Model xx : V2 second optional Voltage ( +5V - +48V ). Ex: +12V , xx : 12.
*Dual output V2 Forced air 20W, convection cooling need to drop to 15Wmax.
Note:
  • Ripple and noise on +12V rail is 180mV max. , 280mV for +24V and 380mV for +48V. They are measured at oscilloscope 20MHz bandwidth by a 100uF electrolytic capacitor and a 0.1uF ceramic capacitor in parallel at output wire 300mm length connector.
  • Output regulation for +12V is ±3% and ±2% for +24V and +48V( -1~-20°C ambient temperature and EMS Immunity worst case ≦5% ).
  • B-Type 150W Max.( Input 90-120Vac) and 170W Max.( Input 200-264Vac) Convection or 250W Max. forced air cooling.
    U-Type and E-Type 160W Max.( Input 90-120Vac) and 190W Max.(Input 200-264Vac) Convection or 250W Max. forced air cooling.
    T-Type with TOP mounted FAN 250W Max. Convection, T-Type provide single output only.
  • V2 : FN model provide +12V Fan voltage, voltage range : ±8% ( +12V Main output , FAN Voltage range: +10V~+12V)
  • Dual output model Second output ( V2 ) : Optional Voltage , XX : Optional Voltage +5V ~ +48V , 20W Max.
  • The switching frequency of this series is set 80 to 100KHz at full load.
