Accurate high-voltage AC and DC electricity readings across the high-energy, photovoltaics and e-mobility sector

Core technologies such as photovoltaics, e-mobility and power supply lines of industrial plant require accurate high-voltage and high-amperage readings. The Voltcraft’s VC-771 PV clamp meter handles the extreme power levels usually found in these sectors.

“The new VC-771 PV is a versatile tester that reads HV AC up to 1500 A, and HV DC up to 2000 A,” explains Harald Lehner who manages Voltcraft products at Conrad Electronic. “Which makes it the perfect choice for really challenging tasks.” 
  
The fact that the clamp meter is able to read 1500A AV, 2000A DC, 1000V AC and 1500V DC opens up a wide range of uses in photovoltaics. This includes uninterrupted measurements of amperages and voltages generated by strings of solar panels. The product  comes with a jaw width of 52mm which allows testing cables with large cross-sections, and A DC zeroing that ensures highly accurate readings. Taking uninterrupted current readings of up to 1500A AC, as generated by electric motors and transformers, is also a very common task in equipment MRO across the manufacturing sector. Moreover, the clamp meter’s selectable low-pass filter is vital if you need to improve the accuracy of readings e.g. taken from frequency inverters used in automation and other industry sectors.       .        
 
Large range of features
 
Measuring high-voltage electricity accurately is not the only strongpoint of the VC-771 PV. The product comes with a comprehensive range of features.

“The clamp meter’s  6000-count LC screen has an auto-backlighting mode that ensures perfect readability in low-light conditions,” explains Lehner. “And electrical engineers will appreciate the Bluetooth function for app-based data logging and the selectable work light next to the jaws. Also part of the package are practical features such as NCV, Data Hold functions, Min/Max readings as well as frequency and temperature testing.”      
  
When it comes to practical hardware features, the VC-771 PV ticks all the boxes, including surge warnings, low battery notifications and auto-switch-off if the product isn’t used for an extended period of time. Moreover, a CAT IV 1000V and a CAT III 1500V rating, IP54 dust- and spray-proofness and a robust design with a rubberised casing ensure both functionality and reliability in adverse conditions.
