The Harvia LED-PWS-24-90 is an electrical power supply designed for compatible 24 V DC lighting systems. Correct installation is essential to ensure safe and reliable operation. Because the unit is connected to a 230 V mains electrical supply, installation and electrical connection work must be performed by a suitably qualified electrician in accordance with the manufacturer's instructions and applicable electrical regulations.
Electrical supply and output voltage: The specified primary energy source is electricity at 230 V, 1N~, with a frequency of 50/60 Hz. The output voltage is 24 V DC, and the maximum specified power is 90 W. Before connecting any equipment, the installer must confirm that the connected lighting components or controllers are designed for the supplied output voltage and that their combined power consumption does not exceed the permitted capacity.
The distinction between the mains input and the low-voltage DC output is particularly important. Equipment intended for a different voltage must not be connected directly to the 24 V DC output. Incorrect voltage selection can damage connected components or create electrical hazards.
Dry installation location: The power supply must be installed in a dry location. It is not protected against splashing water and must therefore not be positioned where it may be exposed to water droplets, direct splashing, condensation or unsuitable levels of moisture. This requirement is especially important when planning electrical installations for sauna rooms and surrounding wellness areas.
The power supply should not be installed directly in a wet area or in a location exposed to excessive heat unless the manufacturer explicitly permits that installation arrangement. The actual installation location must comply with the applicable environmental limits and all requirements stated in the product documentation.
Mounting and positioning: Before installation, sufficient space must be available for the unit and its electrical connections. The device measures approximately 145 mm in depth, 59 mm in width and 32 mm in height. These dimensions assist with installation planning but do not replace any required mounting clearances stated by the manufacturer.
The unit should be mounted securely in accordance with the manufacturer's instructions. Cable connections must not be subjected to excessive mechanical stress, and the installation should allow appropriate access for inspection or servicing where required.
Power calculation: The maximum output rating of 90 W must be considered when designing the lighting system. The total connected load should be calculated using the specified power consumption of the lighting fixtures and any additional components powered by the unit. The system must not be operated beyond the manufacturer's permitted output rating.
For Harvia RGBW LED tubes, the manufacturer identifies the 90 W power supply as suitable for installations with a total tube length of up to 5 metres. This recommendation applies to the corresponding compatible lighting equipment. Other LED products may have different power requirements and must be evaluated individually.
DMX lighting integration: When used with DMX-controlled lighting, the power supply must be connected according to the specifications of the relevant controller and driver. A DMX controller controls lighting functions, while the power supply provides electrical energy. These functions should not be confused during installation.
The installer must verify that the selected DMX controller and lighting driver are electrically compatible with the 24 V DC supply. The necessary connection arrangement depends on the equipment used and must follow the appropriate manufacturer documentation.
Electrical connections: All connection and installation work must be carried out with the electrical supply disconnected. Correct polarity, secure terminals and appropriate cable specifications are essential. The supplied connection cable must be used only for its intended purpose and in accordance with the manufacturer's instructions.
Additional cables and connectors must be selected to suit the expected electrical load and the installation environment. Connections must be protected from accidental damage, excessive mechanical tension and unsuitable environmental conditions.
Initial commissioning: Before the power supply is switched on for the first time, the complete installation should be checked. The installer should verify the mains connection, output wiring, polarity, connected load and compatibility of all lighting and control components.
After commissioning, the lighting system should be tested to confirm that the connected equipment operates as intended. Where DMX control is used, the controller and driver should be checked separately to ensure that the required lighting functions respond correctly.
Operation and maintenance: The power supply should be used only for its intended electrical application. It must not be exposed to water or operated in conditions that do not comply with the manufacturer's requirements.
If unusual operating behaviour, visible damage, overheating or other signs of a malfunction occur, the system should be disconnected from the electrical supply and inspected by a qualified specialist. The power supply must not be opened or modified by unauthorised persons.
The manufacturer's current installation and operating documentation must always be consulted before installation. Technical values, environmental limitations and connection requirements stated in that documentation take precedence over general installation recommendations.
A correctly installed Harvia LED-PWS-24-90 contributes to a well-coordinated sauna lighting system by providing the required 24 V DC supply within its specified power limits. Careful planning of the installation environment and connected equipment is essential for reliable long-term operation.
