The terminals are clearly marked on the casing according to the electrical diagram: three inputs for AC phases and two outputs for positive and negative DC. Installation is done by mounting it on a metal surface for additional heat dissipation and connecting the conductors to the corresponding terminals, observing the indicated polarity. The finned heatsinks dissipate heat through natural convection, without moving parts.\u003c\/p\u003e\n\n\u003c\/section\u003e\u003csection class=\"cl-faq\"\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs forced fan cooling necessary for continuous operation at 40A?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eNo, the integrated aluminum heatsink provides sufficient thermal dissipation through natural convection for operation at nominal current, provided it is mounted on a metal surface for additional heat evacuation.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I connect the bridge directly to a 380V three-phase network?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, the bridge supports standard industrial three-phase input voltages, but the DC output voltage will be proportional to the RMS value of the AC input, reaching approximately 540V DC for 380V AC three-phase.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat cable cross-section is recommended for connecting the terminals at 40A?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eFor a nominal current of 40A, cables with a minimum cross-section of 6 mm² copper are recommended, ensuring a thermal safety margin and limiting ohmic losses on the conductors.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003c\/section\u003e\u003csection class=\"cl-specs\"\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eModel\u003c\/td\u003e\n\n\u003ctd\u003eSQL-4016\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConfiguration Type\u003c\/td\u003e\n\n\u003ctd\u003eThree-Phase Rectifier Bridge\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMaximum Current\u003c\/td\u003e\n\n\u003ctd\u003e40A\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMaximum Inverse Voltage\u003c\/td\u003e\n\n\u003ctd\u003e1600V\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eNumber of Input Phases\u003c\/td\u003e\n\n\u003ctd\u003e3 AC Phases\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConversion Type\u003c\/td\u003e\n\n\u003ctd\u003eThree-Phase AC to DC\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eNumber of Terminals\u003c\/td\u003e\n\n\u003ctd\u003e5 faston connectors\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eCasing Material\u003c\/td\u003e\n\n\u003ctd\u003eAluminum with heatsinks\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\n\u003ctd\u003e98 x 60 x 53 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eCooling Type\u003c\/td\u003e\n\n\u003ctd\u003ePassive by heatsinks\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eConformity Marking\u003c\/td\u003e\n\n\u003ctd\u003eCE\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003c\/section\u003e\u003csection class=\"cl-warranty\"\u003e\u003ch2\u003eWarranty and Support\u003c\/h2\u003e\n\n\u003cp\u003eThe product benefits from a 24-month legal conformity warranty in accordance with Romanian legislation. 30-day return policy from receipt for unused products.
