Mean Well SPD-20HP-480S Surge Protection Device 347~480VAC 20KV
Overview
SPD-20HP thermally protected Surge Protective Device is a self-protected device which is specially designed to be used in outdoor and commercial LED lighting fixtures for transient overvoltage protection. It is constructed with thermally protected varistor technology. Its built-in thermal disconnect function provides additional protection to prevent catastrophic failure and fire hazard even under the extreme circumstances of varistor end-of-life or sustaining over voltage conditions. The SPD-20HP provides coordinated surge protection with more LED drivers than other SPDs due to its exceptionally low Measured Limiting Voltage (MLV) and Voltage Protection Level (UP). This lower clamping voltage can also help to extend the life-time of the luminaire. It also features a built-in LED indicator that notifies when replacement of the module is needed.

Test conditions and notes5
- 1. MCOV/UC: Maximum Continuous Operating Voltage - maximum r.m.s. voltage that could be continuously applied to the SPD.
- 2. MLV: UL1449 Measured limiting voltage; the highest value of residual voltage measurements during the application of impulses of 8/20μs nominal discharge current (In); an average voltage value of 15 impulses.
- 3. UP : IEC 61643-11 Voltage protection level; the highest value of residual voltage measurements during the application of impulses of 8/20μs nominal discharge current(In); a rounding voltage value of maximum measurement.
- 4. Nominal Discharge Current In (A): The nominal discharge current is a measure of the SPDs endurance capability; 15 impulses of discharge current uses the 8/20μs current waveform.
- 5. Maximum Discharge Current Imax (A): The maximum discharge current is a measure of the SPDs maximum capability; single impulse of discharge current uses the 8/20μs current waveform. All Devices pass maximum discharge current with possible, safe opening of thermal disconnect.

FAQ
What is the Mean Well SPD-20HP-480S used for?
The SPD-20HP-480S is a surge protection device designed for LED driver protection. It is intended for applications using Class I insulation and helps protect equipment from high-energy surge events.
What voltage range is this surge protection device designed for?
This model is designed for 347~480VAC applications, as indicated by the product name. That makes it suitable for higher-voltage lighting and power environments where protection at that range is required.
How much surge protection capability does the SPD-20HP-480S provide?
The SPD-20HP-480S provides up to 20kA maximum discharge current at an 8/20 microsecond waveform. It is also described as having 20KV surge protection capability for demanding protection scenarios.
Can this model be used outdoors or in harsh environments?
Yes. The SPD-20HP-480S has an IP66-rated design for indoor or outdoor installations, and its operating temperature range is -40°C to 75°C. Those specifications make it appropriate for challenging environmental conditions.
How can I tell if the SPD-20HP-480S needs servicing?
This model includes an LED status indicator. The indicator illuminates during normal status and turns off when servicing is needed.
What makes the SPD-20HP-480S a good fit for commercial LED protection projects?
This model combines a high 20kA maximum discharge current, 20KV surge protection capability, UL1449 Type 4 component assembly classification, and an IP66 enclosure design. That combination makes it a strong option for commercial LED driver protection where durability and clear status indication matter.
What is the warranty period for the SPD-20HP-480S?
The listed warranty period for this model is 1 year. For procurement or project planning, that gives buyers a defined coverage term for this specific surge protection device.
