Specialists in softstarter technologies

A CDC Dynamics boast a full product offering in low voltage soft starters from 7 kW to 500 kW and in medium voltage from 2.3 kV to 13.8 kV up to 1.7 MW. With an exclusive focus on soft starters, AuCom expertly develops a range of industry-lead- ing control products for industrial applications. Take control from the start The L-Series MVE soft starter is packed with fea- tures including real-language feedback messages, built-in monitoring systems and indicators, together with extensive on-board input and output function- ality. Real-time graphs showing motor operating performance and current quickly and clearly illus- trate motor performance. Powerful and reliable Variables such as altitude, ambient temperature, load and starts per hour all affect selection of the ideal motor starting solution. Aucom employs so- phisticated engineering tools to assist in selecting the right MVE starter for unique site conditions. • A design based on standard components re- duces the need for spare parts and simplifies- support. • An ultra-compact form factor supports vertical or horizontal integration of power electronics, saving valuable space. • Individually removable phase arm design allows for simple installation, service or replacement. • Conformal coating on PCBs for protections in environments up to pollution degree 3 • Shorter lead times owing to a design that lends itself to more automated manufacturing- processes. • Status LEDs for immediate feedback. • Intuitive interface and menu structure for easy setup, with multi-level password protection. • IP54 keypad mounted on cabinet exterior. Panel details L-Series MVE panels are available in either IP4X or IP54 panels, with options for line and bypass devices, as well as earthing and isolation switches.

AuCom can also design and build panels to meet particular specifications, and offers full application engineering support at all stages of the design pro- cess. For customers who prefer to build their own panels, MVE soft starters can be supplied in IP00 format or as a kit for local assembly. Multi-motor solutions are also available for coordinated control of up to four motors. Arc fault Arc faults can occur for a number of reasons includ- ing over voltage, faulty insulation, mechanical failure or failure of a fuse. If an arc event occurs within an AuCom L-Series panel, the fault is contained by solid locking doors and heavy double-layer compart- ment panels. During the emission phase, the pres- sure is safely released using discharge flaps on the top of the panel (or optional ducts), which direct the explosion upwards or vent it safely outside. Even safer with IBT technology AuCom Interface Board Technology (IBT), a unique concept within the medium voltage soft starter- market, separates the core starter control system (including the starter’s HMI and complex, time crit- ical algorithmic processing) from the medium volt- age power section. The interface board is located within a separate, section of the internal arc tested medium voltage compartment. Fibre optic wires connect the control and power sec- tions of the starter through the interface board, eliminating the need for any copper wiring and providing complete galvanic iso- lation of the low voltage compartment.
