Overview

NHDD-40-100 is the model of this series: rated power 35W (typical), typical efficiency 94%. Type Blank: Pin style.

NHDD-40 series is a DC/DC LED driver. It operates from 360 ~ 420VDC and offers constant current output. Thanks to the efficiency up to 94%, with the fanless design, the NHDD-40 is able to operate for -30℃~+90℃ case temperature under free air convection. In addition,NHDD is a paritcular design for DC 380V Bus lighting application which can be combination with storang. This coincides with the developing trend that countries around the world have begun to implement of energy saving and carbon neutrality, how to combine renewable energy sources, and effectively integrate DC power grid and energy storage systems. MEAN WELL will continue to provide products corresponding with this goal in order to reduce the loss in the power conversion and create new DC power grid lighting applications.

Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 380VDC input, rated current and 25℃ of ambient temperature.
2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
3. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
4. Efficiency is measured at 100mA/380VDC.
5. The power supply is regarded as a part of the components in the system, and the final EMI test needs to be tested with the final device. If an additional EMI filter circuit is required to meet the electromagnetic compatibility requirements, please refer to the EMC test report for details. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
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).
7. Please evaluate this notice carefully to prevent high unexpected output current. Output voltage and total forward voltage of LED must step down at least 40VDC from input voltage. Maximum step down voltage should not exceed 80VDC.

FAQ

What is the Mean Well NHDD-40-100 designed for?

The NHDD-40-100 is a constant current LED driver intended for DC bus lighting applications. It is part of Mean Well's NHDD-40 series and is positioned for 380V DC lighting systems, including projects that may be paired with green energy storage or intelligent lighting systems.

What are the key electrical ratings of the NHDD-40-100?

This model is rated at 35W (typical) with a constant current output of 100mA. The listed output voltage is 350V (typical), and the product description states it operates from 360-420V DC.

Does the NHDD-40-100 support dimming or remote control?

Yes. This model includes PWM dimming capability and supports remote ON/OFF control. That makes it suitable for applications where brightness control or centralized switching is required.

What environments is the NHDD-40-100 suitable for?

The driver is built with a fanless, fully encapsulated plastic housing for reliable operation in demanding conditions. The provided product data lists an operating case temperature range from -30°C to +40°C, and the series description highlights free-air convection cooling.
