\u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   The DD30CRTA is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   The DD30CRTA is specially designed for charging 12V lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   In over-charge and float charge mode, the regulation voltage is internally set.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   The constant charge current is programmable with a single sense resistor.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   constant charge current until the cell voltage exceeds 75% of the regulation voltage in\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   over-charge mode. The over-charge is terminated once the charging current drops to 38% of the\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   constant charge current, then DD30CRTA will enter float charge mode. A new charge cycle\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   automatically restarts if the battery voltage falls below 83.95% of the over-charge voltage in\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   float-charge mode. DD30CRTA will automatically enter sleep mode when input voltage is lower than battery voltage.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   Other features include undervoltage lockout and status indication, etc.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   The Regulation Voltage in Over Voltage Mode and Float Charge Mode\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   The regulation voltage VOC at BAT pin in over charge mode is set at 14.8V(Typical) with ±1.5% accuracy.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   In float charge mode, the regulation voltage VFLOAT at BAT pin is 91.57% of that in over charge mode, which is 13.55V(Typical).\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   Trickle Charge Mode At the beginning of a charge cycle, if the battery voltage is below 75%×VOC, the charger goes into trickle\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   charge mode with the charge current set at about 17.5% of the constant current.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   End-of-Over Charge Current\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   When the battery voltage approaches the over-charge voltage, the charger goes into the over charge mode. In\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   over charge mode, the charge current start to decrease and when the charge current drops to 38% of constant\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   charge current, the charger goes into float-charge mode.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   Float Charge Mode\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   After the over voltage charge is terminated, the charger goes into float charge mode. In float charge mode, the\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   battery voltage is regulated to 91.57%×VOC, namely 13.55V(Typical). Float charge mode can compensate for\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   the loss of battery power due to self-discharge or external loading.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   Automatic Battery Recharge\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   In float mode, if both the battery and the input power supply (wall adapter) are present, a new charge cycle will\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   begin if the battery voltage drops below 83.95%×VOC due to self-discharge or external loading.\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n   A new charge cycle can also be started manually by plugging off the input supply and reapplying it.\n  \u003c\/div\u003e\n \u003c\/div\u003e\n \u003cdiv style=\"font-size:medium;color:rgb(0, 0, 0)\"\u003e\u003c\/div\u003e\n \u003cdiv style=\"font-size:medium;color:rgb(0, 0, 0)\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv\u003e\n \u003cbr\u003e\n \u003cbr\u003e\n\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Eletechsup Factory store ","offers":[{"title":"with terminal","offer_id":46474140385437,"sku":"DD30CRTA","price":1.99,"currency_code":"USD","in_stock":true},{"title":"no terminal","offer_id":46792303411357,"sku":"DD30CRTA","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/8622\/0189\/files\/HTB1t5NcXvv85uJjSZFxq6yl4XXaD_b97b4c9d-d66d-4eb2-a695-dd42b0560643.webp?v=1738857637","url":"https:\/\/eletechsup.com\/es\/products\/3a-12v-lead-acid-battery-charger-input-15-28v-over-charge-14-8v-float-charge-13-55v-for-ups-car-solar-energy-charging","provider":"Eletechsup Ready Stock Factory Store 6-10days to Worldwide","version":"1.0","type":"link"}
