This exact CYR020400000 is the 24\/48V version, rather than the separate 12\/24V model.\u003c\/p\u003e\n\u003c\/div\u003e\u003csection style=\"margin:26px 0;padding:28px;color:#0B1220;line-height:1.7;\"\u003e\u003ch3\u003eMatch both banks to the same nominal voltage\u003c\/h3\u003e\n\u003cp\u003eAutomatic 24V\/48V selection supports an input range of 16–72V DC. It does not convert 24V into 48V and must not be used to directly parallel banks with different voltages. Match the charger settings, battery chemistry and installation design before selecting a combiner.\u003c\/p\u003e\n\u003ch3\u003eSeparate continuous and momentary ratings\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer rates this model for 400A continuously and 2000A for one second. Check the entire current path, including cables, fuses, terminals and battery capability. The momentary rating is not a continuous load allowance, and the relay does not impose a charging-current limit on an alternator or other source.\u003c\/p\u003e\n\u003ch3\u003eFollow charging behavior in either direction\u003c\/h3\u003e\n\u003cp\u003eThe Cyrix-i senses voltage on both sides and follows voltage trends and programmed timing to decide when to connect or separate the banks. Four selectable timing profiles allow the installer to choose an appropriate response for the charging arrangement. This avoids relying on a simple instantaneous voltage threshold alone.\u003c\/p\u003e\n\u003ch3\u003ePlan controls and status access\u003c\/h3\u003e\n\u003cp\u003eA bicolor LED provides status information, and a microswitch supports remote monitoring. A separately selected external control can request an approximately 30-second start-assist parallel connection. Wire these functions to the official diagram; monitoring and control circuits do not replace the required protection in the main battery circuit.\u003c\/p\u003e\n\u003ch3\u003eAllow room for a substantial battery connection\u003c\/h3\u003e\n\u003cp\u003eDimensions are 78 × 102 × 110mm in height, width and depth, with an approximate weight of 0.9kg. Open-state current draw is under 4mA. Provide a protected installation location, suitable access and terminal insulation according to the manual. Plan the cable routing before choosing the mounting position.\u003c\/p\u003e\n\u003ch3\u003eWhat is included?\u003c\/h3\u003e\n\u003cp\u003eOne exact CYR020400000 Cyrix-i 24\/48V-400A battery combiner. Batteries, main cables, fuses, switches and other installation equipment are separate. The photo identifies the 24\/48V version; do not use the similar family name to select the 12\/24V part.\u003c\/p\u003e\n\u003ch3\u003eWhen is a DC-DC charger a better match?\u003c\/h3\u003e\n\u003cp\u003eChoose a suitable DC-DC charger when the installation needs regulated charging, deliberate current limiting or conversion between different battery voltages. A combiner joins compatible banks under defined conditions. It does not provide those charger functions or replace a battery management system.\u003c\/p\u003e\n\u003ch3\u003eBuild the complete equipment list first\u003c\/h3\u003e\n\u003cp\u003eCompare bank voltage, battery chemistry, source behavior, normal charging current and expected starting demand before ordering. For lithium or mixed-chemistry systems, confirm the required BMS control and charging approach with the equipment manufacturers. A high relay-current rating by itself does not establish compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/accessories\"\u003eCompare power accessories\u003c\/a\u003e · \u003ca href=\"\/pages\/power-planner\"\u003ePlan your battery system\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.victronenergy.com\/upload\/documents\/Datasheet-Cyrix-i-400A-EN.pdf\"\u003eManufacturer specifications and installation guidance\u003c\/a\u003e · \u003ca href=\"\/pages\/contact\"\u003eAsk Torven Power about compatibility\u003c\/a\u003e\u003c\/p\u003e\u003c\/section\u003e\u003c!-- TORVEN_DESCRIPTION_END --\u003e\u003c!-- TORVEN_SPECIFICATIONS_START --\u003e\u003csection style=\"margin:26px 0;padding:28px;border:1px solid #E5E7EB;border-radius:14px;background:#FFFFFF;\"\u003e\u003cp style=\"margin:0 0 8px;color:#DEA61D;font-size:13px;font-weight:800;letter-spacing:1.2px;text-transform:uppercase;\"\u003eProduct Data\u003c\/p\u003e\n\u003ch2 style=\"margin:0 0 14px;color:#0B1220;font-size:26px;line-height:1.25;\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;border:1px solid #E5E7EB;border-radius:12px;\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-size:15px;\"\u003e\n\u003cthead\u003e\u003ctr style=\"background:#0B1220;color:#FFFFFF;\"\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eManufacturer\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eVictron Energy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eExact SKU\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eCYR020400000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eVersion\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003e24\/48V automatic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eInput voltage range\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003e16–72V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eContinuous current\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003e400A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eMomentary rating\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003e2000A for 1 second\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eTiming profiles\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eFour\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"padding:14px 16px;text-align:left;\"\u003eStart assist\u003c\/th\u003e\n\u003ctd style=\"padding:14px 16px;\"\u003eApproximately 30 seconds;
