In summary, the LDS70 series of LED drivers enable compact LED lighting solutions, up to 70 W, that require a system life greater than fifty thousand hours. This series has current ratings up to 5 A, voltage ratings up to 58 V, and an operating temperature of -40ºC to +80º C. There are two input voltage ranges in the series: the U models have a wide 100 to 240 VAC input voltage range; and the H models have a wide 120 to 277 VAC input voltage range. The LDS70 has an efficiency rating of 88% at 230 VAC or 87% at 115 VAC. All models come pre-certified with critical safety specifications and regulatory requirements. The LDS series has numerous important features and benefits. The supplies can support system life requirements greater than seventy thousand hours, with no forced air necessary for cooling and both models have no minimum load requirement. Active power factor correction rated at 0.9 typical minimizes input harmonic current distortion. In addition, current levels can be preset by the system designer or adjusted in the application to perform dimming functions.
