2.54MM Pitch Signal Power Connector 2.54MM Pitch Signal Power Connector.Chip power connector is used in power module system. It can select the matching power + signal connector according to the need. The feature is that the number of power and signal contacts and the matching sequence can be selected arbitrarily while keeping the connector size and contact core number unchanged. 2.54MM Pitch Signal Power Connector ShenZhen Antenk Electronics Co,Ltd , https://www.antenkconn.com
High-voltage current limiting fuse for transformer protection
                                         -Fuse as per BS standard
This product applies to the indoor AC 50 ~ 60Hz system with the rated voltage of 3.6~40.5kV, and may be used along with other switching devices (such as load switch, vacuum contactor, etc.) This product is as short-circuit and overload protection element for the power transformer and other power equipment. The temperature rise of fuse is slow due to the bus type installation.

Plug (male) / socket (female) can be installed at 90 or 180 degrees. It supports mixed or independent combination of signal and power. The quantity range of power and signal is (2-16) pin and (12-128) pin respectively
Product features
High temperature resistant, glass fiber reinforced and flame retardant polyester is used as insulation material
Copper gold composite conductor with high conductivity is used, and the contact area of the conductor is plated with gold
It adopts shrapnel contact, which has the characteristics of integration, small volume, large current carrying capacity, soft plug-in, blind plug-in, self guidance and high dynamic contact reliability. This series of products can be interchanged with FCI's powerblade series and Tyco's multi-beam series
The length of power hole / signal pin can be selected in two sizes. The power rated current is 45A and the signal rated current is 2.5A
