Cover kits are offered for the Artesyn NLP250, Artesyn TLP150, and Astec LPS120 series of AC-DC power supplies. Until now, the power supplies have only been available in open-frame, or non-enclosed, versions. The cover kits are designed to simplify mechanical integration of the power supplies into systems, and add an extra measure of electrical safety for service personnel. All three cover kits are available as separate add-on accessories, and the Artesyn NLP250 power supply can optionally be ordered with the cover pre-installed at the factory. Featuring robust, ventilated enclosures, the cover kits are supplied complete with all necessary insulating plates, mounting brackets, and screws.
