2 / 8 page LB115S 115W Single Output LED Series www.slpower.com LB115S 2-OCT-14 2 Efficiency Typical Measured @ 25˚C LB115S12K 89% @230V ac, full load 86.5%@115V ac, full load LB115S24K 89% @230V ac, full load 87%@115V ac, full load LB115S48K 90% @230V ac, full load 88%@115V ac, full load LB115S56K 90% @230V ac, full load 88%@115V ac, full load Operating Temperature -20˚C to 70˚C -40˚C start up (full load) For 12V output, the maximum load is 75% Storage Temperature -40˚C to 85˚C Turn-on Time: <2 Seconds @115Vac(<3S for 12V output) <5 Seconds @115Vac for -20˚C ambient Hold-up Time: 12mS minimum from loss of ac input at 115 Vac DC Output Specifications PARAMETER SPECIFICATION NOTES Output Power: Max of 75 Watts for Convection cooled Maximum 108 Watts for 12V output -20 to 50˚C ambient Max of 115 Watts for fan cooled (48 & 56V Models) Cooling: Convection Forced Air of 200 LFM Total Regulation: ±2% for all models Total regulation is the maximum deviation from nominal voltage for all loading conditions Overload Protection: 120% - 180% of rated output current value, Hiccup Mode For 12V output, it is 110 to 180% Short Circuit Protection: Short across the output terminals will not cause damage to the unit. Hiccup Mode Overvoltage Protection: OVP firing reduces output voltage to <50% of nominal in <50mS. See chart for trip range Overtemperature Protection: Automatic Power Shutdown Thermistor temperature is 130˚C Minimum Load: No minimum load is required Ripple and Noise: 0.5% RMS, 1% pk-pk for all models. 20 MHz Bandwidth, differential mode. Measured with noise probe directly across output terminals, and load terminated with 0.1µF ceramic and 10µF low ESR capacitors Transient Response: 500µs typ. response time for return to within 0.5% of final value for a 50% load change, ∆i/∆t< 0.2A/µs. Max. voltage deviation is 3.5%. Measured @ 25˚C Overshoot: 5% overshoot at turn-on, 5% overshoot at turn-off, under all conditions. 6% for 12V output |
