The VY and VR series were developed to minimize the noise associated with switching ICs. Kaga Electronics/Volgen has developed units with ripple noise less than 10 mVp-p and the VR series is as low as 3 mVp-p. These units also have a 5-sided metal case, short circuit/over-current protection and over heat protection. Please refer to the application notes on the use and installation of these units.
