Using Smart-Boost digital control technology, it can deliver up to \u003cstrong data-end=\"549\" data-start=\"500\"\u003e600 percent additional current during startup\u003c\/strong\u003e, giving demanding motors the surge they need to start cleanly and reliably.\u003c\/p\u003e\n\u003cp data-end=\"897\" data-start=\"627\"\u003eThis system is built for serious equipment that pushes beyond the limits of standard rotary phase converters. If motors downstream struggle to start, stall under load, or require repeated attempts to come online, the SB-20 is designed specifically to address that issue.\u003c\/p\u003e\n\u003chr data-end=\"902\" data-start=\"899\"\u003e\n\u003ch3 data-end=\"951\" data-start=\"904\"\u003eDesigned for Heavy Industrial Startup Loads\u003c\/h3\u003e\n\u003cp data-end=\"1264\" data-start=\"953\"\u003eThe SB-20 is well suited for larger hard-starting motors used in air compressors, submersible pumps, flywheels, gearhead lathes, and other high-inertia three-phase equipment. These machines often demand far more current at startup than during normal operation, which is where conventional converters fall short.\u003c\/p\u003e\n\u003cp data-end=\"1454\" data-start=\"1266\"\u003eSmart-Boost technology actively supports these moments by delivering extra current only when needed, helping motors overcome initial resistance without overstressing the electrical system.\u003c\/p\u003e\n\u003chr data-end=\"1459\" data-start=\"1456\"\u003e\n\u003ch3 data-end=\"1502\" data-start=\"1461\"\u003eHow Smart-Boost Digital Control Works\u003c\/h3\u003e\n\u003cp data-end=\"1824\" data-start=\"1504\"\u003eAt the core of the SB-20 is a Smart-Boost digital controller that uses solid-state relays to re-energize start capacitors at \u003cstrong data-end=\"1670\" data-start=\"1629\"\u003ezero-degree crossing on the sine wave\u003c\/strong\u003e.
