120W 24V DIN Rail Power Supply — Mean Well NDR-120-24 Compatible
Narrow-profile DIN rail LED power supply engineered for electrical panel installations where every millimeter of rail space matters. At just 40mm wide, the BrightLink NDR-compatible unit delivers 120W of clean 24V DC output in a metal-cased design that dissipates heat through the DIN rail itself — eliminating the need for panel ventilation modifications. Direct drop-in replacement for the Mean Well NDR-120-24 with identical footprint and terminal placement.
Key Features
- 40mm narrow width — Occupies minimal DIN rail space (EN 60715 standard), allowing dense packing of multiple supplies in a single panel
- 120W / 5A continuous — 24V output powers LED control panels, relay modules, and sensor networks within automation cabinets
- 93% efficiency — Low thermal dissipation enables operation up to 70°C ambient with natural convection — no panel fan required
- Metal housing — Aluminum case doubles as a heat sink and provides EMI shielding for sensitive LED control electronics
- Class B EMC — Meets EN 55032 Class B emission limits for installation in noise-sensitive environments like hospitals and recording studios
- DC OK relay contact — Built-in relay output signals power-good status to BMS or PLC systems for monitoring and fault logging

- Data center cabinet LED strip and indicator power
Installation Notes
Clip onto standard 35mm DIN rail using the integrated spring latch. For parallel output connection of multiple units, use the optional parallel kit to enable current sharing. The DC OK relay contact is accessible on the front terminal block — wire to a DI input on your PLC for power monitoring. Allow 25mm clearance above and below for convection airflow.
