FaithTech FT66100A Series Multi-channel DC electronic load

Application field

Production, aging and quality inspection of low-power power supply products such as low-power power supply, DC converter, mobile phone charger, 3C battery, BMS, etc. Automotive wiring harness, connectors, fuses, relays, central electrical box and other product testing; Battery pack, BMS protection board balanced discharge, power tool production testing, LED power board production testing and other related fields.

 Steady-state function

FT66100 series electronic load with constant current, constant voltage, constant resistance and constant power, LED five test modes, can meet a wide range of test requirements. Constant current and constant resistance modes can be used to test whether the output voltage of the voltage source maintains a stable output under different load conditions. For battery chargers and adapters, constant voltage mode can change the output voltage of the charger and adapter to verify that the output current is correct.

Dynamic function

The FT66100 series provides programmable dynamic testing capabilities. The dynamic mode is used to simulate all kinds of on-load sudden changes and anomalies, and is suitable for testing the dynamic characteristics of power supplies. Maximum frequency up to 20kHz, support up slope, down slope, range switching parameter Settings.

OCP test

FT66100 series load itself provides OCP test, mainly used in BMS, power module overcurrent and overpower point test. During OCP testing, the overcurrent protection point of the tested object will be automatically found and recorded in IMAX, PMAX. Combined with the high and low limit values of the test parameters, it can automatically determine whether the test results exceed the set specifications, saving time for product design verification and production line system testing.

Program features

The FT66100 series provides program testing capabilities to simulate complex changes in actual loads. In program mode, the load performs multiple tests on the device based on the file and prompts the test results in the form of Pass or Fail after the test is completed. The advantages of the program mode are especially obvious in the product inspection, which can significantly improve the efficiency of product inspection. The load can store up to 10 programs, each containing 10 sequences, for a total of 100 files. If a single program sequence is not sufficient to test the object under test, you can use the program chain feature to obtain more sequences for testing.

APPLY Mode

The FT66100A series offers a wide range of application modes to suit testing in special situations, including four modes:

Inductive load simulation (CC Rise), capacitive load simulation (CV Rise), constant current constant voltage (CC To CV) and constant resistance To constant voltage mode (CR To CV).

The constant voltage soft start mode is equivalent to a capacitive load, and the size of its analog capacitance is proportional to the rise time of the soft start. The constant current soft start mode is equivalent to an inductive load, and its analog inductance is proportional to the rise time of the soft start. CC TO CV mode and CR TO CV mode are mainly used for battery or capacitor product testing, which can make the discharge more thorough.

SCPI with remote control

The FT66100 series supports standard SCPI commands, through which all functions of panel operations can be implemented. This provides convenience for the establishment of intelligent test platform and the secondary development of users. The FT66100A series can easily achieve remote control of electronic loads through RS232, GPIB (optional), LAN (optional) interfaces.
