Scope of application

• Supply of single-color LED strips and LED tapes, e.g. for decorative and advertising lighting
• Office, commercial and residential lighting
• Hotels, classrooms, warehouses, healthcare, retail, as well as display and shop window lighting
• Retrofitting existing luminaires (retrofit) and planning new lighting concepts
• For dry indoor areas only (IP20 protection rating)

Scope of delivery

• 1 × dimmable 150W constant voltage LED driver in the selected version (12V DC or 24V DC)
• Fully insulated protective housing with integrated mounting tab
• Operating and installation instructions (User Manual)

Installation Instructions

• Input voltage 220–240 V AC, 50/60 Hz; output depending on version 12V DC or 24V DC (observe polarity +/- on the LED strip)
• Compatible with leading-edge triac and trailing-edge ELV dimmers (dimmer voltage range 40–220 V AC); for dimming down to 1%, the dimmer must support a 1% minimum dimming level
• Alternatively, control via AC push-dim using standard push buttons (NO/momentary switch): short press = on/off, long press (1–6 s) = stepless dimming, each subsequent long press reverses the direction
• Dimm level memory: The light returns to the last set brightness after switching off and on again – even after a power failure
• Synchronization of multiple drivers to one push button is possible (long press > 10 s); max. 25 drivers per push button recommended, max. cable length from push button to driver 20 m
• Note: Triac and push-dimming cannot be used simultaneously; after push-dim operation, change the triac signal by more than 10% to reactivate the triac control
• Installation and configuration only by qualified specialist personnel; the device is not waterproof – install in a waterproof enclosure in damp environments
• Maintain sufficient distance from heat sources (approx. 20 cm between devices recommended) and ensure good heat dissipation; operating temperature -20 °C to +45 °C
• Before switching on, check all wiring for correct connection (risk of short circuit)

What is an LED power supply?

An LED power supply (also known as an LED transformer or LED power source) converts the standard mains voltage of 230V into the direct current (usually 12V or 24V) required for LED strips. It is an essential component of any LED installation and must be selected to match the power and voltage of the LEDs.

What voltages are common for LED power supplies?

Common output voltages are:

5V: typical for addressable LED strips such as WS2812 or SK6812

12V: common for shorter distances and standard LED strips

24V: ideal for longer LED strips or applications with lower voltage drop

48V: designed for particularly long distances

How do I calculate the right power for my power supply?

The required power is determined by the total power of all connected LED strips in watts. You should also include a safety margin of approx. 10%.

Example:
An LED strip with 10 W/m, length 5m → 50W + 10% margin = at least 55W power supply capacity.

What types of LED power supplies are there?

  • Open power supplies (industrial form): for installation in enclosures with ventilation slots
  • Enclosed power supplies: protected, usually IP20 or higher.
    Variants with IP65 or IP67 even offer the option of installation in damp and outdoor areas
  • Plug-in power supplies: ideal for smaller LED projects, plug-and-play
  • DIN rail power supplies: for distribution in control cabinets

What does the IP protection rating mean for power supplies?

The IP protection rating indicates how well a power supply is protected against dust and moisture:

  • IP20: for dry indoor areas only
  • IP65 / IP67: for damp areas, outdoor use, or dusty environments

Can multiple LED strips be connected to one power supply?

Yes, as long as the total power of all strips does not overload the power supply and they are voltage-compatible.

Pay attention to:

  • sufficient cable cross-section
  • secure connections
  • additional feed points for longer distances

What happens if the power supply is too weak?

A power supply that is too weak can lead to flickering, color distortion, or even damage. The LEDs will no longer receive sufficient power – reliable operation cannot be guaranteed.

Can I use a power supply with too much power?

Yes, that is easily possible. LED strips only draw as much power as they need.

  • Advantage: more headroom, longer power supply lifespan
  • Disadvantage: excessive oversizing reduces efficiency and unnecessarily increases standby power consumption

How is an LED power supply connected?

  • Primary side (230V AC): L (Phase), N (Neutral conductor), PE (Protective earth, if present)
  • Secondary side (e.g. 12V DC): V+ and V–

⚠️ Important note: Connection to the 230V mains voltage must be carried out exclusively by a qualified electrician. Improper connection can lead to electric shocks, short circuits or fires.

Can I connect a power supply myself?

  • 230V connection: must only be carried out by a qualified electrician.
  • 12/24V side (low voltage): can generally also be connected by laypeople.
    ⚠️ Important note: Many power supplies have common terminal blocks where both the 230V input and the 12/24V outputs are located next to each other. For this reason, the wiring of such power supplies should always be carried out by a qualified electrician.

What is the difference between 12V and 24V power supplies?

  • 12V: Standard for many LED strips, suitable for shorter distances
  • 24V: Lower voltage drop, therefore better for longer distances
