Battery step-up/down charging controller 'bq25703A'

Introduction of the synchronous rectification NVDC battery boost/buck charging controller 'bq25703A'.

With a synchronous rectification NVDC battery buck-boost charging controller, it is possible to build a solution with fewer components and high efficiency for charging applications that accommodate various types of batteries while being space-constrained. The NVDC-1 configuration allows the system to be regulated to the battery voltage while maintaining the system above its minimum voltage. The system can continue to operate even if the battery is fully discharged or removed. When the load power exceeds the rated input power, the battery transitions to a supplemental mode to prevent overload of the input power source. Additionally, it charges the battery from a wide range of input power sources, including USB adapters, high-voltage USB PD sources, and traditional adapters. *For more details, please contact us.

Solar Battery Charge Controller TriStar MPPT Series

High voltage module connection available, equipped with MPPT function.

**Features** - High voltage modules for residential industry and others can be connected. It can connect to high output voltage residential industry and thin-film solar cell modules. With the MPPT function, it can charge the battery without wasting the power generated by the solar cells. In standalone solar power systems, it can control up to 3.2 kW. - MPPT Control. The optimal operating point for maximum output of the solar cell array constantly fluctuates due to changes in solar radiation and module temperature. MPPT control follows the optimal operating point of the solar cells that changes according to the situation, ensuring that maximum power from the solar cells is always obtained. - Power loss reduction with maximum efficiency of 99%. Conventional controllers wasted energy due to the large difference between battery voltage and the array's maximum operating voltage. With MPPT technology, it operates at the maximum operating voltage at all times, resulting in almost no power loss. - High durability. The housing is protected from dust and humidity due to epoxy filling and insulation coating. Equipped with protection circuits for overload protection, circuit short-circuit, high voltage protection, over-temperature protection, and nighttime current backflow prevention, it extends the lifespan of the entire system. *For more details, please refer to the catalog download.*

Reproducing energy storage device characteristics! Battery simulation power supply "YRD-BS Series"

It is a battery simulator that can replace actual batteries in the development of vehicle-mounted inverters and other applications.

In tests using conventional real batteries, prior charging of the batteries is necessary. If they degrade due to repeated use, replacement is also required. Additionally, it may be necessary to prepare multiple batteries with different ratings depending on the test subject. For these reasons, there are concerns about decreased reproducibility of tests and increased costs. By introducing this product, more reproducible and stable testing becomes possible. There is no need for charging time, and there are no worries about degradation. Furthermore, it is possible to simulate batteries with various ratings through settings. For these reasons, test time and costs are significantly reduced. 【Features】 - Compact and high efficiency - Various control modes - Achieves fast response - Interfaces support Ethernet and CAN - Local operation uses a touch panel and jog dial - Custom products can also be manufactured
