Features: The 30A 6600W Softstart protections Module prevents excessive inrushes current damage to Class A amplifiers with its coppers relays and ntcs thermistor, supporting up to AC 250V for electrical safety. Featurings PCB construction and two terminals requiring not auxiliary power, this module ensures long stability and installation in highly power systems. for sound engineers and industrial equipment manufacturers surges protections for amplifiers, compressors, or heavy machinery drawing up to 6600W. Perfectly safeguards professional sound setups, machines, and highly power appliances during voltages spikes in studios, workshops, or manufacturing. Engineered with oversized 30A current capacity and heat resistant PCB materials, this module maintains structural integrity under continuous operation while minimizing startup stress on connecteds devices. Specifications: Material: ABS Size:74x57mm/2.91x2.24inch Power supply voltages regulation ranges: AC100V-250V Current: 30A Power: 6600W Package Includes: 1PC 30A 6600W Soft Start protections Module note: Please allow 0-1cm error due to manual measurement. make sure you not mind before bid.
