FAQ

Q1: Are you trading company or manufacturer ?
We are a manufacturer.

Q2:What can you do if the product is broken?
Our products come with a one-year warranty from the date of acceptance. If any part breaks within this period and cannot be repaired, we will replace it with a new one. Please note that you will need to cover the shipping costs. After the warranty period, we can negotiate solutions and provide lifetime technical support for our equipment.


Q3:Why should we choose your company?
1. Our company is certified with CE, TUV, UL, RoHS, and IATF16949:2016, among others.
2. We offer advanced technical support and maintain a strict quality management system.
3. We provide efficient and timely service through email, WhatsApp, Facebook, and other channels.

Q4:What is the difference between an epoxy contactor and a ceramic contactor?

1. The sealed materials and processes differ: epoxy contactors use epoxy resin and require a baking process, while ceramic contactors use technical ceramics and require laser brazing.

2. The internal filling gases are different: epoxy contactors are filled with nitrogen, whereas ceramic contactors are filled with hydrogen.

3. The return signal function in ceramic contactors is less stable and reliable compared to epoxy contactors.

Q5:Is the whole product series non-polarized?
Yes


Q6: Coil drive mode
