Small footprint power supplies 3. The V Series and M Series are optimal forM Series is 20.9cm are extended to 3-kV handheld devices and lightweight systems. Typical applications UltraVolt’s has increased the voltage levels of its V Series and include avalanche M Series of microsize, micropower products by up to 100%. photo diodes (APD), V Series and M Series modules are now offered at 0 to 2kV, photomultiplier tubes 0 to 2.5 kV, and 0 to 3 kV with 5, 12, and 24 V inputs. These (PMT), X-ray imag- new extended voltages also come with an Enhanced Interface ing sensors, Pockels (EI) Option, which adds a current monitor and enable pins. V cell, q-switches, and Series and M Series modules offer programmable regulated micro-channel plates. output, high accuracy, and low ripple (0.01% peak to peak). The UltraVolt volume for the V Series is just 13.8cm3, and the volume for the www.ultravolt.com rated lED power supplies Efficient POWERatt IP67-w150 and 200 LED and LDB 200 power supplies SOLUTIONS Excelsys Technologies’ LDB 150 provide 150 watts and 200 Watts of from the wall to the point of load TM 10W~400 W constant current/constant voltage power respectively in an IP67 rated, low profile, aluminium case. Digital Power Modules Measuring only 198x63x35mm with Intermediate Bus l Point of Load the UL8750 and CE markings, the LDB150 and LDB 200 series each feature two models offering 24V or 48V nominal output voltages. The 0.25 W~600 W units offer constant voltage operation up to their full load capability and Dc-Dc Converters then constant current operation Board Mount l Chassis Mount down to 50% of their nominal output voltage. An extended universal AC input range of 90-305VAC with active power factor correction with high efficiency operation up to 92.5% make these units ideal 1W~2400 W for “green” lighting applications. Additional features include -30 Ac-Dc Power Supplies to +70°C operating temperature, Open Frame l Chassis Mount l External built-in over-current protection, over-voltage protection, over temperature protection and short- circuit protection high line and load regulation, an MTBF of 1,000,000 hours per Telecordia SR-33 and With a continuous focus oneffi ciency, density, andsystem optimization, both models are backed by a 5 year we keep our customers on theleading-edge of the power curve. warranty. Custom output voltage and output current set-points are available for OEM applications.
