Safety of Unearthed (IT) DC Power Systems
This whitepaper is presented as originally published in 2019, featuring capacitance estimates and other performance data for the Sendyne SIM100 Insulation Monitoring Device. While the specific values and outputs may vary across product families, these safety and electrical design principles and guidelines remain valid for the SIM product family, including the SIM200.

Utilizing Solid State Relays in 3-Phase Heating Control Applications
Three Phase Solid State Relays (SSRs) have been available since shortly after the introduction of Single Phase SSRs in 1970. The first of these relays were nothing more than 3 individual SSRs with a common input connection packaged in a single housing. This basic design concept remains, for the most part, unchanged today.However, even though the function of single phase and three phase relays are quite similar, their applications can vary significantly. This is primarily due to the characteristics of three phase power circuits and the attributes / demands of three phase loads. The proper selection and application of three phase SSRs for Heater control applications depends not only upon a comprehensive understanding of three phase SSRs, but also of the three phase power system and typical loads as well. This paper includes a summary review of three phase power systems, the characteristics of common three phase heating loads, and a comprehensive discussion of three phase SSRs and their application relative to such loads.

Managing Nuisance Tripping in High Inrush Industrial Applications
At their core, circuit breakers are designed to trip when experiencing currents beyond their rated levels. But when managing power protection needs for some applications, high inrush currents create the potential for nuisance tripping if the circuit protection is not properly designed. Read this whitepaper to review which applications may present the largest inrush complications, and how to address the issue.

How Ambient Temperature Affects Hydraulic Magnetic Circuit Breakers and Thermal Breakers
To protect against electrical faults, both hydraulic magnetic circuit breakers and thermal circuit breakers have their place. However, for applications where harsh environments and wide ranges of ambient temperature are possible, magnetic hydraulic circuit breaker delivers advantages in circuit protection that cannot be matched with thermal circuit breakers. Learn more about how ambient temperature affects hydraulic magnetic circuit breakers and thermal breakers in this white paper.

What Design Engineers Need to know about VCA (Voice Coil Actuator) Technology
Voice coil actuators (VCAs) are emerging as an extremely valuable solution for many precision motion applications. As the need for smaller, higher accuracy linear motion control components increases, these actuators are being used in an expanding array of mission-critical equipment from ventilators that help patients breathe, to guiding the arms of asteroid-collecting spacecraft. Originally developed for audio speakers, voice coil actuation technology is now being used to provide precise and reliable motion control for a wide range of medical, industrial process and space applications. Even though it has been around for decades, VCA technology is still a mystery to many design engineers as until recently, the application spaces for which it was a cost-effective solution were relatively restricted. Many designers had to settle for more traditional, but less flexible, solenoid-based devices. Now that powerful MCUs and precise and efficient drivers are readily available, advanced linear motion designs using VCAs are easier and less expensive to implement.

How Integrated Thermal Protection Technology can Prevent Solid State Relay Failure in Industrial Systems
Solid state relays provide robust solutions for electronic switching in load control applications and hold many advantages over electromechanical relays. New, emerging solid state relay designs offer integrated thermal protection that can prevent overheating and improve system safety, efficiency and longevity. What do large industrial/commercial HVAC and refrigeration systems, heavy duty transportation, conveyor belts, assembly lines, medical, energy and other complex manufacturing systems all have in common? Motors. Big and expensive electrical motors that, if they overheat, can be damaged or even destroyed. Most large motor driven machinery requires a system attached to the motor’s power supply that will sense overheating and turn off the motor to prevent this damage. In many cases, this device is an electrical relay that turns power on and off. There are two main types of these relays – electro-mechanical (EMRs) and solid state (SSRs). Download this White Paper to learn more about how integrated thermal protection technology can prevent solid state relay failure.

Utilizing Solid State Relays in AC Motor Control Applications
Solid State Relays (SSRs) and Solid State Contactors (SSCs) are ideally suited for controlling dynamic loads such as motors, particularly where frequent or multiple start/stop cycles are required in an application.  Proper selection of a Solid State Relay/Solid State Contactor to reliably start and stop a motor in each application requires an understanding of the demands placed on the Solid State Control by the motor and application.  Motor Control ratings in Horsepower (HP) or Kilowatt (KW) available on many Sensata | Crydom Solid State Relays and Contactors simplify the selection process, but Solid State Relays with only General Purpose Ratings can also be used to control motors. This following discusses the process that can be followed to select the correct Solid State Relay for motor control in those situations where Horsepower (HP) or Kilowatt (KW) ratings of the Solid State Relay may not be known or available.
