Have used this exact model at work for a number of customer installs along with the iswebcard and the gxt448batt expansions with great success and i needed a better unit than the 1500va consumergrade unit i currently run in my project rack

It still has the usual banks of 520r outlets on the back bank 1 bank 2 and general that are compatible with all 15a straightblade plugs

Overall these units are very well built
