This version uses a 1\"-2\" Single Foot housing with isolated ground and a side battery connection. It is intended for installations where the alternator, engine mounting and belt drive are selected together to meet the battery bank’s charging requirements.\u003c\/p\u003e\n\u003cp\u003eHeat-management features include twin cooling fans, an externally positioned rectifier and a heat-shedding finish. These features support sustained charging while the engine is running, with the final output depending on alternator speed and operating temperature.\u003c\/p\u003e\n\u003cp\u003eThe Low Turn On (LTO) design is aimed at charging at lower engine speeds. It uses a native 24V rotor and is the Zeus option intended for owners who prioritise idle-speed charging or need to limit engine power take-off.\u003c\/p\u003e\n\u003ch3\u003eFeatures and benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for charging substantial battery banks in marine and other mobile electrical systems.\u003c\/li\u003e\n\u003cli\u003eDual fans and an external rectifier help dissipate heat during charging.\u003c\/li\u003e\n\u003cli\u003eExternal regulation allows the charging profile to be matched to the battery system.\u003c\/li\u003e\n\u003cli\u003eTMS recommends the ARCO Zeus Bluetooth regulator for lithium charging and for control of alternator performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct code:\u003c\/strong\u003e AZ4405\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal voltage:\u003c\/strong\u003e 24V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput class:\u003c\/strong\u003e 4kW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e 1\"-2\" Single Foot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround configuration:\u003c\/strong\u003e Isolated Ground\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery post position:\u003c\/strong\u003e Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePulley:\u003c\/strong\u003e 49mm K6, six grooves\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulation:\u003c\/strong\u003e External only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eField type:\u003c\/strong\u003e P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor poles:\u003c\/strong\u003e 16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStator diameter:\u003c\/strong\u003e 138mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut-in speed:\u003c\/strong\u003e 1,072 alternator rpm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum alternator speed:\u003c\/strong\u003e 19,000 rpm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum continuous operating temperature:\u003c\/strong\u003e 100°C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatibility and installation\u003c\/h3\u003e\n\u003cp\u003eMatch the bracket spacing, ground arrangement, belt profile and pulley alignment to your engine.
