Challenge placed some $2 million, Vertex invested about $1.8 million, and the rest came from Clal.
This completed PowerDsine's fifth round worth $30 million at a $105 million post-money value.
In November PowerDsine announced it had completed a private placement of $25 million at some $100 million post-money company value.
PowerDsine develops software-based solutions for delivering operating power on voice-data and telecom communications networks.
At the time PowerDsine said that this was the round's first stage and that it intended to expand it in the coming period.
CEO Igal Rotem said that the proceeds would suffice for fully financing the company's business plans, and that the round is expected to be the last before going public.
