The CV span runs 0.1-18 V low and 0.1-120 V high with 1 mV\/10 mV resolution, minimum operating voltage is 0.25 V at 24 A or 2.5 V at 240 A, and the 16-bit voltage and current measurement system resolves down to 0.1 mV and 0.1 mA. Transient mode toggles between two load levels at up to 10 kHz in CC mode to exercise a power supply's regulation response.\u003c\/p\u003e\n\u003cp\u003eList mode stores up to seven groups of custom step sequences with 2-84 steps, step widths down to 20 µs, programmable values and slopes, while automatic test mode links up to 100 sequences across modes and load conditions. Remote sensing compensates for lead drops, an analog current monitor BNC feeds an external meter or scope, triggering comes from the front panel, external input, timer or bus, and a built-in battery test mode sets cut-off voltage, capacity level and time. Protection includes OVP\/OCP\/OPP\/OTP plus local and remote reverse voltage (LRV\/RRV), a short-circuit test, adjustable CC slew rate, dual thermostatically controlled fans, and both USB and RS232 interfaces (RS232 on the 8514B) speaking SCPI and legacy 8500-series protocol.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1500 W maximum input power with 0-120 V and 0-240 A input\u003c\/li\u003e\n\u003cli\u003eCC\/CV\/CR\/CW operating modes plus CR-LED mode for LED driver loads\u003c\/li\u003e\n\u003cli\u003eTransient mode up to 10 kHz in CC; adjustable CC slew rate\u003c\/li\u003e\n\u003cli\u003e16-bit measurement system with 0.1 mV \/ 0.1 mA resolution\u003c\/li\u003e\n\u003cli\u003eList mode (7 groups, 2-84 steps, 20 µs minimum width) and 100 automatic test sequences\u003c\/li\u003e\n\u003cli\u003eRemote sense, TTL trigger, current-monitor BNC and analog current control\u003c\/li\u003e\n\u003cli\u003eUSB and RS232 (8514B) interfaces with SCPI and legacy 8500-series protocol\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLoad testing of high-current power supplies and DC-DC converters\u003c\/li\u003e\n\u003cli\u003eBattery discharge characterization with cut-off voltage and capacity limits\u003c\/li\u003e\n\u003cli\u003eLED driver and photovoltaic panel performance verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eB\u0026amp;K Precision 8514B DC Electronic Load Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eInput voltage\u003c\/th\u003e\n\u003ctd\u003e0-120 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInput current\u003c\/th\u003e\n\u003ctd\u003e0-24 A (low) \/ 0-240 A (high)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInput power\u003c\/th\u003e\n\u003ctd\u003e1500 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMinimum operating voltage\u003c\/th\u003e\n\u003ctd\u003e0.25 V at 24 A \/ 2.5 V at 240 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCV mode range\u003c\/th\u003e\n\u003ctd\u003e0.1-18 V (low) \/ 0.1-120 V (high)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCV resolution\u003c\/th\u003e\n\u003ctd\u003e1 mV (low) \/ 10 mV (high)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShort circuit current (CC, typical)\u003c\/th\u003e\n\u003ctd\u003e26.7 A (low) \/ 267 A (high)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTransient operation\u003c\/th\u003e\n\u003ctd\u003eUp to 10 kHz in CC mode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasurement system\u003c\/th\u003e\n\u003ctd\u003e16-bit, up to 0.1 mV \/ 0.1 mA resolution\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eInterfaces\u003c\/th\u003e\n\u003ctd\u003eUSB and RS232 (8514B only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtection\u003c\/th\u003e\n\u003ctd\u003eOVP\/OCP\/OPP\/OTP plus LRV\/RRV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAC input\u003c\/th\u003e\n\u003ctd\u003e110 V \/ 220 VAC ±10%, 50\/60 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eForm factor\u003c\/th\u003e\n\u003ctd\u003e2U, rack-mountable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/www.bkprecision.com\/products\/dc-electronic-loads\/8514B\" target=\"_blank\" rel=\"noopener\"\u003eB\u0026amp;K Precision 8514B product page\u003c\/a\u003e.\u003c\/p\u003e","brand":"B\u0026K Precision","offers":[{"title":"Default Title","offer_id":67777173291195,"sku":"IMM_24542461","price":2377.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/31019.1_01_042022.jpg?v=1792557133","url":"https:\/\/na.indomultimeter.net\/products\/bk-precision-8514b-dc-electronic-load-0-120-v-0-240-a-1500-w","provider":"Indo Multimeter","version":"1.0","type":"link"}
