\n\t\t\tAccuracy you can audit\t<\/h6>\n\t

Accuracy and precision are published as two separate numbers, never blended into one, so you can verify the spec yourself instead of taking a vendor’s word for it.<\/p>\n

\n\t\t\tIndependently verified\t<\/h6>\n\t

Designed and manufactured under an ISO 9001:2015-certified quality system, supported by an ISO\/IEC 17025-accredited testing and calibration laboratory.<\/p>\n

\n\t\t\t35 years of instrumentation\t<\/h6>\n\t

Founded 1991. Arbin reinvests 30% of profits into R&D, funding the precision architecture provided with every Arbin test station.<\/p>\n

\n\t\t\tBuilt for any lab\t<\/h6>\n\t

Scalable channel density in a compact, air-cooled footprint, with open Python and C# API for the automation you already run.<\/p>\n

\n\t\t\tHighlights of the RBT-Cell Series\t<\/h2>\n\t

Four hardware decisions that separate the RBT-Cell from a conventional high-current cycler.<\/p>\n

\n\t\t\tRegenerative Energy Recovery\t<\/h2>\n\t

up to 83% returned to the grid<\/p>\n

\n\t\t\tCut the energy cost of every cycle\t<\/h2>\n\t

SiC power stages return up to 83% of discharge energy to the facility grid. Channels share a common DC link within each module, so energy leaving a discharging channel is reused directly by a charging channel before anything is drawn from the mains, cutting the energy cost, and the HVAC load, of every cycle.<\/p>\n

\n\t\t\tMarket Leading Specifications\t<\/h2>\n\t

100 ppm precision, 24-bit resolution<\/p>\n

\n\t\t\tSee cell behavior – not tester uncertainty\t<\/h2>\n\t

Voltage and current measurement precision reaches 100 ppm (\u00b10.01% FSR)<\/strong>, with \u00b10.01% FSR current accuracy and \u00b10.015% FSR voltage accuracy. 24-bit resolution provides fine control and measurement granularity across each current range, taken through 4-wire Kelvin connections.<\/p>\n

Subtle shifts in resistance, voltage response, and coulombic efficiency stay visible and repeatable even at full current.<\/p>\n

\n\t\t\tFlexible Channel Paralleling\t<\/h2>\n\t

any number of channels<\/p>\n

\n\t\t\tGroup channels for more current\t<\/h2>\n\t

Any combination of channels on a module can be connected in parallel to raise the current ceiling for a single test article, rather than choosing from a fixed set of pre-wired banks. Paralleled operation reaches up to 1,600 A<\/strong> per module.<\/p>\n

Test a higher-current cell with the channels you already have, without a second system.<\/p>\n

\n\t\t\tBuilt-In Safety Features\t<\/h2>\n\t

safety monitoring for every channel<\/p>\n

\n\t\t\tIndependent monitoring, separate from control\t<\/h2>\n\t

Each channel module runs a dedicated microcontroller for precise control plus a second, redundant microcontroller that watches voltage safety limits on its own. Protective fuses sit on the IV channel boards, and thermoswitches with variable-speed fans hold the cabinet inside thermal limits.<\/p>\n

Device profiles set safety thresholds automatically and block a test from starting if reverse polarity is detected.<\/p>\n

\n\t\t\tApplications and Test Methods\t<\/h1>\n\t

Up to 400 A per channel and 1,600 A paralleled, with regenerative circuitry that returns discharge energy to the grid across long high-current programs.<\/p>\n

\n\t\t\t\t\"app\n\t<\/figure>\n
\n\t\t\tHigh-current life cycle testing\t<\/h5>\n\t

Cycle large-format cells at up to 400 A per channel for months at a time. Regenerative circuitry returns up to 83% of discharge energy back to the system and the grid.<\/p>\n

\n\t\t\t\t\"02\n\t<\/figure>\n
\n\t\t\tIncoming QC and cell grading\t<\/h5>\n\t

Grade and sort incoming cells against your own pass criteria at production current. Up to 64 channels per chassis, each running its own schedule and safety limits.<\/p>\n

\n\t\t\t\t\"rbt\n\t<\/figure>\n
\n\t\t\tFast-charge and drive-cycle simulation\t<\/h5>\n\t

Upload drive cycles and duty profiles as time vs. current, power, or load with set points down to 10 ms. Lookup tables adjust the output against measured voltage, temperature, and state of charge.<\/p>\n

\n\t\t\t\t\"04\n\t<\/figure>\n
\n\t\t\tAutomated and adaptive testing\t<\/h5>\n\t

Drive the tester from your own software. ArbinCTI over TCP\/IP plus Lua scripting support BMS emulation, digital twins, and adaptive fast-charge strategies.<\/p>\n

        Four hardware parameters decide whether test data is suitable to draw a conclusion from. Here is where the RBT-Cell lands on each, and the question worth putting to every vendor on your shortlist.<\/p>\n\t
