Block Diagram

The block diagram illustrates the internal components and signal flow of the NDR-240 series power supply. It includes:

Input stage: EMI Filter, Rectifiers, PFC Circuit
Power Switching stage: PWM & PFC Control
Output stage: Rectifiers & Filter, O.C.P. (Over Current Protection), O.V.P. (Over Voltage Protection), O.T.P. (Over Temperature Protection)
Detection Circuit

The diagram shows the path from AC input (I/P, FG) through various stages to the DC output (+V, -V).

Derating Curve

The derating curve shows the relationship between ambient temperature and the load percentage. The power supply can operate at 100% load up to 50°C, after which the load capacity decreases linearly to 0% at 70°C.

Output Derating VS Input Voltage

The output derating versus input voltage graph indicates that the power supply maintains 100% output load across the entire input voltage range of 90VAC to 264VAC at 60Hz.

Mechanical Specification

The NDR-240 series has the following dimensions:

Width: 63mm
Height: 125.2mm
Depth: 113.5mm

The unit is designed for DIN rail TS35/7.5 or TS35/15 mounting.

Terminal Pin Assignment (TB1)

Pin 1: FG (Frame Ground)
Pin 2: AC/N or DC -
Pin 3: AC/L or DC +

Terminal Pin Assignment (TB2)

Pin 1, 2: DC OUTPUT -V
Pin 3, 4: DC OUTPUT +V

Installation Instruction

This series fits DIN rail TS35/7.5 or TS35/15. For installation details, please refer to the instruction manual available at: http://www.meanwell.com/manual.html

Note on Installation Clearances:

40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power.
In case the adjacent device is a heat source, 15mm clearance is recommended.

Notes

All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.
Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1 µF & 47 µF parallel capacitor.
Tolerance: includes set up tolerance, line regulation and load regulation.
Derating may be needed under low input voltage. Please check the derating curve for more details.
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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
The ambient temperature derating of 3.5°C/1000m with fanless models and of 5°C/1000m with fan models for operating altitude higher than 2000m(6500ft).
Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.
