Sizing Guide

When is 50 kVA the right choice?

50 kVA is the right starting point for an electronics assembly unit, a small injection moulding shop with one or two machines, or a printing press running a single 4-colour offset. At 50 kVA, air cooling is sufficient — the heat load stays well within what natural convection can handle without fans, making it a quieter and more maintenance-free installation than oil-cooled units of larger size. This rating is also common as a dedicated stabilizer for server room isolation in manufacturing plants, where the IT load (UPS input, switches, cooling) is kept on a separate protected circuit away from the main production feeder.
