2.5KV AC Power Relay For EV Charger Station Sealed 30 Amp Relay

Relay Characteristics of Relays

The input signal x of the relay increases continuously from zero to the action value xx when the armature starts to pull in, and the output signal of the relay immediately jumps from y=0 to y=ym, that is, the normally open contact changes from off to on. Once the contact is closed, the input quantity x continues to increase, and the output signal y will no longer change. When the input quantity x drops to xf from a value greater than xx, the relay starts to release and the normally open contact is disconnected. We call this characteristic of the relay characteristic, also called the input-output characteristic of the relay.

AC Power Relay Description:
New energy products, like electric vehicles, must be a trend in the next few days. So more and more fast-charging stations are made and satisfy the need for electric cars power-charging.NB90 series AC relay is specially applied to the charging point. It is a high switching capacity for contacts, is a dust-proof or sealed type option, and is environmentally friendly.

AC Power Relay Features:

1. 4000VAC or 2500VAC is available for dielectric to withstand voltage between contact and coil

2. Class F for coil insulation grade

3. SPDT & SPST

4. Rated current max 40A

5. 900mW

6. TUV/CQC/UL certification

The relay has the following functions:

(1) Expand the control range: For example, when the multi-contact relay control signal reaches a certain value, it can switch, break, and connect multiple circuits at the same time according to the different forms of the contact group.

(2) Amplification: For example, sensitive relays, intermediate relays, etc., can control large power circuits with a very small control amount.

(3) Integrated signal: For example, when multiple control signals are input into the multi-winding relay in the prescribed form, the predetermined control effect is achieved after comparison and synthesis.

(4) Automatic, remote control, monitoring: For example, the relay on the automatic device and other electrical appliances can form a program control circuit to realize automatic operation.
