power transformers are widely used in several fields. Industrial automation: Power transformers are extensively used in industrial production to supply different voltage levels for various electric equipment such as motors and robots. Medical equipment: Medical devices like X-ray machines, magnetic resonance imaging (MRI) system, electrocardiogram (ECG) machines require a stable power supply, and power transformers play a significant role in providing it. Additionally, portable medical devices also use power transformers for charging.

Split-core iron core current transformers are electrical devices used to measure high voltage currents. They can convert high currents into low current outputs and ensure that the current information is not lost during output. This type of transformer consists of an iron core and several coils, with the iron core able to induce current onto the coils which is then stepped down through the circuit.

A current clamp mainly consists of a jaw, a circuit board, a digital display screen, and operating buttons. The jaw is the core component of the current clamp, typically made of ferromagnetic materials with a pair of electromagnets inside to detect current signals and convert them into voltage signals. The digital display screen is used to display the measured current value, and the operating buttons are used to set parameters and switch between function modes.

The cage-style terminal consists of three parts: the terminal, the connecting piece, and the spring piece. After riveting the terminal and the connecting piece together, the spring piece is attached to the connecting piece.

Cage-style terminals are primarily suitable for breeding, experimentation, breeding, and research work involving animals, insects, and other organisms that require centralized and enclosed management and have a certain range of activity in the fields of industry, agriculture, breeding, and scientific research.

Brass terminals are commonly used connectors in electronic components, widely applied in various electronic devices.

The first-ever InnoEX, along with the Hong Kong Electronics Fair (Spring Edition) has opened at the Hong Kong Convention and Exhibition Centre at 12-15/04/2023, attracting a large number of professional visitors to stop, consult and experience.

A measurement method for parallel resistance of solar cells 1. The larger the series resistance is, the more the short circuit current drops, and the more the filling factor will accordingly; The smaller the shunt resistance, the greater the current, the more the open circuit voltage drops, and the more the fill factor drops.

Motor test measurements usually require ammeters to be equipped with multiple shunt units to solve the problem of ensuring the desired measurement accuracy over a larger measurement range. At this point, the rated voltage drop of all shunt used must match that of the ammeter (e.g. 75 mV).
