Choosing the right switch is not only about voltage and current. This guide explains how to select between electrical, pneumatic, contactless, Bluetooth, USB, and pressure/vacuum switching technologies based on the application, operating environment, system interface, safety, and failure behavior.
A military DC-DC converter is only one part of the complete power chain. When MIL-STD-1275F, MIL-STD-704, MIL-STD-461, CS101, and environmental requirements must also be addressed, Input Protection and EMI Filtering can add significant size, weight, and complexity. This article explains how integrating Input Protection, EMI Filtering, and DC-DC Conversion into a single solution can reduce SWaP and simplify system integration.
What is the difference between MIL-STD-1275 and MIL-STD-704, and how do you choose the right power supply? Compare military vehicle and aircraft electrical environments, including 28VDC systems, transients, surges, Power Front Ends, and the key requirements for selecting a military power supply.
Do you really need to measure temperature – or do you simply need to know when it is time to take action?
In many overtemperature protection applications, a Temperature Switch can provide a simpler and more direct solution than a complete temperature measurement system. This article explains the difference between Temperature Sensors and Temperature Switches, how bimetal thermal switches work, when to choose NC or NO, and why installation location, switching temperature, and thermal response are critical to effective protection.
MIL-STD-810 for military power supplies – a guide to Vibration, Shock, extreme temperatures and Conduction Cooling, including mechanical and thermal design, Baseplate considerations, Derating, and the relationship with MIL-STD-1275, MIL-STD-704 and MIL-STD-461.
MIL-STD-461 defines EMI and EMC requirements for military equipment, including CS101 for evaluating susceptibility to disturbances conducted through power leads. This article explains the challenges of designing Input Filters and Power Front Ends, their relationship to MIL-STD-1275 and MIL-STD-704, and how EMC performance can be balanced with size, weight, and efficiency constraints.
MIL-STD-704 defines the electrical power environment for military aircraft. Learn how to select Power Supplies and DC-DC Converters for airborne systems, including transients, surges, voltage dips, power interruptions, Hold-Up requirements, and the relationship between MIL-STD-704, MIL-STD-461, MIL-STD-810, and MIL-STD-1275.
A practical guide to MIL-STD-1275 and the selection of power supplies and DC-DC Converters for military 28VDC vehicle systems. Learn why an 18-36VDC input range alone does not ensure suitability for the MIL-STD-1275 environment, and how to address Transients, Surges, voltage drops, and input protection requirements.
A practical guide to military power supplies and DC-DC converters for defense and aerospace applications. Learn how MIL-STD-1275, MIL-STD-704, MIL-STD-461 and MIL-STD-810 affect power supply design, including surge and transient protection, EMI/EMC filtering, thermal management, SWaP and environmental requirements.
How do you know if a liquid cooling system is really working as designed? From AI Data Centers to Radar, EW and Power Electronics, pressure monitoring can reveal changes inside the cooling circuit before temperature alone tells the full story. Discover how Variohm Pressure Sensors and Combined Pressure + Temperature Transducers can support smarter cooling system monitoring, condition monitoring and system protection.
