DR48D12

Solid State Relays (SSRs) are much more reliable than electromechanical relays, and are increasingly the relay of choice where reliability is concerned. DR48D12 is a kind of SSR with high reliability, and today we will take a closer look at its application field and working principle.

DR48D12 has a voltage drop of 2.48V with a resistive load and a wide allowed working voltage between 5 and 30 volts. This makes it suitable for use with an array of different power devices and applications. It can be used in circuit protection, switch control, PLC logic and power control, and even the control of fluorescent lighting.

Typically, SSRs are used in applications requiring high reliability and low voltage control. DR48D12 is no exception, and is especially suitable for use in precision electronic control, medical equipment, laboratory equipment and other related fields.

DR48D12 also have a wide range of operational temperature range, from -40°C to 85°C. This allows them to operate in extreme temperatures while still delivering high performance. Additionally, they have a creepage distance of 7mm and an insulation distance of 3mm, making them suitable for use in sensitive applications.

DR48D12 utilizes a photocoupler, dual thyristor or two gates of MOSFET as its core component. When the input control voltage is applied, DR48D12 will start to conduct and its output voltage will drop. The load is usually limited to 10A at 240VAC, or 30VDC, with a minimum load current of 0.3A.

Moreover, DR48D12 has excellent noise immunity and is resistant to electromagnetic interference. This allows it to be used in applications where interference or noise must be minimized. Additionally, the low voltage control of the DR48D12 gives it a long lifespan compared to electromechanical relays.

In conclusion, DR48D12 is a kind of Solid State Relay that is suitable for a wide variety of applications. It has a wide allowed working voltage, as well as excellent noise immunity and resistance to electromagnetic interference, making it suitable for use in precision electronic control, medical equipment, laboratory equipment and other related fields. Additionally, its long lifespan compared to electromechanical relays makes it an attractive option for applications where reliability is key.
