2.5KV Sealed Automotive Relay Non Contact SPST DC 24V 30 Amp Relay

2.5KV Sealed Automotive Relay Non Contact SPST DC 24V 30 Amp Relay

30A 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 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.

30A Power Relay Features:

1. 2500VAC for dielectric withstand voltage between contact and coil

2. Class F for coil insulation grade

3. Sealed-type or flux-resistance

4. 1 form A/B/C available

5. 900mW or 600mW for option

6. TUV/CQC/UL certification

30A Power Relay Applications:

1. Electric vehicle supply equipment 

2. Automobile field: car electric welding machine

The role of the power relay:

The power relay has the advantages of fast action, stable operation, long service life, and small size. Widely used in power protection, automation, motion, remote control, measurement, and communication devices.

Principle of Power Relay:

A power relay is a device that can produce a jump in one or more electrical output circuits when the input quantity (or excitation quantity) meets certain specified conditions. It can be used in the direct grounding system of the neutral point as a directional element for zero-sequence current protection. The working principle of the power relay is that when a certain voltage or current is applied to both ends of the power relay coil, the magnetic flux generated by the coil passes through the magnetic circuit composed of the iron core, the yoke, the armature and the working air gap of the magnetic circuit. Under the action of the magnetic field, the armature Attract to the pole surface of the iron core, thereby pushing the normally closed contact of the contact to open, and the normally open contact to close; when the voltage or current at both ends of the coil is less than a certain value when the mechanical reaction force is greater than the electromagnetic suction force, the armature returns to the initial state, normally open contact is disconnected and the normally closed contact is connected.
