INFORMATION

DESCRIPTION

CVM-NET4+ is a multi-channel power analyzer designed to measure balanced or unbalanced three-phase networks and to measure single-phase networks. Its versatile configuration options enable you to take measurements in single-phase systems, three-phase systems or a combination of both. It has a single three-phase voltage input combined with 12 single-phase channels to measure the current from the MC efficient current transformers.

Its main features include:

• Assembly on DIN rail
• Compact size (6 DIN rail modules)
• Measurement of up to 12 single-phase channels or combined single-phase and three-phase current channels.
• Current measurement using efficient MC series transformers (…/250 mA)
• RS-485 Communications (Modbus/RTU)
• 4 programmable digital outputs for alarms or impulses
• Compatible with PowerStudio /PowerStudio Scada / PowerStudio Scada Deluxe

APPLICATIONS

• Measurement of electrical parameters in multi-channel installations, such as data processing centres and switchboards of single-phase loads.
• Simultaneous measurement at 4 different points in three-phase installations
• Its compact size is perfect for assembly on electric panels.
