Ei Transformer Ensures Consistent Power for Subway Signal Control Systems

Custom special input/output voltage, non-standard installation size, extreme condition (high altitude, heavy salt spray, low temperature) adaptation, as well as integrated 'stabilizer + transformer' all-in-one design to cut extra procurement cost.

We partner with over 100 global authorized third-party certification agencies, to handle compliance testing, certificate of origin and FTA tariff reduction documents, helping customers save up to 30% import tariff in destination countries.

Yes, all our products are equipped with built-in overvoltage, overcurrent, overheating and short-circuit protection modules. It will automatically cut off output when abnormal working conditions occur, effectively protecting connected devices from damage.

Our standard in-stock models cover power ratings from 150W to 10KW, which can meet most application demands from daily civilian use to light industrial scenarios. For special requirements exceeding 10KW, we also accept targeted customized production.
