    There is no external fuse in the unit, a safety fuse is installed inside the unit. In event of fuse blown, the fuse must be replaced only by Scientific authorised service personal. When power supply unit is switched ON, its inrush current is limited by internal circuitry. Switching ON and OFF at faster rate, may result in over heating of current limiter, resulting higher inrush current.
