Power conditioner evaluation! Solar power generation simulation power source

A solar simulator that reproduces I-V characteristics according to the basic specifications of solar panels, allowing for realistic environmental simulation by setting solar radiation and temperature!

The YRD-SC series is a power supply that simulates the IV curve, which is a fundamental characteristic of solar panels. It can be used to recreate various solar irradiation environments in settings without actual solar panels, allowing for the evaluation of power conditioners and production tests. By linking with the included PC application "Solar Simulation Software," it is possible to simulate a realistic environment that considers changes in solar radiation and temperature from "sunrise" to "sunset," starting from simple IV curve simulations. 【Features】 - Simulates the I-V curve of solar panels (Table Mode, Approximation Mode) - Capable of environmental simulation including solar radiation and module temperature - Time-series simulation from sunrise to sunset - Real-time qualification of IV/PV curves - Data recording (logging) capability - Can be used as a high-precision standalone DC power supply - Safe testing possible with power limiters - Manufactured with necessary specifications ranging from small capacity (3kW) to large capacity (300kW) - Utilizes a newly developed digital power control board, CIC (Common Inverter Controller)

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 deteriorate 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 deterioration. 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
