Power Relays, Over 2 Amps

JW1FSN-DC48V Application Field and Working Principle

JW1FSN-DC48V is a power relay that is widely used in appliances, electronics, automotive applications and industrial control systems. The relay has a contact rating of 10A at 240VAC and a maximum carrying current capacity of 10A at 48V DC. The coil voltage is a constant DC 48V.

With an almost full load temperature rise of 42K only, which is the temperature difference between the winding and the environment, it has high operational reliability and a wide range of temperature resilience. It is IP40 rated, while working without heat sink in such working environment. Moreover, the creepage and clearance have surpassed basic class requirements, in order to provide improved safety. Its mechanical life is rated at 2 million operations, and its electrical life is rated at 100 thousand operations.

The working principle of the JW1FSN-DC48V relay is based on a magnetic field. When the coil of the relay is energized, the armature and contact point of the relay is pulled up and closed, allowing current to flow from the coil to the contact points of the relay. The magnetic force generated is proportional to the coil current and the distance between the armature and the magnet. When the relay is de-energized, the armature is drawn away from the contact, thereby breaking the circuit.

The JW1FSN-DC48V is built with electro-insulative frame and completely sealed to prevent dust and moisture from entering and to increase life. The insulation strength of this relay is greater than 4KV, so it can be used in a wide range of applications such as security systems, home appliances and industrial controls. Due to its versatile features and durable construction, it is suitable for wide range of environment and can be used in direct and prolonged contact with water or dust.

The JW1FSN-DC48V has an excellent working precision and low power consumption, because fewer components lead to high efficiency and lower temperature rise. Its characteristics are quite stable over a wide temperature range as low as -40℃ and as high as 85℃. The relay have built-in surge protection to protect circuits from damage caused by sudden voltage imbalance and overvoltages.

In conclusion, the JW1FSN-DC48V is a reliable and versatile power relay, with wide application and working temperature range as well as excellent working precision and low power consumption. Its creepage and clearances exceed basic class requirements for enhanced safety; and its electro-insulative frame and dustproof design enable it to be used in a variety of environment.
