The figure below ia a suggested diagram to reduce Electromagnetic Interference (EMI). C1 = Electrolytic Capacitor Capacitance = 22uF - 220uF Voltage = Two times rated output voltage L1 = 3uH - 10uH C2 = Electrolytic Capacitor Capacitance = 22uF - 47uF Voltage = Two times rated output voltage C3 = Ceramic Capacitor Capacitance = 0.01uF - 0.1uF Voltage = 50 volt Notes: 1. The use of C1 alone may reduce noise to desired levels, if not use L1, C2 and C3 in addition to C1. 2. The figure above is a suggested circuit. Only by trying true application can levels be tested. C1 = 0.22uF X Capacitor L1 = 10mH - 30mH Common Mode, Choke C2, C3 = 220pF Y Capacitors Notes: The diagram above is a recommended circuit, only by trying true application can levels be measured. Inrush Current If desired, the use of a Choke, NTC or Inrush Current Limiter may be used to reduce the Inrush Current www.ASTRODYNE.COM 300 Myles Standish blvd., Taunton, MA 02780 ph: 1-800-823-8082 Fax: 508-823-8181 |
