Payne Controls Co. (formerly Payne Engineering) has redesigned several of its model 18DZi single-phase power controls to offer zero-fired control in a more compact and isolated chassis design. The redesign makes the new models physically interchangeable with the Model 18Di series phase-angle fired power controls. The new controls are said to provide silent proportional control of AC voltage to the constant resistance loads without noisy, arcing contacts, brushes or maintenance-prone moving parts. The control units incorporate the company’s “self-protecting” design to protect from potentially destructive conditions commonly encountered in industrial applications such as semiconductor protection from load fault over-current damage; transient voltage spikes; and a new heat sink chassis using convection cooling for full-rated operation in ambient temperatures to 122ºF (50°C) without fans.
