Ultrafast Rectifiers
-
The ST rectifier diode designs deliver performance for applications with very different VF/Qrr trade-offs depending on targeted functions. The minimal power losses of the ST rectifiers range is totally adapted to mains rectification, bypass, boost, bootstrap, freewheel and HF rectification functions. Inside these generic functions, the topology evolution in e.g. resonance or multilevel is followed constantly by suited designs. Ultrafast rectifiers are belonging to the STPOWER family.

Turns Ratio Testers
TRT Standard Series
-
When it comes to choosing a transformer turns ratio tester, TRT Standard series offers some of the most advanced instruments with LCD display out in the market. Each model measures transformer excitation current and phase shift performs automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. Furthermore, they have a built-in true three-phase power source. Because of that, TRT Standard instruments can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 250 V AC, depending on the chosen model. High test voltage of 250 V AC provides more accurate turns ratio testing compared to other turns ratio testers on the market and extremely low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT Standard series consists of:TRT03 Models (TRT03A, TRT03B, TRT03C) – single-phase voltage up to 100 VTRT3x Models (TRT30A, TRT30B, TRT30C, TRT33A, TRT33B, TRT33C) – single and true three-phase voltage up to 100 VTRT63 Models (TRT63A, TRT63B, TRT63C) – single and true three-phase voltage up to 250 VMore about models differences can be found under the downloads tab, in brochures and comparison sheets.A user can create test templates using the DV Win software and store them in the PC’s memory for later use when in the field.TRT Standard series models have a built-in tap changer control unit. Consequently, it enables remote control of an on-load tap changer (OLTC) directly from the tester. In order to make the most out of this feature, the DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time.

High Voltage EMC Surge Generator
TM510
-
TM510 Surge Generator is mainly used for testing power cable high-resistance and arc-over fault whose grade range is 0-10kV, co-operating with cable fault tester and locating devices to test and locate faults. If the user choose the professional digital milli-ampere-meter, as for cable with grade range about 0- 6kV, the instrument can also be used to do DC&voltage resistance test and current leakage test after the fault is repaired. The instrument is internally equipped with voltage-rise rectifying and discharging device, has complete functions, and is also convenient and safe to be wired and operated.

SparkFun Energy Harvester Breakout
LTC3588
-
This breakout board uses the LTC3588 Piezoelectric Energy Harvester from Linear Technologies. This board can be used not only for harvesting piezoelectric energy, but solar energy as well. There is a bridge rectified input for piezo elements (PZ1 and PZ2) and a direct input (VIN) for DC sources. Both are clamped to 20V. In addition, the board can simply be used as a standalone nanopower buck regulator.
