Expansion of A2L-Driven Systems Shows Continued Growth of Solution
The industry-wide migration toward A2L refrigerants - driven by evolving environmental regulations – has made a wide variety of impacts across the global HVAC industry. Verticals outside of traditional building cooling – such as commercial and transport refrigeration and data center cooling - are about to shift to A2L frameworks. And those shifts toward A2L have also introduced new thermal and safety considerations into HVAC/R system design.

Leveraging Voice Coil Actuators in Fast-Steering Mirror Applications
Fast-steering mirrors (FSMs) have tremendous utility in a variety of sectors, including astronomy, laser communication, and military/defense applications. Motion control is a critical function of these assemblies, with accurate positioning requirements and critical needs for responsiveness and limited or no cogging. Available in a variety of design configurations, voice coil actuators provide the precise, reliable motor control needed – with smooth acceleration and almost zero hysteresis. The limit for accuracy in the system is governed only by the position sensor designed into it.

Insulation Monitoring of DC Charging Stations
Proliferation of quick charging stations is essential for the wide spread adoption of e-mobility. Interoperability of charging stations and EV/PHEVs is promoted through industry associations like CHAdeMO and CharIn. As Electric Vehicle Supply Equipment (EVSE) requirements move to higher DC voltages in order to accommodate heavier vehicles, safety of EVSEs is elevated as one of the first priorities for the industry. An Isolation Monitoring Device (IMD) is the device assigned with the task of monitoring for potential electrical hazards each EVSE. In this paper we will present the international standards requirements for this safety monitoring function and we will discuss the effectiveness of technologies in fulfilling these requirements.

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.
