High-voltage DC relays-NVR6V-200D
This high-voltage Dc Relay launched bySichuan Suchen New Energy Co., Ltd has a rated current of 200A and a maximum switching voltage of 1000VDC. The contacts are made of copper alloy and the contact resistance is below 1mΩ. There are two versions of the coil: 12V and 24V. The holding time is 30ms and the release time is 10ms. The single-channel power consumption is 6W. The load terminal and the coil terminal do not have polarity, making wiring convenient. The total weight of the relay is approximately 250g. The M6 terminal screw is recommended to have a torque of 6-8N·m. A 2-3mm thick copper strip is recommended for use with it.
The overload capacity is the key indicator for distinguishing the grades of high-voltage DC relays. This relay can operate continuously at 200A in an 85℃ environment without any pressure. It can withstand 250A for 2 hours, 300A for 10 minutes, 600A for 2 minutes, and 900A for 20 seconds. The functional temperature limit is 130℃, which is suitable for long-term conditions. It can withstand up to 180℃ for short periods. In terms of electrical lifespan: 10,000 on/off cycles at 450V/200A, and mechanical lifespan of 200,000 times. When the current exceeds 2000A, the external fuse must melt in time; otherwise, the contacts may fail.
The applicable scenarios include the main circuit of new energy vehicle battery packs, energy storage BDU, DC chargers, and photovoltaic combiner boxes, etc. The working temperature ranges from -40℃ to +85℃. For altitudes over 2000m, it should be used with a reduced capacity in accordance with IEC 60947-1. For high-pressure DC relays that have been stored for more than three months, check the oxidation of the contacts before installation, polish them clean, and then use them. The default shipment does not include the connector and wiring harness. It is recommended to use Saki 7283-1020 or Tianhai 0435317.
NVR6V-200D outperforms mainstream competitors in several core indicators such as continuous current carrying, withstand voltage, and electrical lifespan. For small-scale integrators engaged in energy storage packs, DC chargers, and non-road vehicles, it is a worthy alternative option to consider. The product complies with RoHS 2.0.
