guarantees for power conversion and distribution systems.

Core advantages

40A Super Strong Contact Switching Capability
Using high-quality contact materials, precision machining and optimized design ensure that the relay can

maintain stable switching performance under current loads up to 40A, meeting the control requirements of

high-power equipment.
 

6KV surge voltage protection
The unique internal structure design and the application of high voltage resistant materials enable the relay

to withstand surge voltage impacts up to 6KV, effectively preventing equipment damage caused by grid
voltage fluctuations or lightning strikes, and improving the overall stability and safety of the system.
 

UL Insulation Class F Certification

Through rigorous UL testing and obtaining F-level insulation certification, this relay has achieved high
industrystandards in electrical insulation and can operate stably for a long time at higher operating
temperatures, adapting to various harsh working environments.
 

Typical application in new energy EV charging stations
Customized for the new energy industry, particularly suitable for fast charging control of EV charging stations,

ensuringhigh efficiency, safety, and stability during the charging process of electric vehicles, and promoting the

development of green travel.
 

Plastic encapsulation design
Advanced plastic encapsulation technology is adopted, which not only achieves miniaturization and light weight
of relays,but also enhances the product's moisture and dust resistance, improving overall reliability and service
life. The compact packaging form facilitates system integration, saves space, and simplifies installation.

Cautions of New Energy Relay

1.Ordering Information
1.1 The biggest differences between this new energy relay and traditional latching relay or power relay are:
the wider contact distance and stronger dielectric strength of 4000Vac instead of 1500 /2000Vac.
So the contact distance can be 3mm or normal type.
1.2 The nominal voltage of coil are 12Vdc and 24Vdc with the low power consumption of 1.8W or 3W.
Plz note that you should drive the circuit/coil with step-down voltage to ensure power consumption of 1W~1.5W.
1.3 Two poles of contacts of this relay, it means it can control 2 circuits and the default status is 2A-

normally open. Simply put, if you buy it as ev relay then most time the relay is open and not work, some times

they are closed when charging.
1.4 For environment-friendly, you can also choose this relay with lead or without lead (RoHs compliant)
1.5 For more extra request on this relay plz feel free to contact us.

 

2.Application

The typical application of this 40A new energy relay is AC slow charging pile.However if you would to adopt it

into new area, plz don't hesitate to communicate with us at any time.The technical support and before-sales

service are free for you.
