Power Relays, Over 2 Amps: 7901590000 Application Field and Working Principle

7901590000 power relays are designed for applications with over 2 amps power levels. They are particularly suitable for high-frequency switching operations. By adopting advanced surface mounting technology and high-grade materials, these relays have proven to be reliable, stable, and robust in operation.

The 7901590000 power relays consist of two main parts: the contact assembly and the magnetic latching assembly. The contact assembly consists of an armature, built-in bias (magnetically activated) contacts, an operating coil, and a stationary contact plate. The contact assembly is held in an enclosed housing. When power is applied to the relay, the operating coil creates an electromagnetic field that pulls the armature back, which in turn causes the built in bias contact to close against the stationary contact plate.

The magnetic latching assembly consists of a keep magnet, an operating coil, an electrical switch, an operating magnet, and an indicator light. The keep magnet consists of two poles - the North and South poles - and when the current in the coil passes through the keep magnet, it creates two electromagnetic fields that pull the operating magnet and the electrical switch. When the operating magnet is pulled in one direction, the switch closes against the indicator light. The current in the coil then continues to build up in the keep magnet until it reaches a threshold, triggering the current to flow in the opposite direction. This causes the operating magnet to be pulled in the opposite direction, thus opening the switch, thus deactivating the indicator light.

The 7901590000 power relays provide fast and accurate switching speeds. These relays are also designed for shock and vibration resistance. Additionally, they feature very low power consumption, low on-state resistance, long-term reliability, and excellent temperature and humidity resistance.

In summary, the 7901590000 power relays are reliable, robust, and suitable for high-frequency switching operations, and they provide fast and accurate switching speeds. They feature low power consumption, low on-state resistance, long-term reliability, and excellent temperature and humidity performance.
