How much capacitance is on the power supply's output?

  • Knowledge Base ID: 1007
  • Product Type: MagnaDC
  • Category: Hardware

High frequency switch-mode power supplies, such as Magna-Power's MagnaDC product line, use large banks of electrolytic capacitors to filter output ripple. The amount of capacitance used varies by the unit's peak output voltage rating. Table 1 provides the standard amount of output capactiance used in the SL Series. Table 2 provides the standard amount of output capacitance used in the XR Series. Table 3 provides the standard amount of output capacitance used in the TS Series​. Table 4 provides the standard amount of output capacitance used in the MS Series​. For information about the MT Series products, please contact support. Units with the High Slew Rate (+HS) option will have a lower amount of capacitance, which is detailed in the option page link from the respective product pages.
