STS-100 static transfer switch(STS)
is a dual-input AC converter switch, and the other way is disconnected, and the one AC input is used to power the load. When the power supply supply is abnormal, STS will automatically switch to the other power supply to ensure that the load is continuously supplied by the other power supply.

FAQ :
Absolutely—our OEM/ODM services include:
- Custom branding: Logo printing, packaging design (we helped a Japanese client create bilingual user manuals);
- Hardware modification: Circuit board adjustments for specific voltage requirements (e.g., 110V vs. 220V);
- Software development: Custom firmware programming (e.g., a smart grid client requested a unique communication protocol).
Lead times for OEM/ODM projects start at 4 weeks, with NDA protection guaranteed.
We launch 2 - 3 new product series annually based on market trends:
- 2024: Released a high - efficiency DC - DC converter series for EV charging stations;
- 2025 Q2: Planning to debut a solar - compatible inverter with MPPT technology.
Subscribers to our newsletter get early access to beta testing (e.g., a Southeast Asian solar installer tested our prototype 3 months ahead of launch).
Standard warranty: 1 - 3 years (depending on product category), covering:
✓ Free repairs for manufacturing defects;
✓ Replacement parts shipped within 48 hours (for urgent cases);
