It has Soft-start, a soft and delayed start-up system that analyzes the loads that exist at the unit's output to gradually supply the required voltage, reducing the unit's consumption. Includes LED display that indicates current consumption. Great reliability complying with TUV certification. MODIFIED WAVE The modified wave generates an output of small square waves that, when added together, create an envelope that simulates a pure sine wave. This type of equipment covers a wide range, including computer systems and lighting. Its response to the presence of consumption peaks is very fast. On the other hand, the correct functioning of equipment that incorporates electronic or digital circuits, such as timers, intensity regulators, automatons or frequency variators, may be affected.
