TSO'd REGULATED AC TO DC OFF-LINE CONVERTER

(115 Vac to 7.5 Vdc Fixed Output)

PFA1Description:

  • The PFA1 is a pulse width modulated ac to dc off-line converter that provides regulated 7.5 Vdc power up to 1.34 amperes.The output voltage is adjustable ± 1 volt by an internal trim pot and factory set to 7.5 Vdc at 1.34 amperes.The PFA1 output is isolated from H.V. input.
  • The PFA1 output is current limited.
