the setting accuracy and the drift characteristic of constant current (CC) / constant voltage (CV)
generated from the system configuration of the DC power supply and the Electronic load, and it
can apply for the precise evaluation. Any of the adjustment are not required after the system
configuration is set up.
●Precise measurement
The PFX2512 equips the high precision measurement circuit and it detects the battery voltage
and the charge and discharge current in high accuracy. (voltage measurement: 100 µV
resolution and current measurement: 100 µA resolution, and the elapsed time measurement:
within 30 seconds per month (within 10 ppm))
Capable of measuring the amount of power and the integrated capacity even with the pulse
current which is hardly captured.
●Protection functions
The PFX2512 equips the route switch (load switch) which it has a feature of high-speed
interruption function to disconnect immediately between the DUT and the DC power /
Electronic load when the abnormal state are detected.
It detects such as an incomplete connection of the DUT, an abnormality of wirings, the potential
difference when it exceeds a regulated value of the DUT cable and the voltage sensing line, and
it protects connecting equipments and the DUT (battery) from being damaged.
●Equipped with the vibration sensor
In case of disaster, the PFX2512 detects a big shake and the impact when the charge/discharge
test is executed, and it turns off the output. it protects connecting equipments and the DUT
(battery) from being damaged.
For the system requirements, see the BPChecker3000 application software's help file .

General Description
●1000-step pattern charge/discharge feature
You can set up to 1000 CC or CP (with V or I limits) steps.
High-speed charge/discharge switching control enables you to perform complicated charge/
discharge tests with step times as short as 100 ms. The PFX2512 can be used to create a wide
variety of test and simulation patterns for standard tests.
●High-speed charge/discharge switching
Traditionally, it has taken time to switch between controlling power supplies and controlling
electronic loads. This product can be used to control power supplies and electronic loads at the
same time, which enables seamless charge/discharge switching.
●High-speed sampling as fast as 1 sample/ms
Voltage and current can be measured at an interval as short as 1 ms with the specified voltage
or current step as the trigger. You can acquire highly accurate voltage waveforms that are
synchronized with the step current. This is an optimal feature for analyzing DUT impedance and
evaluating service life.
●Expandable measurement feature
By installing a Volt / Thermometer Unit OP02-PFX, you can expand the number of measurement
points by four voltage and four temperature measurement points. There are three option board
slots, so you can expand the number of measurement points by a maximum of 12 voltage and
12 temperature measurement points.

General Description
Selecting the system for the DC power supplies and the electronic loads
The range is different between the charge operation and the discharge operation state. Select the
applicable model of the DC power supply and the Electronic load that meets each requirement.
The following graph indicates the range of allowable charge voltage value / current value
calculated by the formula specified below. Use the equipments which do not exceed the range of
the voltage value (constant voltage value/end voltage value) and the current value (constant
current value).
Maximum charging power = Maximum rated power of the DC power supply －Route loss*1
*1. What is the route loss?
The voltage drop is occurred in the DUT cable, the connecting cable, and the PFX2512 current
passing circuit, etc. caused by flowing the charging current. The route loss is the power loss of the
voltage drop while the execution of charging state. The allowable maximum power in the charging
state is the value subtracting the route loss.
When the charging power exceeds the range of allowable power of the power supply while the
charge operation is executed, the PS / B alarm will be activated and stop the testing.

Applied DC Power Supplies and Electronic Loads
The following graph indicates the range of allowable charge voltage value / current value
calculated by the formula as specified below. Use the equipment that should not exceed the range
of the voltage value (starting discharge voltage value/end voltage value) and the current value
(constant current value). And the discharge voltage should not be applied below the discharge
minimum operating voltage.
When using the constant power discharge function (CP Dish), calculate the value of the discharging
current from the setting value of the constant power and the DUT (battery) voltage, and confirm its
value is within the range of the graph.
Discharge minimum operating voltage*1 =
Minimum operating voltage of the Electronic load + the value of voltage drop caused by the route loss
p. 93 You can perform discharge tests with voltages that are lower than the discharge minimum
operating voltage by using a bias power supply.
*1. What is the discharge minimum operating voltage?
The discharge minimum operating voltage relies on the minimum operating voltage of the
Electronic load. Furthermore, the discharge minimum operating voltage shall be determined with
adding the value of route loss (the voltage drop).
See
When the Electronic load exceeds the allowable power or becomes under the lowest discharge
operating voltage while the discharge operation, the CD / B alarm is occured and abort the test.
