Here is a quick summary of the article from Design world featuring our SSD Smart Shunt Series.
Riedon Inc., known for its expertise in power and precision resistors, has unveiled the SSD Smart Shunt series, a major product innovation following the success of its SSA Smart Shunt current sensor series. These highly-integrated digital system-in-package (SiP) devices offer plug-and-play simplicity for current measurements, battery voltage monitoring, and coulomb counting in a variety of battery-related current sensing applications. The series includes a 16-bit automotive-grade microcontroller unit (MCU), a 24-bit ADC with buffered analog inputs, and flash memory resources. The new SSD Smart Shunt series provides access to greater data and streamlines integration, building on the accuracy and stability of the original Smart Shunt devices introduced in 2020, which combined the capabilities of passive shunt resistors and Hall Effect current sensors.
Riedon’s SSD Smart Shunt devices boast current sensing capabilities from 100A to 1kA and offer better than ±0.1% full-scale accuracy and linearity. With advanced non-linear temperature compensation mechanisms, these sensors maintain accuracy even in the face of external temperature fluctuations. The devices exhibit exceptional long-term stability, with less than ±0.1% deviation during 1000 hours of operation at 60°C terminal temperature. Operating in a wide temperature range of -40°C to +115°C, the SSD Smart Shunt series is suitable for challenging environments. The compact footprints and low profiles of these sensors make them notably smaller than equivalent current transducers available in the market.
Riedon’s Smart Shunt portfolio, including the new SSD series, is available through distribution partner Digi-Key, providing customers with convenient access to these advanced current sensing solutions. The internal ADC converter simplifies implementation, allowing engineering teams to quickly integrate high-accuracy current measurements into their latest designs or retrofit this function into existing systems. Customers can choose between models with RS485 serial interface or a customizable CANbus interface, meeting diverse application needs. The series comes with various accessories, such as a serial connection kit, pre-made cable and connector, and an isolated base for easy installation and setup.

Following the market traction achieved by its SSA Smart Shunt current sensor series, specialist power and precision resistor manufacturer Riedon Inc. has just announced another major product innovation.
The new SSD Smart Shunt series consists of highly-integrated digital system-in-package (SiP) devices that can be used in a wide variety of battery-related current sensing applications. Each features a 16-bit automotive-grade microcontroller unit (MCU), a 24-bit ADC (with buffered analog Inputs), and a flash memory resource. This brings plug-and-play simplicity to current measurements, battery voltage monitoring, and coulomb counting. Among the places where these devices will be utilized are large-scale energy storage banks, renewable energy generation infrastructure, industrial motor drives, building automation systems, EV charging stations, etc.
The original Smart Shunt devices, which were introduced in mid-2020, brought together the high amperage capabilities of conventional passive shunt resistors and the accuracy of closed-loop Hall Effect current sensors. They present a unique combination of accuracy, stability, and electrical isolation while eliminating the need for periodic calibration work. The new SSD Smart Shunt series now takes this even further – offering access to greater amounts of data, as well as making integration more straightforward.
The internal ADC converter helps to simplify implementation significantly – enabling customer engineering teams to quickly add high-accuracy current measurements into their latest designs or retrofit this function into existing ones. There are two models to choose from. The first is the RS485 serial interface, which can also be configured as MODBUS RTU. The second is a customizable CANbus model.
Riedon’s SSD Digital Smart Shunt devices have current sensing capabilities rated from 100A (2kA peak) to 1kA (20kA peak). They exhibit better than ±0.1% full-scale accuracy, and their full-scale linearity remains within a ±0.1% margin. The advanced non-linear temperature compensation mechanisms these sensors possess ensure that external temperature fluctuations do not affect their accuracy.
Long-term stability is another key attribute of the SSD Smart Shunt series, with less than ±0.1% deviation during 1000 hours of operation (at 60°C terminal temperature). A – 40°C to +115°C (ambient) operational temperature range allows these devices to be used in harsher environments than other current sensing products. The built-in flash memory has an error correction code (ECC) and autocorrects on single-bit errors.
These sensors are housed in packages with footprints of just 68.8mm x 80mm and have extremely low profiles (going down to 16.4mm). They are far smaller than equivalent current transducers on the market for the rated voltages offered.
Accessories for the SSD include: A serial connection kit that facilitates initial sensor setup and enables the CANbus and RS485 interfaces to connect with USB; A pre-made 1 meter cable and connector to allow for ease of installation, without special crimping tools; An isolated base that facilitates mounting;
Riedon’s Smart Shunt portfolio is supplied through its distribution partner Digi-Key.
