Quasar series

Bi-directional power supply with power factor correction

With the Quasar B1-400/6, Prodrive Technologies offers a matching supply for the Cygnus D3-400/4 series of servo drives. Quasar power supplies feature an internal power factor correction circuit which significantly reduces the input current compared to traditional drives with an input rectifier. In addition to this, select models in the quasar series are capable of bi-directional power flow, which increases overall efficiency and saves cost on external brake resistors.
