High-current connector

Outline
 Along with the expansion of green energy such as solar power generation, in order to stabilize current for electric power stations and to respond to the peak cut and shift in offices and HEMS at home for power-saving, the usage of storage battery system to store electricity temporarily is increasing in a proactive manner.
 Recently, the lithium ion type storage battery is increasing for storage systems, so to add to the power supply type, we have proposed a rack and panel type complex connector with a signal contact to check the condition of cell in consideration of the character which every cell has some variation in the amount of accumulation of electricity.
The DW Series connector could reduce manufacturing work time for customers and it is available in four kinds of product lineup including cable type for small-scale storage.

Features
- Conformed to UL approved.
- Electrification countermeasure

Applications
 Storage battery system related equipments, electric power units, PCS (Power conditioner), equipment industries such as semiconductor manufacturing
