Faith Technology has developed a single-channel programmable DC electronic load FT6300A series, which is widely used in the LED industry test because of its "safe, stable and durable" characteristics.
According to Faith, the FT6300A series electronic load not only provides powerful test functions and friendly human-machine interface, but also is equipped with RS232 interface (with GPIB-RS232, RS485-RS232 option), which is very suitable for LED equipment. Testing can provide a variety of solutions for LED product design and testing.
The FT6300A series electronic load includes various models such as FT6301A, FT6302A, FT633A, FT6304A, FT6305A and FT6306A. Its good stability and careful design, together with the powerful PC software of Faith Technology, said that it is LED equipment. The best choice for testing.
FT6300A series electronic load When testing LED equipment, the main items tested are:
1. Inrush current test. The inrush current is the maximum instantaneous current that is passed before the input current reaches a steady state when the input voltage is turned on or off at a predetermined time interval, and is generally 20A-30A.
2. Overcurrent protection test. It is a load protection function to avoid damage to the LED device and load caused by overload output current including short circuit on the output terminal. The set value of the overcurrent is generally 110% - 130% of the rated current.
3. Overvoltage protection test. It is a function of load protection for excessive voltage between terminals. Generally specified as 130% - 150% of the output voltage.
4. Output undervoltage protection test. When the output voltage is below the standard value, it detects that the output voltage drops or stops the power supply and sends an alarm signal to protect the load and prevent misoperation. It is mostly about 80% - 30% of the output voltage.
5. Overheat protection test. Stop the power supply and issue an alarm signal when an abnormality occurs inside the LED device or when the power supply temperature rise exceeds the standard due to improper use.
6, leakage current test. Leakage current is the current flowing through the ground of the input side. In the LED device, the current is mainly leaked through the bypass capacitor of the squelch filter. Both UL and CSA require that the exposed uncharged metal parts be connected to the earth. The leakage current is measured by connecting a 1.5K ohm resistor between these parts and the ground. The leakage current should be no more than 5 mA. VDE allows: a 1.5KΩ resistor to be connected to a 150nP capacitor. And apply 1.06 times the rated operating voltage. For data processing equipment, the leakage current should be no more than 3.5 mA. It is usually around 1 mA.
7. Insulation resistance test. VDE requirements: There should be a 7MΩ resistor between the input and the low voltage output circuit. Between the accessible metal part and the input, there should be a 2MΩ resistor or 500V DC for 1 minute.
The Fisi FT6300A series electronic load can take corresponding protective measures against the abnormalities (such as over current, over voltage, over power, input reverse connection, overheating and runaway) during the test when testing the LED equipment. Prompt for the corresponding information on the load display.
Faith Technology has equipped the FT6300A series electronic load with powerful PC software. Users can connect the load to the PC through the RS232 port of the Faith electronic load. In addition to the panel operation function (including the steady state test, the PC software is installed. In addition to short-circuit testing, sequence testing, transient testing, automated testing, and OCP testing, it is also possible to observe changes in voltage, current, resistance, and power over time.
