EVL80WLED-STCH03

EVL80WLED-STCH03 80W-1A primary side current loop control LED driver with STCH03 for street lighting applications Data brief Due to current primary side STCH03 control loop, the output stage is composed of a simple diode rectification and the output capacitor. Form factor is compatible with street lighting application. At full load the efficiency is above the 90% at nominal voltages and remains very close to this value till half the load. Output short-circuit and no-load protections are auto-restart for a safe operation in lighting environment. Features  Input voltage: Vin: 90 - 265 Vrms, f: 45-66 Hz  LED string range: [40 -80] V / 1A Low input power is there at no-load conditions.  Output current ripple < 50 mA  Fast startup: сϴϬs s>сϳϬs s>сϲϬs s>сϱϬs s>сϰϬs ϴϲ͘ϬϬй ϴϰ͘ϬϬй ϴϮ͘ϬϬй ϴϬ͘ϬϬй ϵϬ ϭϭϱ ϭϰϬ ϭϲϱ ϭϵϬ Ϯϭϱ ϮϰϬ Ϯϲϱ sŝŶ΀sĂĐ΁ Figure 3.

At the end of its life cycle, differentiated waste collection must be followed. Consult local authorities for more information on the proper disposal channels. It is mandatory to separately collect the evaluation board and make sure it is delivered to the appropriate waste management and recycling centers. As of 15 August 2018, in all countries belonging to the European Union, the evaluation board is subject to the WEEE Directive 2012/19/EU requirements and therefore it is forbidden to dispose of the evaluation board as undifferentiated waste or with other domestic waste. Consult local authorities for more information on the proper recycling centers. Disposing of the evaluation board incorrectly may cause damage to the environment and may be subject to fines based on the rules of specific countries.
