Optimum for charge-discharge test of various rechargeable batteries
CD series is an ultra-small design DC charge-discharge power supply that can be easily installed on a test bench. When a battery is connected to the CD series, it safely performs charge and discharge cycle tests while monitoring the battery's voltage, current, and temperature.
With a compact width of 1.38" and 3.31", it can handle up to 108 W charge-discharge. The attached software is very convenient when you conduct multi-channel charge-discharge tests.
As the natural discharge during downtime after charging can be minimized by the suction prevention function, this product is optimum for battery tests.

Functions
Three Charge Modes
Constant Current/Constant Voltage (CC/CV) charge
By setting both the current value and voltage value, the output exceeding the value you set can be disabled.
Constant Current (CC) charge
The charge is carried out at the current value you set. Even if the terminal voltage changes during charge, a constant current can be passed.
Constant Voltage (CV) charge
The charge is carried out at the voltage value you set. Even if the charge current changes, a constant voltage can be applied.
Charge completion condition setting
- Setting of time
- The time can be set up to 999 hours 59 minutes 59 seconds by one-second unit. If the time reaches the setting time, the charge is completed.
- Setting of voltage
- Set the voltage value to complete the charge. If the terminal voltage of the battery reaches the setting value, the charge is completed (only at a constant current charge).
- Setting of current
- Set the current to complete the charge. If the current that is passed to the battery reaches the setting value, the charge is completed (only at a constant voltage charge).
- Setting of -△V
- For some batteries, the voltage increases when the charge is completed, and then the voltage decreases to complete the charge. The voltage reduction value at that time is measured and the charge is completed if the voltage decreases by -△V you set.
Three Discharge Modes
Constant Current (CC) Discharge
The discharge is carried out at the current value you set. Even if the terminal voltage changes during discharge, a constant current can be passed.
Constant Resistance (CR) discharge
The discharge is carried out at the resistance value you set. The value of terminal voltage is measured and the current value for discharge is decided according to the setting value.
Constant Power (CP) Discharge
The discharge is carried out at the power value you set. If the terminal voltage changes during discharge, constant power can be consumed according to the change.
Discharge completion condition setting
- Setting of time
- The time can be set up to 999 hours 59 minutes 59 seconds by one-second unit. If the time reaches the setting time, the charge is completed.
- Setting of voltage
- Set the voltage value to complete the charge. If the terminal voltage of the battery reaches the setting value, the charge is completed.

| OFF | OPEN | VCE 2 V or more |
Sink current 1 mA
* As +S is set to common, input the external control voltage based on +S. Otherwise, a failure may be caused.
Remote sensing
The voltage reduction (VO-VL) due to resistance (R) of the output line and degradation of stability due to contact resistance are prevented (up to 0.5 V).
Various protection functions
For the charge-discharge tests, various protection functions are prepared for protecting your devices and this unit.
- OVP (overvoltage protection)
- OCP (overcurrent protection)
- UVP (under (low) voltage protection)
- OPP (over-power protection)
- OTP (internal over temperature protection 1)
- OHP (internal over temperature protection 2)
- OBP (over battery temperature protection)
- ACF (input voltage reduction)
- RS (remote sense line reverse connection protection)
Battery Temperature Measurement Function
The temperature of a battery is measured by the temperature sensor. If the temperature becomes abnormal, charge and discharge are stopped in an urgent manner to protect the battery.

1. Creating of test condition
Create a condition for charge and discharge.
Up to 16 patterns of charge and discharge sequence can be set. You can set various test conditions according to purpose, such as selecting the charge and discharge mode and setting each protection function.
2. Executing of test
Execute the test for each group you set.
On the execution screen, necessary information such as sequence, thermostatic chamber, the status of power supply, voltage value, and current value at test can be monitored on one screen. If the test is executed for multiple groups at the same time, the statuses can be collectively monitored.
3. Checking of measurement data
Check the completed test data. You can check the data for each cycle of the sequence. You can check the status for each unit time and end condition of each cycle.
The data can be displayed as a graph.
