Rơ le nguồn Omron G7J

Công ty TNHH Ngân Anh Phát chuyên cung cấp dòng sản phẩm Rơ le nguồn Omron G7J  chính hãng xuất xứ Japan tại thị trường Việt Nam.


Đặc điểm nổi bật của Rơ le nguồn Omron G7J:

  • Bản lề nhỏ gọn cho công suất chuyển mạch tối đa, phù hợp với tải động cơ cũng như tải điện trở và tải cảm.

  • Không xảy ra hiện tượng rung tiếp điểm khi có sụt áp tức thời lên đến 50% điện áp định mức.

  • Chịu được điện áp trên 4 kV giữa các tiếp điểm có cực tính khác nhau và giữa cuộn dây với các tiếp điểm.

  • Sử dụng vật liệu chống cháy (đạt tiêu chuẩn UL94V-0) cho tất cả các vật liệu cách điện.

  • Các mẫu tiêu chuẩn được UL và CSA phê duyệt.

Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with tolerances of +15%/-20%
              for AC rated current and ±15% for DC coil resistance. (The values given for AC rated current apply at 50 Hz or
              60 Hz.)
           2. Performance characteristic data are measured at a coil temperature of 23°C.
           3. The maximum voltage is one that is applicable to the Relay coil at 23°C.

*1. The above values are all initial values.
*2. The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
*3. The operate and the release times were measured with the rated voltage imposed with any contact bounce ignored
       at an ambient temperature of 23°C.
*4. The insulation resistance was measured with a 500-VDC megger applied to the same places as those used for
       checking the dielectric strength.
*5. The electrical endurance was measured at an ambient temperature of 23°C.
*6. This value was measured at a switching frequency of 60 operations per minute.
