EV Charger Sealed DC 12V 50A Relay SPDT 2.5KV PCB Mount NB90-12S-S-C
12V 50A 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.
12V 50A Relay Features:
1. Using brass pins so that it comply with Europe standard
2. 4000VAC for dielectric withstand voltage between contact and coil
3. Sealed-type
4. SPDT & SPST
5. Rated current max 50A
6. 900mW or 1.2W
7. TUV/CQC/UL certification
12V 50A Relay Designation:
1. NB90:Model No. (Max. contact load capacity 50A).
2. A: Contact Form: A: Normally Open B: Normally Close C: SPDT(NO&NC).
3. W: white None: black.
4. 4KV: Between contact and coil dielectric withstand voltage 4KV, None: 2500V.
5. T-105℃: ambient temperature 105℃. None: normal temperature resistant.
6. X: Customer code.
1. Using under a clean environment(excluding H2S, SO2, NO2, and dust contaminants), a dust-proof type is recommended；
Using under polluted environment(containing H2S, SO2, NO2, dust contaminants), a sealed type is recommended, and please contact us during practical application；
2. Avoid using it under strong magnetic or shock extremes conditions, or the technical rating will be changed.
