Start with the strip’s rated voltage, then calculate the total connected wattage. A 24V constant voltage strip needs a compatible 24V supply with enough usable capacity for the load and the installation conditions. Next, check dimming, environmental protection and physical fit. ELG, HLG, XLG, LPV and SPWM offer different routes through these requirements; the model number and suffix determine the final specification.

A constant voltage supply maintains a specified voltage, such as 12V or 24V, while the connected equipment draws the current it needs within the supply’s limits. A constant current driver regulates current for a compatible LED load within a stated voltage range. Most of the strip-light power supplies featured here are selected for constant voltage applications. Match the driver type to the LED manufacturer’s specification rather than treating the two types as interchangeable.

Use the voltage specified for your LED strip or lighting equipment. For the same wattage, a higher-voltage system draws less current, which can help with cable losses when the complete system is designed accordingly. This does not make a 48V supply compatible with a 24V strip. The cable length, cable size, maximum strip run and feed arrangement still need to be checked. The 5V options in this collection serve suitable 5V loads.

Use the LED manufacturer’s loading guidance and the selected driver’s derating information. The estimator on this page uses 80% loading as a planning example: a 96W load gives a 120W capacity target. That allowance is not a universal approval for an installation. High temperatures, low input voltage, mounting conditions or control equipment may require a different allowance. Choose a suitable available rating above the calculated target and verify the full specification.

No. Dimming depends on the series and the complete model suffix. Some drivers offer an adjustment of the output, which is different from accepting a remote dimming signal. SPWM models in this collection include DALI-2 DT6, DALI-2 DT8 and three-in-one options. Other installations may use a suitable constant voltage supply with a separate compatible LED controller. Do not connect a mains dimmer unless the exact driver is designed for that method.

DT6 describes control gear used for LED control, including single-channel dimming applications. DT8 adds colour-control capabilities such as tunable white or RGBW on supporting equipment. The SPWM DA2 and DA2Q products shown here distinguish these use cases. Match the driver, control system, strip type and channel wiring, and check the supported operating mode before selecting your components.

An appropriately specified IP67 driver can be considered for suitable outdoor installations, but the rating applies to the unit under its stated test conditions. Cable joints, connectors and the rest of the installation need their own environmental protection. Check the model’s installation instructions, mounting position, temperature limits and exposure conditions. An IP67 label does not by itself make a driver suitable for permanent submersion.

The ending of a MEAN WELL model number can identify different adjustment, dimming or other design options. Two products with the same headline series, voltage and wattage may therefore behave differently. Read the full product code and datasheet when replacing a driver; do not assume that an A, DA, DA2 or DA2Q version is a direct substitute for another variant.

It may be possible when the strips use the same compatible supply voltage and the combined maximum load stays within the usable capacity. Each branch also needs an appropriate cable, connection and protection arrangement. Check the controller’s total and per-channel ratings if one is fitted. Dividing a large installation into planned zones can simplify cable routing, maintenance and future changes.

An inrush limiter is an AC-side accessory used to control the brief surge of current when suitable power supplies switch on. It is not an LED driver and does not provide a regulated 12V or 24V output. The ICL-16L and DIN rail ICL-16R are included separately in the catalogue’s accessory filter. Selection needs to consider the connected supplies, continuous current and circuit protection.

Record the entire model number and compare input, output voltage, output current or power, dimming method, enclosure rating and physical dimensions. Check terminal arrangements, cable lengths and mounting points as well. If the original unit is discontinued or its suffix is different, share the label details and application with LED Technologies so the replacement can be assessed against the complete installation.

No. Warranty, efficiency, protection features and temperature limits vary by model. The supplied collection includes warranty periods from two to seven years. Efficiency figures are stated at specified operating conditions, while available output can change with temperature or input voltage. Use the figures and conditions for the exact product; a range’s headline maximum does not apply to every driver.
