10kV LED SPD for Outdoor Lighting Infrastructure Requiring DALI Surge Protection and RS485 Surge Protection
For lighting OEMs, electrical contractors, and EPCs deploying luminaires in outdoor road lighting, tunnel and underground traffic lighting, landscape lighting and outdoor signage, outdoor lighting for industrial plants, and public lighting for transportation hubs, coordinated surge protection across both AC power and data lines is non-negotiable. The 10kV LED SPD SPD-AC10KV-DS/II delivers integrated Type 2+3 combined AC and dataline surge protection — uniquely combining 10kV combination waveform immunity (Uoc 10kV, IEC 61643-11 Class III test) with native support for DALI2.0, D4i, 1–10V, DMX, and RS485 control signals. This makes it a purpose-built LED data line surge protection solution for Class II luminaires operating on 230V single-phase TN networks.
What Is the SPD-AC10KV-DS/II?
The SPD-AC10KV-DS/II is a LED SPD engineered as a Type 2+3 combined AC and dataline surge protection device. It is specified for Class II luminaires on 230V single-phase TN systems with input voltage 220–240V. Its AC-side maximum operating voltage is Uc 320Vac; its data-side maximum operating voltage is Uc 28Vdc. It uses MOV+GDT technology and provides Common/Differential Mode protection. Key ratings include:
- Nominal discharge current: In 5kA
- Maximum discharge current: Imax 10kA
- Combination waveform: Uoc 10kV (1.2/50µs–8/20µs)
- Protection level: UpL 50V at In (8/20µs); UpL/N 1.5kV at In (8/20µs)
- Max. load current: 5A at 25°C
- Admissible short-circuit current: Isccr 300A
- IP rating: IP20
- Operating temperature: –40°C to +85°C
- Housing material: Thermoplastic UL94 V-0; insulating material: PA66
- Weight: 48g; packaging dimensions: 60.5 × 40.5 × 28.6 mm
Where This LED SPD Is Used
This outdoor lighting SPD is validated for deployment in the following infrastructure applications:
- Outdoor road lighting
- Tunnel and underground traffic lighting
- Landscape lighting and outdoor signage
- Outdoor lighting for industrial plants
- Public lighting for transportation hubs
Selection and Installation Guidance
Selection must align strictly with system parameters: 230V single-phase TN network, Class II luminaires, and supported control protocols (DALI2.0, D4i, 1–10V, DMX, RS485). Installation requires series connection using a single screw contact with input/output on one side; wire cross-section must not exceed 1.5mm². Mounting is on-plate only. The unit operates within IP20 and is rated for ambient temperatures from –40°C to +85°C. In failsafe mode, the device disconnects the circuit, turns off the green LED, and cuts power — ensuring safe isolation after end-of-life or overload.
Compliance and Certification
The SPD-AC10KV-DS/II complies with:
- IEC 61643-11
- EN 61643-11
- IEC 61643-21
- EN 61643-21
Certified to CE, CB, and RoHS requirements.

Frequently Asked Questions
- Q: Is this LED SPD suitable for 230V outdoor luminaires with DALI or RS485 control lines?
A: Yes — it is designed for 230V single-phase TN systems and Class II luminaires, with dedicated Uc 320Vac (AC) and Uc 28Vdc (data) ratings, and full support for DALI2.0, D4i, 1–10V, DMX, and RS485. - Q: How is this LED SPD connected and mounted?
A: It uses series connection with a single screw contact for input/output on one side, accepting up to 1.5mm² wire, and mounts directly on plate. - Q: What happens when the SPD enters its failsafe state?
A: It safely disconnects the circuit, deactivates the green LED, and cuts power to prevent downstream risk.
