Ampere (CC)	0,70 A

The Synergy 21 LED power supply with manufacturer number S21-LED-D00033 is a constant current power supply (CC) for LED panel systems of the PRO V3 and V4 PRO component groups. It serves as a power source for LED surface luminaires with dimensions of 620×620 mm, particularly for the models LED backlite panel 620×620 WW/NW V4 PRO and LED Panel 620×620 PRO V3. The device is designed to be flicker-free, ensuring uniform light output without visible flickering phenomena, making it suitable for use in offices, workspaces, or other applications requiring high lighting quality.

Applications
This power supply is designed for indoor use where stable and reliable power supply for LED panel luminaires is required. It is particularly suitable for applications in offices, administrative buildings, schools, or retail environments, where lighting quality and operational safety are prioritized. The operating temperature range of -20 to +50 °C allows use in rooms with varying ambient temperatures without affecting functionality.

Functions and Features in Detail
The power supply delivers a constant current of 0.70 A at an output voltage of 30 to 42 volts. The maximum power is 29.4 watts, sufficient to power the intended LED panel models. Power supply is from the mains (220–240 VAC), and the device is not dimmable. The housing dimensions are 114.5 × 40.5 × 28 mm, and the housing is made of plastic in white. The compact design enables easy mounting and placement within the installation system.

Technology Explained Simply
As a constant current power supply (CC), the device ensures a constant current regardless of load, which is necessary for the correct operation of LED modules. The output voltage of 30–42 V is adapted to the electrical requirements of the LED panel modules. Flicker-free operation ensures light is produced without visible flickering, reducing eye strain and improving light quality. The operating temperature range of -20 to +50 °C demonstrates the device’s robustness against environmental influences.

Compatibility and Accessories
The power supply is specifically developed for the LED panel models 620×620 PRO V3 and V4 PRO. It is not suitable for other LED systems with different current or voltage requirements. Various mounting kit accessories are available in the range, such as suspension sets, clips, or power supply connectors, which assist in installing LED panel luminaires. Additionally, other power supply variants are available, for example, dimmable models with 0–10 V or DALI control, which are not compatible with this item.

Mounting and Installation
Installation must be carried out by qualified personnel. Before mounting, the power supply must be switched off to avoid electrical hazards. The power supply is connected to the mains (220–240 VAC) and linked to the LED panel. Mounting typically occurs within the installation system or in the ceiling space, ensuring sufficient ventilation to prevent overheating. The use of appropriate connection cables and mounting accessories is recommended to ensure a safe and stable installation.

Operational Advantages
The power supply provides reliable power for LED panel luminaires with high efficiency. Flicker-free operation ensures pleasant light quality, reducing eye strain. The operating temperature range of -20 to +50 °C enables flexible use in various environments. The compact design and robust plastic housing in white integrate well into existing installation systems. The 60-month warranty highlights the product’s reliability.
