Voltage & current accuracy
Accuracy you can audit
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.
Independently verified
Designed and manufactured under an ISO 9001:2015-certified quality system, supported by an ISO/IEC 17025-accredited testing and calibration laboratory.
35 years of instrumentation
Founded 1991. Arbin reinvests 30% of profits into R&D, funding the precision architecture provided with every Arbin test station.
Built for any lab
Scalable channel density in a compact, air-cooled footprint, with open Python and C# API for the automation you already run.
Highlights of the RBT-Module Series
Four hardware decisions that separate the RBT-Module from a conventional high-power cycler.
Regenerative Energy Recovery
up to 90% returned to the grid
Cut the energy cost of pack cycling
SiC-based regenerative circuitry returns discharge energy to the facility grid: up to 90% on the 100 V and 200 V configurations, up to 82% on 30 V through 60 V. Channels share a common DC link, so a discharging channel's energy is reused by a charging channel before anything draws from the mains.
Net facility power draw, and the cooling load needed to remove waste heat, both fall with it.
Parallel Channel Scaling
any number of channels
Raise the current ceiling without a second chassis
Any combination of sequential channels can be connected in parallel to raise the current handling capability for a single test article, rather than choosing from a fixed set of pre-wired banks. Paralleled operation reaches up to 1,200 A per chassis.
Test a higher-current pack with the channels already installed, instead of adding a second system.
Multiple Current Ranges
auto-selecting, every channel
Full accuracy at lower currents
Each channel module is configured with up to three current ranges per channel. The active range switches automatically during a test, including through constant-voltage control, and the rated accuracy and precision follow it.
Low-current diagnostics and full-power cycling run on the same channel, without moving the pack to another system.
Built-In Safety Features
safety monitoring for every channel
Engineered for high-voltage packs
Precharge circuitry matches the DC bus to pack voltage under digital control before the main contactor closes, preventing inrush. Anti-islanding disconnects the regenerative stage within roughly 40 ms if line voltage or frequency leaves its limits.
A channel-level interlock responds in about 20 µs, backed by integrated breakers, fuses, and isolation contactor relays.
Applications and Test Methods
Each channel operates as an independent, digitally controlled charge/discharge source, so one chassis covers module and pack characterization, life-cycle testing, and incoming QC at up to 300 A and 200 V per channel.
Module and small pack life cycle testing
Cycle modules and packs at up to 300 A per channel across a 30 V to 200 V range, with channels paralleled to raise the current ceiling for a single test article. Time-vs-current, time-vs-power, and Rint-model battery simulation profiles run on the same channel.
End-of-line and incoming QC
Capacity, resistance, and voltage verification on incoming or finished packs. Precharge circuitry matches the DC bus to pack voltage before the contactor closes, and every channel enforces its own safety limits.
Drive cycles and BMS validation
Run FUDS, HPPC, DST, and WLTP profiles with set points down to 10 ms, uploaded or streamed over CAN. Rint-model battery simulation supports closed-loop HIL work and BMS validation.
Automated and adaptive testing
Drive the tester from your own software. ArbinCTI over TCP/IP plus Lua scripting support BMS emulation, digital twins, and adaptive fast-charge strategies.

Comparing systems?
Four hardware parameters decide whether test data is suitable to draw a conclusion from. Here is where the RBT-Module lands on each, and the question worth putting to every vendor on your shortlist.
Software and Safety
The two questions a lab asks after the specifications check out: can my team actually drive it, and what happens when a cell misbehaves.
MITS Software
MITS scales from basic charge–discharge cycling to complex protocols with nested conditions. Most tests can be built through the menu-driven interface, while Lua scripting and ArbinCTI are available for advanced automation and external control
- ✓ 30+ programmable control types, 90+ meta variables, and up to 9 nested loops
- ✓Up to 127 reusable sub-schedules, so a validated procedure gets called rather than rebuilt
- ✓Adaptive logging raises acquisition rate during transients and state transitions
- ✓DataWatcher queries the SQL database directly — filter by channel, barcode, or cycle count, overlay up to 9 plots
- ✓PostgreSQL, Microsoft SQL Server, and Apache Kafka streaming
- ✓ArbinCTI TCP/IP API plus Lua scripting for BMS emulation and adaptive control
Safety Architecture
Protection is distributed across channel hardware, an independent controller, and step-level software limits. Critical safeguards remain active independently of the test sequence.
-
- ✓Hardware E-Stop with all-pole disconnection, plus a 2-pin dry-contact trip circuit
- ✓Channel-level safety interlock (~20us) independently disables a faulted channel
- ✓Built-in circuit breakers, protective fuses, and software current/power clamps on every channel.
- ✓Test Object profiles auto-set thresholds from the cell spec and block a test on reverse polarity
- ✓Anti-islanding protection disconnects the regenerative stage within ~40 ms of abnormal grid conditions.
- ✓Behavioral checks flag abnormal rates, voltage excursions, and capacity anomalies
- ✓Tri-color light tower, audible alarms, thermoswitches, variable-speed ventilation
