DC electronic load for LED driver Model 63110A and others

DC electronic load for LED driver Model 63110A and others

A DC electronic load that can simulate LED electrical characteristics in a module + mainframe configuration.

The LED driver supplies the energy that serves as the light source for the LED and is designed as a constant current source for the LED. The characteristics of an LED driver differ from those of a typical switching power supply, but the structure is very similar. To evaluate an LED driver, it is possible to perform operational checks using actual LEDs, resistors, and electronic loads with CR/CV modes, but it can be challenging to meet the testing conditions. When evaluating an LED driver with a resistor, the relationship between voltage and current becomes linear, as shown by the blue line, which does not fully utilize the characteristics of the LED. When using a DC electronic load with CR/CV modes, it is desirable for both CR and CV modes to operate stably. However, during LED ON/OFF tests or dimming tests, the protection circuit of the LED driver may cause instability in the operation of the electronic load, posing a risk of not being able to conduct the tests successfully. Using actual LEDs as a load can lead to degradation issues over long-term use and requires significant labor to test various types of LED drivers. Chroma has prepared the 63110A/63113A/63115A, based on the 6310A series, to solve the testing issues for LED drivers.

MPPT Electronic Load Device Series - Operating at Maximum Power Point of Solar Cells

MPPT Electronic Load Device Series - Operating at Maximum Power Point of Solar Cells

Connect to a solar cell and operates at the maximum operating point (Pmax). It can track the maximum power point under various solar illumination, angle, and temperature conditions.

To evaluate the power generation performance of solar cells, it is necessary to actually put the solar cells in a generating state. Without connecting a load, no current will flow, and thus power generation performance cannot be measured. This device consumes the output power by converting it into heat internally when the solar cells are connected. By simply establishing a minimal measurement environment, it is possible to measure the power generation of the solar cells (the device measures voltage, current, and power every second). For tracking the maximum power point, a unique MPPT tracking method is employed, which, in addition to the conventional sequential power comparison (hill climbing method), sweeps the I-V curve output characteristics of the solar cells once per minute to explore the maximum operating point, thereby performing MPPT control. As a result, even when the maximum operating point (Pmax) changes significantly due to sudden weather changes or shading, it continues to track the maximum operating point. Additionally, when combined with a PV analyzer (I-V curve tracer), it is possible to construct a simulated system under load for outdoor exposure tests. This device is used for applications such as confirming domestic power generation amounts for new types of solar cells (perovskite type), vehicle-mounted solar cells, and OEM products.
