June 4th, 2014, Published in Articles: Vector


acdc-303-06-2014Emerson Network Power has announced the LDS100 series high-efficiency power supplies for LED lighting, bringing to three the distinct power output bands covered by its LED lighting products: 25, 70 and 100 W. The 100 W power supplies offer a choice of models featuring ranges of 120 – 277 V AC (H models) and 100 – 240 V DC (U models). The first models in the series feature Class 2 outputs delivering up to 4,1 A at 24 V DC and offer both constant current and voltage output modes. Constant voltage mode operates from no load to full load and the LDS100-24-H03 model features programmable current limit levels controlled via an IEC 60929 compliant interface using standard 0 – 10 V signal to aid dimming. The current limit level is also resistor programmable and can be preset by the system designer. The company’s power supply models feature active power factor correction rated 0,9 and meet the class C harmonic requirements of IEC 61000-3-2. Arrow Altech Distribution represents Emerson Network Power in South Africa.
