The transaction had a price-tag of USD 9 million in cash plus USD 1 million in escrow pending realisation of certain sales targets.

NPS, which specialises in high quality, advanced technology DC power systems for use in networking, telecommunications, and high-speed data transmission, was acquired by Bel as part of its approximately USD 117 million purchase of Power Solutions from ABB in June 2014.

"This divestiture will allow us to focus exclusively on Power Solutions' core product groups--Front End, Industrial and Board Mounted Power--as we work to develop Bel's global power business, a key element of our strategy to enhance growth and profitability for our shareholders," said Daniel Bernstein, Bel's President and CEO.

The transaction provides that Bel will move processes and people to Unipower under an interim transition agreement. Bel also will continue to manufacture the NPS products for up to 24 months under a manufacturing agreement.
