Solid State Relays are devices used to switch electrical circuits on or off from remote control, either through manual means (push button) or by using computer automation. The HS103DR-MCPC4890C is a dual-channel type of Solid State Relay (SSR) integrated with two high-active LEDs and a junction field effect transistor (JFET) in a single package. This particular type of SSR is particularly effective in switching circuits on or off in low consumption, demanding situations.

Application field and Working principle

The HS103DR-MCPC4890C is specifically designed for systems where current levels are low but power density and size are a top priority. Typical applications include LED lighting, power adapters/converters, telecommunication equipment, industrial automation and monitoring, scientific instruments, and computer peripheral devices. The HS103DR-MCPC4890C is capable of switching up to 400V in low-current, medium-power applications.

At its core, the HS103DR-MCPC4890C SSR consists of an input or control circuit that is set off when a control signal is sent to it. This control circuit then closes the switching circuit, making the output high (on) and allowing the current to flow, or it can open the switching circuit, making it low (off) and stopping the current. A field effect transistor (FET) is used as the control element in this SSR. It is an efficient device which requires minimal current to operate, ensuring a low standby power consumption.

The output side of the HS103DR-MCPC4890C is made up of two high-active LEDs. This has the advantage of helping to reduce spurious emissions caused by electromagnetic interference (EMI), while providing an integrated, efficient, and safe power output. The LEDs are connected in a parallel circuit so that the output current can be split between the two of them, resulting in longer life times and a higher level of reliability.

The HS103DR-MCPC4890C SSR is designed with a thermal protection mechanism, protecting against overcurrent, overvoltage, and overtemperature conditions. It also has an LED indicator which displays the status of the power on/off cycle. This LED will illuminate to indicate that the output is active and then dim as the output drops.

In conclusion, the HS103DR-MCPC4890C is a dual-channelled, high-duty, ultra-low-power Solid State Relay that is perfect for low-current, high power applications. It has robust protection and integrated LED light output features, making it ideal for LED lighting, power adapter/converter, telecommunication, automation, monitoring, scientific instruments and computer peripheral applications.
