Frequency Converter Unit
FCU
-
The Astronics Frequency Converter Unit (FCU) provides frequency conversion of variable frequency aircraft power. Recent trends in aircraft power systems use variable frequency (VF) generators instead of fixed frequency of 400Hz. While the majority of aircraft loads can use VF power, select loads still exclusively require 400Hz and are best addressed by the use of FCUs. The FCU performs the task of converting the power line frequency by leveraging recent advances in solid-state technology to provide dramatic improvements in performance over traditional frequency converter solutions.

IEC Standard Burden Sets (Current)
IEC Burden Sets
-
Testing and calibrating current transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. These burden sets have been carefully designed to meet these requirements. They also provide the standard burdens required for the testing of current transformers for metering service, and for the testing (within the current rating provided by the sets) of current transformers for relaying applications, all as called for by IEC (International Electrotechnical Commission) Publication 185: 1987.

Oil Immersed Transfer Standard
esi SR1030 Series
-
The esi SR1030 transfer standards consist of 12 equal steps. These steps are available in increments of 1 (SR1030-1), 10 (SR1030-10), 100 (SR1030-100), 1k (SR1030-1k), 10k (SR1030-10k) and 100k (SR1030-100k). The esi SR1030 provides four-terminal connections for each step or for series and parallel combinations of these resistance steps using the optional Series-Parallel (SPC102), Parallel Compensation Networks (PC101) and shorting bars (SB103). This improves power dissipation, stability and errors due to variance in temperature. The esi SR1010 and esi SR1030 are used for the same applications and are alike in configuration. The esi SR1030 differs from the esi SR1010 in that it is specially sealed, and values below 100 k are filled with oil to improve changes due to thermal variations.

High Frequency Noise Simulator
SKS-H04GA
-
Shanghai Sanki Electronic Industries Co., Ltd.
The high-frequency noise simulation generator is an EMC test instrument that reproduces high-frequency noise with a fast rise time when the switch is turned on/off. Since the pulse rise time is less than 1ns and contains wide bandwidth noise, it is very suitable for reproducing malfunctions. The line noise entering the power line and the induced noise entering the communication line can be reproduced, and the performance evaluation of the malfunction and function degradation of electronic products can be performed.
