Công ty TNHH Ngân Anh Phát chuyên cung cấp dòng sản phẩm Rơ le luân phiên Omron G4Q chính hãng xuất xứ Japan tại thị trường Việt Nam.
Mỗi tiếp điểm trong cơ chế tiếp điểm hai cực thực hiện hoạt động đóng-ngắt xen kẽ tại mỗi xung đầu vào, do đó rất lý tưởng cho việc vận hành xen kẽ hoặc chuyển đổi/chuyển mạch của động cơ.
Hoạt động chính xác được đảm bảo nhờ cơ chế bánh cóc độc đáo.
Đáp ứng khả năng cách điện với điện áp chịu được lên đến 2.000 VAC.
Tiêu thụ năng lượng thấp. (AC: khoảng 6,4 VA; DC: khoảng 3,9 W)

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.
2. The AC coil resistance values are for reference only.
3. Performance characteristic data is measured at a coil temperature of 23°C.
4. The maximum voltage is one that is applicable instantaneously to the Relay coil at an ambient temperature of
23°C and not continuously.
5. The AC power consumption is measured at 60 Hz.

Note: 1. The data shown above are initial values.
2. The contact resistance was measured with 0.1 A at 5 VDC using the voltage drop method.
3. The operate time was 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. The value in parentheses is for
the cased model.
