DGP Automatic Transfer Switch (ATS) is a single Phase Dual
Input rack mountable Power Distribution Unit (PDU).
When Input A falls below 168 VAC and Input B is valid, the
output is automatically transferred to Input B. The output
is transferred back to Input A when Input A is valid and
rises above 178 VAC. This high speed transfer rate ensures
that the transfer is transparent to the sensitive equipment.
The two sources are not required to be in phase. This is an
effective solution that builds in redundancy and increases
the AC power availability of connected equipment. If the
dual input power is fed through two independent AC sources,
then the system availability is increased and the dual input
advantages are fully used.
