MRI POWER SUPPLIES
MRI (Magnetic Resonance Imaging) machines require specific power supplies to operate effectively. MRI power supplies are critical components that ensure the MRI scanner's stability, reliability, and safety. Here are some key aspects of MRI power supplies: Power...
SELENIUM SURGE SUPPRESSORS
A selenium surge suppressor, also known as a selenium surge arrester or selenium surge diverter, was a type of electrical component used in the past for protecting electrical and electronic equipment from voltage spikes and surges in power lines. It was designed to...
SELENIUM RECTIFIER
A selenium rectifier is an early type of semiconductor device used for rectifying alternating current (AC) into direct current (DC). Unlike modern silicon diodes, which are much more efficient and widely used today, selenium rectifiers were made from selenium, a...
SCR, DIODES AND ASSEMBLIES
Certainly! SCR (Silicon Controlled Rectifiers), diodes, and their assemblies are important electronic components used in various applications. Let's explore each of these components and how they can be assembled together: SCR (Silicon Controlled Rectifier): An SCR is...
VARIABLE TRANSFORMER DC POWER SUPPLIES
Variable transformers are primarily designed for use with AC (alternating current) power, not DC (direct current) power. They are not suitable for transforming or controlling DC power. Variable transformers rely on the principles of electromagnetic induction, which...
SCR CONTROLLED DC POWER SUPPLIES
SCR (Silicon Controlled Rectifier) controlled power supplies, also known as SCR power supplies or SCR-based power converters, are electrical devices used to provide controlled and regulated DC power from an AC source. They use SCRs as the main switching components to...
TRANSFORMER RECTIFIER ASSEMBLIES
Transformer rectifier assemblies (TRAs) are essential components in various electrical systems, particularly in applications where a stable direct current (DC) power supply is required. They are commonly used in industries such as aviation, telecommunications,...
BRIDGE RECTIFIERS
A bridge rectifier is an electronic component used in power supply circuits to convert alternating current (AC) into direct current (DC). It's commonly used in various electronic devices and power supplies to ensure a consistent and usable source of DC voltage. Here's...
SCR / DIODE TESTERS
Testing a Silicon Controlled Rectifier (SCR) or a diode requires a few basic tools and methods to ensure they are functioning correctly. Here's how you can test them: Testing a Diode: Turn Off Power: Ensure that the diode is not connected to any power source before...
