exhibited below :
- The power supplies should be paralleled using short and large diameter wiring and then connected to the load.
- Difference of output voltages among parallel units should be less than 0.2V.
- The total output current must not exceed the value determined by the following equation:
  Maximum output current at parallel operation=(Rated current per unit) (Number of unit)××0.9
- Under parallel operation, the minimum output load should be greater than 5% of total output load; otherwise, it is likely that only one unit operates whereas other units may enter standby mode or their LED status indicators may not turn on.
- When the total output current is less than 5% of the total rated current, or say (5% of Rated current per unit)×(Number of unit) the current shared among units may not be fully balanced.
