Contact The Factory For Details Notes: 1. Output voltage tolerance is measured at nominal input and 75% load. 2. Output ripple is measured at 20 MHz bandwidth using 0.1 µF and 10 µF capacitors connected in parallel as close to the power supply terminals as possible. 3. These units will operate at no load without damage. For most applications however, MPD recommends that a minimum load always be used. Contact the factory for more information. 4. Each unit includes an input fuse (250V/2A). Since this fuse is not field replaceable, it is recommended that an external fuse of the same size be used on the input of the power supply for protection. Mechanical Dimensions Pin Connections Pin 1 2 3 4 5 6 Description AC-Neutral AC-Line +V Output +V Output -V Output -V Output Safety Ground: The mounting holes marked “Use metal standoffs” should be connected to the system earth ground via metal spacers or a cable. The input side mounting hole marked “FG” provides the safety earth ground for the unit. This connection should be locked to prevent possible loosening. Connecting the output side mounting hole improves EMI.
