A high-performance multifunctional AC power supply ideal for various power environment simulations and IEC standard tests.

The 61500 series is a high-performance AC power supply equipped with the capability to simulate phenomena such as abnormal voltage surges, drops, and short circuits in power line disturbance (PLD) simulations. By utilizing the software, it is possible to conduct international standard tests IEC61000-4-11/4-13/4-14/4-28, and inrush current tests can also be performed through phase control during ON/OFF operations. This power supply can be used in a wide range of fields, from R&D testing based on various standard tests to automated testing systems on production lines.

AC electronic load with optimal power factor and crest factor for three-phase output product applications.

The 63800 series is suitable for testing power devices such as uninterruptible power supplies (UPS), off-grid inverters, AC power sources, switches, and breakers. Even when the voltage waveform is distorted, the 63800 series can simulate load conditions with high peak factors and varying power factors while performing real-time corrections. This capability allows for real-world simulations, yielding reliable and unbiased test results. Additionally, using DSP technology, it can simulate nonlinear rectifier loads through a unique RLC operating mode. In this mode, it detects the DUT's impedance and dynamically adjusts the control bandwidth of the load to ensure system stability. The comprehensive measurement capabilities of the 63800 series allow for monitoring the output characteristics of the DUT. Furthermore, voltage and current signals can be verified on an oscilloscope via analog output. Standard interfaces such as GPIB and RS-232 are used for remote control and measurement data transfer for system integration. Additionally, the built-in digital output can be used to control external relays for short-circuit (crowbar) testing.

A low-cost, compact DC power supply capable of simulating changes in sunlight and time series variations of solar cells, as well as evaluating MPPT characteristics.

One of the most anticipated uses as a next-generation energy source is solar power generation systems. The efficiency of converting the direct current voltage/current generated from solar panels depends on the performance of the power conditioner. However, the power generation efficiency of solar panels is influenced by actual weather conditions, making it difficult to evaluate their performance. To enable testing of power conditioner performance without being affected by real weather conditions, Chroma has provided a DC power supply with a solar array (solar cell) simulation function. This allows for simulation not only of changes in sunlight due to morning, noon, and evening, as well as sunny, cloudy, and rainy conditions, but also of temporal changes. It meets the needs for not only testing the MPPT characteristics of power conditioners but also simulating sunlight variations due to regional differences.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
