1. Parallel Operation
The VFK600 series are designed for parallel operation. When in parallel the load current can be shared equally between the two
modules by connecting their PC pins. The VFK600 can be setup in two different modes to achieve parallel operation. The stan
dard parallel operation is suitable when load cannot be handled by a single unit, whereas the N+1 redundant operation is suitable
for loads when backup power is required.
