Transformer Rectifier Assemblies
Transformer rectifier assemblies are very useful in OEM applications when unregulated DC output is required. Input power can be single-phase or three phases. With single-phase input power, the output ripple is 50%. With three-phase input power, the output ripple is 5%. A 5% output ripple is a clear advantage. Hence, transformer rectifier assemblies with three-phase input power are more popular. Circuit breakers, fuses, voltmeters, and ammeters can be added per customer requirements. The assemblies can be an open frame or inside an indoor enclosure.

Regenerative AC load function
61800 Series Optional Function
The regenerative AC load function consists of various modes such as CC Rectified mode, CP Rectified mode, CR mode, CC Phase lead/lag mode and CP Phase lead/ lag mode. The Rectified Mode is capable of simulating non-linear rectified loads with characteristics similar to Chroma 63800 series AC load where the voltage and current operate at the 1st and 3rd quadrant. The Rectified Mode supports both CC and CP functions with current, power and CF as parameter settings.

Thyristors (SCR)
Featuring immunity to surges and transients in static states and commutations, our silicon-controlled rectifiers (SCR), also known as thyristors, are ideal for single- and three-phase power line networks, even in harsh environments up to 150°C. Thyristors (SCR) belong to our STPOWER family.

Field Effect Rectifiers
ST field-effect rectifier diodes (FERD) help improve designs with new versions focusing on trade-off upgrades. Field-effect rectifier diodes belong to our STPOWER family. The design of the FERDs has allowed both a decrease in the voltage drop and a decrease in the leakage current temperature coefficient. As a result, the runaway safety margin is improved and maybe beyond the typical safety margin of Schottky barrier diodes.

Ammeter
AC Rectifier Type Coil Meter
measures the alternating voltage and current with the help of rectifying elements and permanent magnet moving coil type of instruments. However the primary function of rectifier type of instruments work as voltmeter. Now one question must arises in our mind why we use rectifier type of instruments widely in the industrial world though we have various other AC voltmeter like electrodynamometer type instruments, thermocouple type instruments etc? The answer to this question is very simple and is written as follows.
