Features, Applications

Open Frame with Optional Cover Designed to meet UL, CSA, and TUV safety standards

The SWB Series features Sanken' s proprietary resonant-mode power hybrid IC and transformer. These models provide the high efficiency and low noise that can only be realized with a resonant-mode supply. These supplies can accept an input voltage range 264 V, and feature continuous input operation which requires no manual voltage selection. Their design makes it easy to meet the power supply needs of world-wide applications.

Note 1: At cold start. (More current may flow at restart.) Note 2: Ripple noise is measured with a 100 MHz oscilloscope, using a 1:1 probe. Note 3: Output characteristics are measured at the output connector. Ripple noise is measured at a point 5 cm from the output connector, with 47 F electrolytic capacitor attached at that point. * "Rated input/output conditions" means that the switching power supply is operated under the rated input voltage, rated output voltage, rated output current, rated frequency, and at an ambient temperature of 25C and 60% humidity.
