Product Description
Specifications

SML economic Led power supply Features:
1) Specialized manufacturer
2) Built-in EMI filter
3) 100% full load burn-in test

SML economic Led lighting designed series power supply working condition:
1. Switch: Electric power and electronic component working at on/off state not linear state
2. High frequency: Electric power and electronic component working at high frequency not the low frequency near to power frequency
3. DC: Power supply output DC not AC voltage
SML economic Led lighting designed series power supply working characteristic:
1. Small volume, low weight: It's only 20~30% of linear power supply becuase without the power frequency transformer
2. Small wattgae, high efficiency: Power transistor working at on/off state, so the power waste of transistor is small, conversion efficiency is high, usually 60~70%, but the linear power supply is only 30~40%
