  8. Lighting Market • Capacitance up to 60mF • Voltage up to 1000Vac • Temperature up to 100°C • UL recognized internal protection • External discharge resistor

  9. Air Conditioning/Motor Run • Room Air Conditioners • HVAC Aftermarket Distribution • Motor/Compressors • HVAC Unitary Equipment MFG’s • Refrigeration/Laundry Equip • Miscellaneous/Ice Equip MFG’s • LVPF (Low voltage power factor)

  10. Air Conditioning/Motor Run • Capacitance up to 100 mF • Single & Dual ratings available • Voltage up to 660Vac • Temperature up to 70°C • Frequency 50-60Hz • UL Recognized internal protection

  11. Motor Start Capacitors Pressure safety vent 2 blade quick connect terminals • Moisture and Oil Resistant Case Requiring No Insulation • Bleeder Resistors, Caps, and Brackets Available Type PSU

  12. Type PSU Motor Start • Voltages: 125, 165, 250, 330 Vac • Capacitance: 21 to 1200 mF • Temperature -40 °C to +65 °C • Frequency: 50 to 60 Hz • Aluminum Electrolytic • Non Polarized

  13. Type PSU • For intermittent AC use in starting of split-phase motors • Cap specified as a range • Example: 21 - 28 mF • Type I for garage door openers good for 75,000 starts. • Type II for general purpose motor start - good for 50,000 starts

  14. Markets Home Appliances Industrial equipment Motor Manufacturers Applications Electric motor starting Starting for split phase motors Garage door openers Type PSU Motor Start

  15. DC/AC Rated Type OTB • Dual rated for DC/AC Solder lug terminals with insulator cup Metal case Protected with an Internal pressure interrupter Paper, film & foil Impregnated construction Type OTB

  17. Market Areas High voltage power supplies Power amplifiers EMI/RFI Filters Motors Applications Input / Output filtering Blocking & bypass Filtering Power factor correction Type OTB DC/AC Dual Rated

  18. Commutation / Snubber • Type SCR and SNU Ceramic insulated screw terminals Solder lug terminals with insulator cup Metal case with Non ferrous covers optional Aluminum Case Type SNU Type SCR

  19. Commutating Capacitors • Commutating in layman terms • Is a reduction in severity of a punishment by law. • Commutating in electrical terms • A reversal of current direction or the conversion of alternating current to unidirectional current • The cap takes the heat off the SCR

  20. Type SCR and SNU Comparison * This rating only, all the rest are 60 A

  21. Type SCR and SNU • Threaded studs on the SCR give the higher current rating • The SNU aluminum case is ideal for welding applications where current flowing thru the capacitor creates a magnetic field that heats ferrous materials

  22. Markets Power Conversion Applications Welders Power Supplies Type SCR and SNU

  23. DC Rated Capacitors Ceramic insulated screw terminals Hermetically sealed metal case Type T

  24. Type T Filter Capacitors High Voltage • 600 Vdc 0.50 to 15.0 mF • 1000 Vdc 0.10 to 15.0 mF • 1500 Vdc 0.50 to 15.0 mF • 2000 Vdc 0.10 to 15.0 mF • 2500 Vdc 1.0 to 4.0 mF • 3000 Vdc 0.1 to 6.0 mF • 5000 Vdc 0.50 to 2.0 mF
