Poor power supply quality—in the form of dips, dropouts, and other voltage variations—can result in electrical malfunctions that can have serious consequences. To verify that automotive systems will ...

Ametek’s EM Test offers the VDS 200Q Series, a four-quadrant voltage drop simulator that can source and sink current using a programmed voltage in both positive and negative polarities. Ametek's EM ...

Q: The left taillight on my pickup is somewhat dimmer than the one on the right side. It’s not bad enough to go through the trouble and expense of having fixed it. But it bugs me. Any chance you have ...

Because of its mass, a battery takes a long time to change temperature. If a vehicle sits out all weekend in a zero-degree environment, it might take 30 hours to warm up the battery. Use the outside ...

The NEC provides a recommendation on voltage drop for branch circuits in Informational Note No. 4 following 210.19(A). A similar recommendation for feeders exists in Informational Note No. 2 following ...

Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines.

The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...
