25-W supplies target LED Lighting

The LDS25 series power supplies provide 25-W output that target LED lighting. They have an input range from 120 to 277 Vac and deliver up to 700 mA at 36 Vdc. Constant current mode operates from 36 V down to 26 V, while constant voltage mode operates with load currents from 300 to 700 mA. The output current can be user adjusted from 0 to 700-mA range by an IEC 60929 compliant dimming function.

The power supplies achieve a power factor of at least 0.9 and they feature 86% conversion efficiency. They are rated for operation over an ambient temperature range from −30 to 60C or a case temperature from −30 to 90C, with no need for forced air cooling.
