Semco SI 5V 60A 8CH with temperature sensor

1. Product Features:

The constant voltage and constant current charging is safe and smooth, and the voltage and current sampling output of the device is controlled through the four-wire system connection for soft start, so as to make a safe and smooth transition in the constant voltage and constant current charging process to avoid the occurrence of peak damage to the battery.

2. Main Features:

• High-precision calibration: charging current, discharge current, charging voltage and discharge voltage are all calibrated by Agilent with high precision to ensure the accuracy of current and voltage within 5‰.
• Independent channels with configurable parameter and condition setting for each individual channel.
• Equipped with complete input and output devices, hardware and software protection, polarity reverse protection, power failure protection and etc.
• Precise control without overshoot during CC-CV and CV-CC transition.
• Modular design, convenient for maintenance.
• Strong software system and friendly HMI (Human-Machine-Interface).
  • Charge and discharge test, partition capacity and cycle life and other performance tests, software function, friendly human-machine interface.
• Segmental range design, in the operation of the equipment, according to the different output value of the internal intelligent adjustment of the range of the equipment, to ensure the high precision of each stage.
• Excellent thermal performance, unique duct design, through forced air cooling to reduce the impact of high temperature on equipment performance. The dual fan mode is adopted to carry out forced ventilation and cooling for the power cooling module, and the thermal imager is used for thermal simulation tests to ensure that the cooling device works within a reasonable temperature range.
• Channels can be detachable, can be customized according to the needs of each channel in the same box in free parallel, to be compatible with a variety of types of battery test, give full play to the same type of multi- purpose equipment, save equipment costs for customers.
• Multiple conditions (capacity, time, open circuit voltage, discharge platform, ) for battery sorting.
• Automatically calculate the constant current charge ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data.
• The power supply is independent to ensure that the circuit output is even in the process of power supply operation and there is no protection problem.
• Curve analysis and processing: curve analysis function. Can flexibly select the cycle that needs to be displayed, a variety of curve combinations (such as voltage, current, capacity-time; capacity-voltage; cycle times-charge-discharges.

3.   Main Part Functions:

• Modular design for hardware Each channel with more than one module.
• DC-DC conversion mode, with little heat occurring while testing.
• Current sampling device uses imported alloy material, which ensures large current testing ability.
• The current output uses the soft start mode, which avoids heat impact to the battery and the connector caused by the instantaneous output high current ripple.
• Equipment hardware control loop uses current and voltage double loop No ripple for constant current and constant voltage switching.
• The device can measure DC internal resistance and can be used to detect batteries with potential safety hazard or battery with defective connection impedance.
