Switching power supplies are compact and efficient
Carlo Gavazzi has extended its portfolio of rail-mounted power supplies with a family of 4 compact housings covering all power and voltage requirements from 7.5 to 100W with 5/12/15/24VDC output
Soft starters deliver more starts per hour
Carlo Gavazzi is introducing a new family of soft starters that combine a built-in bypass contactor with an external heat sink for optimal performance
"The Carlo Gavazzi WM3 meter forms an integral part of the control loop of the test rig, monitoring and recording the motor power requirements for inclusion on the products test certificate," commented Paul Copeman, test development engineer at Rotork.
"Previously the test rig would convert AC voltage, current, frequency and power factors to signal level DC voltage.
These signals were then fed to an analogue-to-digital (A-D) converter for use within the test programme.
The WM3 units provide all the functionality of the previous system at a fraction of the cost and no longer require the PC to be fitted with specialised A - D converters".
Rotork products are shipped to customers worldwide and so need to suit a wide range of power supply requirements, therefore the test rig must supply the unit under test with the appropriate voltage via an automatically controlled variable transformer.
The Carlo Gavazzi unit was chosen over its competitors due to its wide voltage measurement range, up to 690V phase to phase, and good sampling rate, which make it ideal for dynamic tests.
