The BT11 is a High Speed Pulse tester with 1 microcontroller and 1 DC
power supply per channel. It is designed to perform sub-millisecond pulses
on batteries or super capacitors, which are common in wireless or
telecommunication applications.
Model
BT11-5V-5A
Voltage
0V to 5V
BT11-10V-500mA 0 to 10V
Arbin’s pulse capability covers a broad range of sub-millisecond
communication profiles, which can handle multi-stage pulses as fast as
100 microseconds per stage and up to 10 stages per pulse. The pulses
have a maximum length of 2700 seconds.
Power

500mA/50mA/100µA
BT11-10V-100mA -10 to 10V 100mA/50mA/100µA
The BT11 integrates the digital controller and power supply circuitry in a
small footprint as a powerful and completely independent channel. The
channel independence allows users to perform channel calibration while
allowing other channels to continue uninterrupted testing.
Each channel of the system functions as an independent potentiostat/
galvanostat. Commonly used charge/discharge functions such as ramps,
staircases and constant current, voltage, power, and load functions may be
used independently on all channels at the same time. The BT11 allows the
user to run independent pulse and simulation profiles on each channel
simultaneously.
The circuit is a bipolar design that affords tremendous flexibility by ensuring
cross-zero linearity with no switching time. Our MITS Pro Software further
enhances all these capabilities, which according to customer feedback is a
step above all other software in the industry.

Burst mode operation allows user to log data at a very high rate for a maximum time of 500 milliseconds. Up to 300 points per
pulse can be logged across a maximum of 10 stages per single pulse. This application can be useful in instances where fast
data logging is required to catch voltage and/or current data during a transition. By capturing more data, the pulse profile can
be more accurately defined, especially during the charge/discharge transition period (see software screen below). This helps to
identify transition in the charge/discharge process of the objects being tested.

Outputs constant current to the cell or battery at the value specified. Positive current refers to
charge, and negative current refers to discharge.
Outputs constant voltage to the cell or battery at the value specified
C-Rate is common method for indicating the discharge as well as the charge current of a battery.
It can be expressed as I=M*C where I=current A; C=battery capacity; M is the C-rate value
The battery is disconnected from the charge/discharge circuit but remains connected to the
voltage measurement circuit to enable open-circuit voltage measurement
Outputs constant power to the cell of battery at the value specified.

Arbin Instruments provides a wide variety of auxiliary modules for expanding the
capability of the main I, V control circuitry. Each module plugs securely to the bus board.
These auxiliary modules are classified as input, input/output, and control modules.
Input Modules:
Auxiliary inputs can be used to record desired data as well as to
terminate or regulate charge and discharge processes based
upon measured conditions. Selectable inputs are of V
(voltage),
T (temperature), and P (pressure).
Input / Output Modules: Digital I/O is an integrated peripheral on/off control. The output commonly is used to control valves and switches. The input
allows an external control signal to control testing procedure.
Control Modules:
Arbin provides control modules for Auto-Calibration, Smart Battery Testing, External Charger, Temperature Chamber Interface
and AC Impedance Measurement.

Several safety provisions are provided in every Arbin system. There are multiple levels
of fusing provided inside the system for further protection at the channel/board and
power supply levels. The software also has several safety functions with which the user
can avoid over charging the cells, over discharging, overheating, etc.
Smart UPS:
(optional)
This option uses a small Smart UPS to back up power to the computer only.
This allows the system to automatically resume tests after a stop due to
brief power interruption. There is provision for the user to intervene if
desired before the channels resume. This is an essential component for
any user with an unreliable power source unless the entire facility is on
backup power.
