What is a VW3A16902 option board?

The ATV16 type drive is obsolete.

This was called the Voltage Doubler Option and was only used with the ATV16U09M2 and ATV16U018M2 208 vac single phase input units.

The option allowed a user to provide 115 vac single phase as the input power.  The module would then doubled the effective voltage to 290 vdc, which was wired to the drive`s DC bus terminals.

The option`s enclosure was rated for IP00 protection and had to be enclosed by the customer.
