65W industrial PSUs work at 115, 230 and 277Vac

TDK has announced a series of of AC-DC industrial power supplies that can operate on 115V, 230V and 277Vac nominal inputs. Called CSW65 and rated at up to 65W output, the inputs accept 90 to 305Vac, eliminating the need for step down transformers when operating at 277Vac. Operation without forced air cooling is across ambient ...

Kelvin connectors for four-wire measurments

Schützinger’s Kelvin four-wire measurement connectors are now available from JPR Electronics. The connectors allow engineers to measure current and voltage through two opposing measurement channels removing any effects on the measured result due to the resistance of the measuring leads and thermo-voltages. Due to the coaxial arrangement of plug contacts at the instrument end, minimal ...
