Mean Well SPD-10S-277S Surge Protection Device 120~277VAC 10KV
Overview
SPD-10S-277S 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. It also features a built-in LED indicator that notifies when replacement of the module is needed.

Test conditions and notes6
- 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.
- 6. Tested with G/PE connection (Class I application). SPD Protection against L-G/PE, N-G/PE voltage surges cannot be achieved without connecting it to G/PE.

FAQ
What is the Mean Well SPD-10S-277S used for?
The Mean Well SPD-10S-277S is a surge protection device designed for 120~277VAC applications. It is intended to help protect equipment from surge events with up to 10kV surge protection capability. This model is commonly considered for LED driver and power supply applications where AC-side surge protection is needed.
What surge protection performance does the SPD-10S-277S provide?
This model is rated for 10kA maximum discharge current (Imax) with an 8/20 microsecond waveform. It also features 10kV surge protection capability. The product is described as providing line-to-ground and line-to-line protection.
What input voltage range is this surge protection device designed for?
The SPD-10S-277S is designed for 120~277VAC systems. Its MCOV is listed as 320VAC. Buyers should match it to equipment and applications that operate within this AC voltage range.
Can the SPD-10S-277S be used indoors and outdoors?
Yes, this model has an IP66 design for indoor or outdoor installations. That makes it suitable for environments where dust resistance and protection against strong water exposure are important. It is also built with thermal protection for added durability.
How can I tell if the SPD-10S-277S needs service?
The unit includes an LED status indicator. The indicator is illuminated during normal status and turns off when the SPD has reached end-of-life and needs replacement. This provides a quick visual check of the device condition.
What operating temperature range does the SPD-10S-277S support?
This model is specified for operation from -40°C to +85°C. That wide temperature range supports use in demanding indoor and outdoor environments. Buyers evaluating harsh conditions should confirm the rest of the system is rated similarly.
