IsoVu Isolated Probes
-
The IsoVu Measurement Systems can make nearly impossible measurements – like high-side Vgs- a reality, providing today’s power engineer with measurement insights not available in other power systems and instruments. When performing near-impossible measurements, especially in those involving Gallium Nitride (GaN) and Silicon Carbide (SiC), it can be extremely time consuming and cumbersome. IsoVu eliminates those concerns: IsoVu probes offer better common mode rejection and higher bandwidth for high EMI environments and on power FETs like SiC and GaN.

Magnetic Resonance Instruments
-
Integrated Dynamics Engineering
MRI systems represent a significant investment. As magnetic resonance images can be distorted by electromagnetic fields, frequently the location is isolated by passive shielding to somewhat insulate the detectors from image distorting EMI. But for a fraction of the cost of the machine an active EMI compensation can fully protect the image from damaging fields generated by other electrical equipment, passing traffic, elevators or other nearby equipment.

Duct Type Wind Speed Sensor
WSA
-
Due to environmental quality management and energy management, we've developed WSA, wind speed sensors which can be applied on ventilation systems, air conditioning, and negative pressure rooms. WSA is a high-accuracy duct type wind speed sensor which can quickly measure the small wind speed. It is stable, high-accurate, and with small drift only. Also, it can caculate the value of the current air volume depending on the measured cross-sectional area of the ducting. Ducting installation and screwless terminals help the users work more easily. Besides, the sensor is equipped with EMC anti-interference devices so that it can withstand strong electromagnetic interferences.

Inverters
-
Analytic Systems has been producing Pure Sinewave Inverters since 1994. Originally designed for running navigation computers on commercial and fishing vessels, the line has evolved into a range of models with power outputs from 300 to 3600 watts featuring Digital Signal Processor control. High power MosFet technology creates a low voltage Sinewave that is fed into a compact toroidal step-up transformer to produce a very clean low EMI AC output. Northrup Grumman evaluated inverters from all major manufacturers and chose the IPSi series by Analytic Systems for their Army portable command centers for precisely this reason.
