Lighting accessory Synergy21 S21-LED-SR000075, grey, 50 W, 100–240 V AC, IP20, 210×50×? mm

Synergy21 S21-LED-SR000075 is a grey lighting accessory that combines a single‑channel LED controller with an integrated constant‑current power supply. The unit provides up to 50 W output and accepts 100–240 V AC at 50–60 Hz for indoor installations. With adjustable output current between 200 and 1500 mA, the device is designed to drive single‑color LED strips and modules, offering current regulation to maintain consistent brightness and support dimming in suitable setups. The compact enclosure (approximately 210 × 50 mm) and lightweight design make it suitable for constrained installation spaces where a combined driver/controller is preferred.

Advantages

The integrated constant‑current design delivers stable LED drive across the adjustable current range, reducing flicker and protecting LEDs from current variations. Combining controller and power supply into one compact unit simplifies wiring and installation and reduces the need for multiple separate components. The wide, adjustable output current range increases compatibility with various single‑color LED types and forward voltage conditions, while conformity to RoHS and CE standards and an IP20 rating makes the unit appropriate for indoor, fixed installations.

Suitable for

• Indoor single‑color linear LED strips in coves, undercabinet and display lighting
• LED modules and arrays requiring constant‑current drive and dimming
• Backlighting and signage where consistent brightness and reliability are needed
• Architectural accent lighting and retrofit projects with limited space

Key specifications

• Output mode: single‑channel constant‑current LED driver
• Output current range: 200–1500 mA (adjustable)
• Maximum output power: 50 W
• AC input: 100–240 V AC, 50–60 Hz
• Protection rating: IP20 (indoor use)
• Operating temperature range: −20 °C to 50 °C
• Typical dimensions: 210 × 50 mm; weight approximately 200 g

How to use

Install the unit in a dry, ventilated indoor location close to the LED load to minimize wiring losses. Connect the AC mains input in accordance with local electrical codes, observing proper grounding where required. Wire the LED output to the single‑color strip or module with correct polarity. Set the output current within the 200–1500 mA range to match the LED forward current rating and desired luminous output, ensuring the total connected LED power does not exceed 50 W. If dimming capability or an external control interface is available, follow the manufacturer’s instructions for integrating those controls.

Usage recommendations

Select an output current that corresponds to the LED manufacturer’s recommended forward current rather than continuously operating at the maximum power limit. Provide adequate ventilation around the unit, keep AC and DC cable runs as short as practical, and use conductors sized for the expected current to reduce voltage drop and heat buildup. Observe local wiring regulations and safety standards during installation and maintenance.
