Create pulses in combination with the power supply for the evaluation of the power supply and secondary batteries.
The DC electronic load device is optimal for power supply development, evaluating secondary batteries with high-speed variable load settings that are closer to reality, quality control, and for integration into devices that automatically conduct tests. We pursue making the cost, which is part of performance, as easy to use as it has been traditionally, achieving high-speed performance with excellent cost performance. ■80V Model: 3720A (30A/250W), 3721A (40A/400W) ■200V Model: 3722A (20A/200W), 3723A (30A/350W) We also offer a charging and discharging evaluation system for secondary batteries using the 372XA series electronic load devices and DC power supply units. ■Battery Station S

basic information
■Main Features It has four basic load modes: constant current, constant resistance, constant voltage, and constant power, with current available in two ranges (low range and high range), and resistance mode available in three ranges (low range, medium range, and high range). This allows for fine load settings according to load conditions. Additionally, each mode can be combined with a short function. Using a 24-bit A/D converter and a 17-bit D/A converter enables precise settings and provides high feedback resolution. The D/A converter has a conversion rate of 100 kHz, allowing for fast control, and can handle transient settings of up to 50 kHz (10 μs). It can easily perform pulse control when combined with a power supply. The minimum operating voltage is 0.6 VDC at maximum current input.

Company information
T and C Technical has been engaged in the sale of water quality measurement instruments (such as conductivity and resistivity meters) since its establishment in 1988, and has been providing service operations to guarantee their quality for over a quarter of a century. At the beginning of our business, we focused on the quality of ultra-pure water, which is essential for semiconductor manufacturing, and established a method for our representatives to visit customers on-site to perform maintenance, inspection, and calibration of water quality measurement instruments, becoming the first in Japan to do so. In 1993, we began the development and sale of Total Organic Carbon (TOC) analyzers, which are important indicators for ensuring the quality of ultra-pure water. Since then, our TOC analyzers have been utilized by customers in various industries, including semiconductors, pharmaceuticals, food, and beverages. In recent years, we have been engaged in the sale and maintenance inspection of various measurement instruments related to our specialty area of "water," and we aim to contribute to labor-saving and cost reduction in our customers' equipment operations through these efforts. Additionally, we strive to maintain and improve our advanced calibration techniques, ensuring that we provide even greater peace of mind through the maintenance, inspection, and calibration services of the products purchased by our customers.
