APPLICATION NOTES
1. Parallel Operation
The VFK600-DIN 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-DIN can be setup in two different modes to achieve parallel operation. The
standard 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.
