It is designed to provide a dedicated charging solution for a secondary battery on board.\u003c\/p\u003e\u003cp\u003eThe Charge Mate Pro effectively distributes the charger or alternator current between two battery banks, such as a starter and a service battery. It connects both batteries during charging and keeps them isolated when discharging, reducing the risk of a flat starter battery.\u003c\/p\u003e\u003cp\u003eThis charge relay offers an advantage over mechanical charge relays by limiting the charge current to the second battery. The primary battery, like a starter battery, is charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the Charge Master Pro.\u003c\/p\u003e\u003cp\u003eAn example of a marine application for the Charge Mate Pro is the connection of a bow thruster battery to a service battery. It ensures that the service battery is always charged with priority and blocks the return current from the bow thruster battery, guaranteeing that the bow battery remains charged. The current limiting feature also prevents power dips in the onboard electrical network.\u003c\/p\u003e\u003cp\u003eThe Charge Mate Pro series consists of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications.\u003c\/p\u003e\u003ch2\u003eFeatures:\u003c\/h2\u003e\u003cul\u003e  \u003cli\u003eElectronic charge coupling with very low voltage drop\u003c\/li\u003e  \u003cli\u003eMakes effective dual charging possible\u003c\/li\u003e  \u003cli\u003eSuitable for all battery types, including Lithium Ion\u003c\/li\u003e  \u003cli\u003eCharge current secondary battery limited to 40 A\u003c\/li\u003e  \u003cli\u003eHigh system reliability by prioritized charging of the main battery\u003c\/li\u003e  \u003cli\u003eUnidirectional which blocks return current under all circumstances\u003c\/li\u003e  \u003cli\u003ePrevents power dips of the onboard electrical network\u003c\/li\u003e  \u003cli\u003eSuitable for all kinds of chargers and alternators\u003c\/li\u003e  \u003cli\u003eMonitoring with LED status indication\u003c\/li\u003e  \u003cli\u003eIP65 electronics in a corrosion resistant casing with aluminum heat sinks\u003c\/li\u003e  \u003cli\u003eFast and easy installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGeneral Specifications:\u003c\/h2\u003e\u003cul\u003e  \u003cli\u003eRemote switch functions: on, off, auto, start assist\u003c\/li\u003e  \u003cli\u003eMonitoring: LED (warnings and status indication)\u003c\/li\u003e  \u003cli\u003eOutput current: limited to 40 A\u003c\/li\u003e  \u003cli\u003eNumber of battery outlets: 2\u003c\/li\u003e  \u003cli\u003eInput voltage range: 9-32 V\u003c\/li\u003e  \u003cli\u003eParallel configuration: yes\u003c\/li\u003e  \u003cli\u003eBattery voltage: automatic 12\/24 V detection\u003c\/li\u003e  \u003cli\u003eDimensions (hxwxd): 157 x 140 x 80 mm \/ 6.2\" x 5.5\" x 3.1\"\u003c\/li\u003e  \u003cli\u003eWeight: 0.88 kg \/ 1.9 lb\u003c\/li\u003e  \u003cli\u003eApprovals: CE\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications:\u003c\/h2\u003e\u003cul\u003e  \u003cli\u003eConnection possibilities: 3 x fast-on connectors (switch, ground, and status)\u003c\/li\u003e  \u003cli\u003ePower consumption: switch open: \u0026lt; 1 mA at 12\/24 V DC\u003c\/li\u003e  \u003cli\u003eBattery types: all types (Lithium Ion protection via Multi-purpose contact, product code 77030500)\u003c\/li\u003e  \u003cli\u003eSwitch on voltage: 13.5 V (12 V) \/ 27 V (24 V)\u003c\/li\u003e  \u003cli\u003eSwitch on delay: 5 sec.\u003c\/li\u003e  \u003cli\u003eSwitch off voltage: 12.75 V (12 V) \/ 25.5 V (24 V)\u003c\/li\u003e  \u003cli\u003eSwitch off delay: 2.5 sec.\u003c\/li\u003e  \u003cli\u003eRelay: electronically (mosfets with low voltage drop of max 0.2 V)\u003c\/li\u003e  \u003cli\u003eTemperature range (ambient temp.): -40 \u0026amp;degC to 60 \u0026amp;degC (-40 to 140 \u0026amp;degF)\u003c\/li\u003e  \u003cli\u003eProtection degree: IP65\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLearn More:\u003c\/h2\u003e\u003cp\u003eFor more information about charge relays, you can visit the \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Charge_relay\" onclick=\"window.open(this.href, 'popup', 'height=600,width=800'); return false;\"\u003eWikipedia page on charge relays\u003c\/a\u003e.\u003c\/p\u003e\u003cp\u003eTo learn more about Mastervolt, the manufacturer of the Charge Mate Pro 40 Electronics Relay, you can visit their \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Mastervolt\" onclick=\"window.open(this.href, 'popup', 'height=600,width=800'); return false;\"\u003eWikipedia page\u003c\/a\u003e.\u003c\/p\u003e","brand":"Mastervolt","offers":[{"title":"Default Title","offer_id":48077367345473,"sku":"0852968002981","price":251.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/3372\/1153\/files\/CWR-68306_0852968002981_image1.jpg?v=1758743652","url":"https:\/\/www.atlantisshowroom.com\/products\/mastervolt-83304002-charge-mate-pro-40-electronics-relay","provider":"Atlantis Showroom","version":"1.0","type":"link"}
