JORDUN provides full process technical support from product selection to failure analysis

The electrical environment of different application devices is different, and the same protective device cannot cover all applications. The truly effective protection scheme should start from the customer's circuit conditions and failure modes.

JORDUN targets customers in photovoltaic inverters, energy storage PCS, automotive OBC, AI server power supplies, RRU base stations, and industrial power supplies, establishing sales channels FAE、 A technical service mechanism that involves collaborative participation between research and quality.

Customers only need to provide application equipment, input voltage, system power, surge level, installation location, existing protection solutions, and encountered problems, and the Qiaoton technical team can assist in analyzing protection nodes and potential failure risks.

The service content includes product selection, circuit scheme evaluation, sample application, testing condition recommendation, abnormal sample analysis, and customized specification development. For key projects, continuous tracking can be conducted based on customer verification progress to assist in resolving issues that arise during testing and import processes.

JORDUN hopes to provide customers with not just a product model, but a set of circuit protection solutions that can be validated, mass-produced, and continuously optimized.

  • Photovoltaic inverter protection is moving from single point protection to system collaboration

    With the development of photovoltaic systems towards high voltage, high power, and long-term outdoor operation, a single MOV is no longer able to cover all abnormal operating conditions. Lightning surges, power grid fluctuations, abnormal power frequency overvoltage, device aging, and high-temperature operation may all affect the long-term reliability of inverters.

  • Energy storage PCS imposes higher reliability requirements on protective devices

    Energy storage PCS have the characteristics of bidirectional power flow, frequent charging and discharging, long operating time, and high fault energy. Its protection design not only needs to consider external lightning surges, but also issues such as grid anomalies, battery side fluctuations, pre charge shocks, switch transients, and sustained temperature rise. For energy storage systems, it is recommended to configure surge protection, overheating disengagement, surge current limitation, interface transient protection, and temperature monitoring devices according to different nodes, forming a graded and monitored system protection architecture.
