Ultra Low Voltage DC Electronic Load 63202A-20-1000 / 63202A-20-2000

The Ultra-Low Voltage DC Electronic Load 63202A-20 is available in two models, the 63202A-20-1000 and 63202A-20-2000, and is suitable for the design, test, and verification of voltage conversion modules, point-of-load converters, and embedded DC-DC converters. These voltage conversion modules are critical for providing the proper power supply to central processing units (CPUs) and graphics processing units (GPUs).

The new generation of low voltage high current DC load 63202A-20 introduces a low inductance terminal design, which can reduce the inductance and impedance inside the machine and improve the response speed. The 63202A-20 is especially suitable for low-voltage power supply products under 1.0V. In addition, the output copper row has added a multi-hole locking attachment point to further enhance the ease of use.

The 63202A-20 has excellent low voltage characteristics and can pull load its current rating at low voltages of 0.25V. This makes it ideal for testing DC-DC converters and other products that require low voltage and high current.

These electronic loads offer a variety of basic operating modes, including constant voltage, constant current, constant resistance and constant power modes. In addition, they support User Defined Waveform (UDW) and external signal control functions to simulate realistic current waveforms to meet complex test requirements.

The 63202A-20 can be easily operated through the front panel display and knob, and can be remotely controlled through USB, Ethernet, GPIB and CAN interfaces.

The 63202A-20 introduces three fan control modes, which allow users to choose whether they need noise reduction or fast heat dissipation according to the application environment, and the quiet mode is only 55dB, which is suitable for R&D laboratory environments. The 63202A-20 is also equipped with over-current, over-power, over-temperature protection and over-voltage alarm mechanism, making it a reliable electronic load for product development and testing applications.

In terms of CPU and GPU power supply sequence, most of the 12V or 48V through the DC-DC converter, down to 0.6V to 1.2V for the CPU and GPU power supply, in the DC-DC converter front-end can refer to the Chroma 62000P series, with 40V/120A/1,200W and 80V/60A/2,400W output capacity. Suitable for selection, its DC-DC module output voltage range of about 0.6V to 1.2V, 63202 -20 with 20V, 1,000A or 2,000A, 2,000W with load capacity, especially suitable for low-voltage high-current and other related tests.

The new patented design of low inductance cable, compared to refrigerant cable (inductance 310nH / impedance 8.4mΩ), the new low inductance cable (inductance 105nH / impedance 2.5mΩ) effectively reduces the inductance and impedance and improves the dynamic response caused by inductance under the same length of 60 centimeters. This design also reduces the voltage drop caused by impedance, ensuring stable operation of electronic loads in low-voltage applications.

The 63202A-20 has Constant Voltage, Constant Current, Constant Resistance, and Constant Power modes of operation, which can be used to meet a wide range of test requirements. Constant current is particularly important in the testing of voltage source products, and can be used to confirm that the DUT maintains a stable output voltage under different load conditions; Constant resistance mode is often used in slow power-on testing of voltage sources to confirm the voltage phenomenon of the DUT at the moment of power-on; Constant voltage mode adjusts its output voltage to ensure the accuracy of the current at the set output voltage; Constant power mode is ideal for simulating the pulling behavior of electronic devices. The Constant Power mode is ideal for simulating the pull-load behavior of electronic devices and can accurately perform analysis for other power consumption applications.

In addition to the general fixed-current, fixed-voltage, fixed-resistance, and fixed-power pull-load mode, the traditional way is to send the pre-stored waveforms through the computer to the electronic load through the DAQ card or through the arbitrary waveform generator to achieve the purpose of pulling arbitrary waveforms.

User-defined waveforms are provided in the 63202A-20.^*To simulate the real pulling current, the actual current waveform data captured by the oscilloscope or self-edited current waveforms can be easily stored into the internal memory of the 63202A-20 through the graphical operation software, which can reach up to 1.5 million waveform points, saving the cost of DAQ card and waveform generator. When the DUT needs to simulate more complex waveforms, select the user-defined waveform function, and simply set up through the 63200A's graphical operation software, you can pull and load any waveforms you need.

*User-defined waveform specifications are the same as for the dynamic current load (CCD) mode.
