Pickering Interfaces launched a new family of 110 high-accuracy programmable resistor modules with 2.5W, 5W or 10W power handling capability at 100V or as limited by power. Models 40-251/2/3 target applications that require accurate medium-power programmable resistance such as a programmable load for the testing of Electronic Control Units (ECUs) and fuel level sensing. These ECUs are […]
Extended break-fix support for programmable power supplies
The first phase of the AMECare Reliability Assurance service level agreement (SLA) program is designed to provide “white glove” support for customers’ covered mission-critical power and test devices, with regular preventative maintenance break-fix support and legacy upgrades, beginning with a product’s purchase and extending through its entire lifecycle. The goal of the Reliability Assurance program […]
Programmable ac supplies deliver 0-310 Vac as well as dc
The Preen AFV-P Series of programmable ac power sources with dc output and precision measurement capabilities come in four power levels: 600 VA, 1,250 VA, 2,500 VA, and 5,000 VA, providing clean power with THD less than 0.3% at 50/60 Hz. They deliver a continuously variable output voltage of 0-310 Vac and frequency of 40-500 […]
Low-noise programmable, three-channel supplies designed for high-power circuits testing
The Keithley Series 2230G programmable, low-noise, three-channel power supplies deliver up to 375 W in a compact 2U high, half-rack-wide enclosure. They are designed for accuracy and low noise when testing high power, multi-voltage circuits such as LED drivers, automotive, and power-IC circuits. The power supplies’ three channels are isolated, independent and individually programmable with […]

Pulse generator optimized high impedance capacitive loads
IXYS Corporation announced today the introduction of the PVX-4000-2kV-EX +/- 2000 V Pulse Generator by its IXYS Colorado division. The PVX-4000-2kV-EX is an air-cooled, high voltage pulse generator optimized for high impedance capacitive loads. It is well-suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. Its […]
Better testing with well-controlled ac power
Modern ac power supplies are adept at cleaning up line conditions that can lead to garbled electrical test results. STEVE BOEGLE BEHLMAN ELECTRONICS, INC. IF you plug your product’s power cord into any unregulated standard factory ac main, there is a possibility that the power you are using could corrupt any testing you do. The […]
Safer testing with dynamic power supplies
It can be easier to use programmable auto-ranging power supplies as alternatives to fuel-cell power sources that would otherwise force the installation of safety and compliance equipment just to run a few characterization tests. ERIC TURNER INTEPRO SYSTEMS ONE of the most challenging aspects of configuring a test system is that the test rig must […]
How to use a Megger to measure and test motor insulation
When it comes to checking out electric motors, there are special measuring instruments that may be used to detect and diagnose malfunctions. The insulation resistance tester, generally known by its trade name Megger, is capable of providing critical information regarding the condition of motor insulation. In an industrial facility, the recommended procedure is to perform […]
