Arrays

SCRHB125B-8222 is an array type signal transformer collectively referred to as Split Cone Reactor Hybrid Balun (SCRHB) arrays. They are used in power electronics applications for their unique structure. They combine a restricted air gap, arrayed current transformers with a balun to obtain the required current sensitivity through tight coupling.

Signal Transformers

SCRHB125B-8222 signal transformers provide effective signal control and regulation in power electronic applications such as motors, generators, inverters, and other power conversion systems. They can be used to convert input current signals from three phase AC sources to precise, low-noise current signals suitable for power electronic controllers and regulators. They also provide strong isolation and low-leakage between secondaries by employing an advanced air gap structure, an effective solution for challenging, low-voltage to low-voltage scenarios.

Working Principle

The SCRHB125B-8222 signal transformers use an array of current transformers combined with a balun to obtain the required transformation ratio. This combination allows for high-precision and low-noise current monitoring of three phase AC sources. The isolation and low-leakage have been improved through the use of an advanced air gap structure connected to the primary terminals, which also ensures very small losses. The arrayed current transformer units are wound with multiple layers of thin wire and secured together with adhesive tape, forming a compact, light physical structure.

Application Field

The SCRHB125B-8222 signal transformers are a great option in a wide range of applications, including solar energy and wind power generation, automotive electronics, and industrial automation. They are suitable for voltage, current, and power monitoring, providing a safe and reliable environment for these applications. Their small size and weight allow for maximum use in space-constrained locations, such as in electric and hybrid vehicles. Furthermore, SCRHB125B-8222 provides robustness in its immunity to electromagnetic interference (EMI), minimizing potential shock hazards from stray voltage.
