Latching relay,Shunt,Current transformer
)
The core products are latching relays, shunts and current transformers.
'
Latching relays serve as high?power circuit switches. They adopt weak?electric signals to control the connection and disconnection of high?current main circuits. They can quickly cut off circuits under overload or short?circuit conditions to protect equipment. Meanwhile, they achieve electrical isolation between control circuits and high?voltage circuits to avoid leakage and high?voltage interference. They are widely used in smart meters, new?energy vehicle charging piles, photovoltaic and energy?storage equipment, low?voltage distribution boxes, smart circuit breakers and high?power smart?home control modules.

Shunts rely on stable manganin?alloy resistance to complete precise current sampling. Current passing through the shunt produces a weak?voltage signal, which is analysed by chips to calculate current data and measure power consumption, serving as core metering parts for smart meters. They monitor real?time current and cooperate with relays to cut off power during over?current faults. They apply to smart meters, new?energy charging piles, energy?storage power supplies, photovoltaic inverters, air switches and electric?control equipment for energy metering and current monitoring.

Current transformers convert high?current signals into low?current signals for metering chips to calculate power?consumption data. They isolate high?voltage main circuits from low?voltage control boards to block high?voltage impacts. Real?time current monitoring is supported, and power supply will be disconnected together with relays when overload or short?circuit occurs. They are mainly supplied for smart meters, new?energy charging piles, photovoltaic inverters, energy?storage devices, low?voltage distribution cabinets and power?IoT terminals.
'
Target customers are manufacturers of smart meters, new?energy charging piles, photovoltaic energy?storage products and low?voltage electrical?equipment. The electronic components enable accurate current sampling, circuit switching and over?current protection. They improve metering precision, enhance circuit safety, reduce equipment failure rates and ensure long?term stable operation of terminal electrical devices.
