LTSYS SE-8 Series Intelligent LED Driver User Manual

Utilize leading edge (Triac) or trailing edge (ELV) phase
control dimming for adjusting the brightness levels. The dimming
depth can be adjusted from 0.1% to 100%.

Protection Features:

The driver includes overheat, overvoltage, overload, and short
circuit protection. It will automatically recover once the issue is
resolved.

Maintenance:

The driver has a normal service life of up to 100,000 hours.
Regularly check for any signs of damage or malfunction.

FAQ

Q: What should I do if the driver exceeds the rated power?

A: The device will automatically protect itself when the load
exceeds 102% of the rated power. Reduce the load to allow for
automatic recovery.

Q: Can the driver be used with all types of light
fixtures?

A: The driver is suitable for Class I, II, and III indoor light
fixtures.

Remarks 1. Test ConditionsCold start 10A(Test twidth=300us tested under 50% Ipeak)/230Vac 2.The number of supported drivers may vary depending on the brand and model of the MCB. 3.It is recommended not to exceed the specified load capacity during on-site installation. The actual load should be determined based on field conditions. 4.If the ambient temperature exceeds 30°C or multiple MCBs are installed side by side, the number of installed drivers must be reduced and recalculated accordingly. 5.Electricians typically use Type B MCBs for residential lighting and Type C MCBs for commercial lighting applications. 6.Different testing equipment may yield variations in measured current peaks and pulse widths. Always use professional-grade instruments for accurate testing.

Installation Precautions

15cm 15cm

15cm

Please do not stack the products. The distance between two products should be 15cm so as not to a ect heat dissipation and the lifespan of the products.
Note: The installation should be in line with the environmental operating temperature of the product. Do not install it inside the lamp to avoid exceeding the environmental operating temperature of the product, which may affect the product’s lifespan.

Please not place the products on LED drivers. The distance between the product and the driver should be 15cm so as not to a ect heat dissipation and shorten the lifespan of the products.

Woodiness

Gasket

Do not x the product screws tightly against the wooden board. Instead, add a washer with a thickness of 7mm under the xing screws. Leaving some gaps can e ectively dissipate heat, preventing any impact on the product’s heat dissipation performance and service life.
