Three KINGSINE KA Series Power Amplifiers are deployed in a European laboratory for real-time digital simulation testing applications.

Like our protection relay testers, the KA Series is built on a modular architecture. Core modules are designed as independent plug-in blocks that can be removed and installed individually, just like building blocks.


This design improves performance stability and quality reliability, while making service fast and convenient. Replacement modules can be used immediately without recalibration — a true plug-and-play design.
This plug-and-play modular concept is not limited to one product line — it is a common engineering design approach across the full product portfolio of KINGSINE.
Modular inside — plug and play in practice.
