Transformer

Voltage sensor

This device is a highly stable current sensing power supply for power systems. Its output voltage is DC14V/15V, DC24V. It has battery charging current limiting protection and battery undervoltage shutdown functions. This series of CT power supplies uses direct energy harvesting AC/DC conversion technology, supplemented by power status monitoring and a dedicated energy harvesting current transformer, making the entire CT power supply system small in size and high in conversion efficiency. It meets the requirements of safe power supply under various harsh conditions such as grid large current surges and load switching. It can be widely used in cable and overhead fault indicators.

Leakage current sensor

Hall current sensor

Passive voltage sensor

This source-free voltage sensor converts a measured 0~2000V DC voltage into a 0~+10V DC voltage signal output. The input and output (i.e., primary and secondary sides) are completely isolated, and no additional power supply is required. It features simple wiring, easy installation, small footprint, high accuracy, and high safety. It is especially suitable for high-voltage DC measurement and control in fields such as rail transit, power grids, and industrial automation where power supplies are unavailable.

DC measuring device

This voltage sensor is suitable for the isolated and precise measurement of AC, DC, and pulsating voltages, with complete insulation between the primary and secondary sides during measurement. Main applications include: variable frequency speed control devices, inverters, UPS uninterruptible power supplies, SMPS switching power supplies, electric locomotives, power grid monitoring, etc.

QKSc

Starting reactor

When an AC asynchronous motor starts up under rated voltage, the initial starting current is very large, often many times (generally 5-7 times) the rated current. To reduce the starting current and avoid affecting the power grid, the AC asynchronous motor is usually started by reducing the voltage. Common voltage reduction methods include using reactors or autotransformers. The starting process of the AC motor is very short (generally a few seconds to two minutes). After starting, the reactor or autotransformer used for reduced-voltage starting is removed. This product is designed according to the starting characteristics of high-voltage asynchronous motors and generally matches motor power of 220-1400kW.

isolation transformer

SG series isolation transformers not only have transformer functions in the power grid, but also isolate harmonic interference from the power grid to equipment, protecting machines from heat generation and extending the lifespan of insulation materials. SG and DG series dry-type isolation transformers are widely applicable to various AC 50/60Hz power supply occasions. Various input and output voltages, connection groups, tap positions, winding capacity distribution, secondary winding configuration, and whether a protective chassis enclosure is required can all be designed and manufactured according to user requirements. The external dimensions can be customized according to user requirements.

control transformer

BK series control transformers are suitable for circuits with 50-60Hz voltage up to 500V, typically used as power supplies for machine tool control electrical appliances, local lighting, and indicators. This type of transformer can be divided into shell type according to its structure and vertical type according to its installation method. Dimensions can be customized according to user requirements.
