Test equipment for evaluating the safety of devices connected to a power source against high current and high voltage.
At Showden Co., Ltd., we have introduced a "short-circuit current testing device" aimed at further enhancing the safety of our developed products. This device evaluates the safety of equipment connected to power sources (such as power supply SPDs, power supplies, and distribution boards) against high alternating and direct currents. The device allows for the simulation of short-circuit accidents in alternating current power sources, direct current power sources, and solar power systems through arbitrary adjustments of output voltage and current, and will be utilized in the development of various products. 【Features】 ■ Capable of conducting new JIS (JIS C 5381-11:2014) safety tests ■ The main power circuit can handle high currents, while the auxiliary power circuit can apply high voltages ■ An impulse generator can be combined to apply impulse voltage and current to the sample while it is powered ■ Control over the timing of auxiliary power activation and the timing of impulse application For more details, please refer to the catalog or feel free to contact us.
