DEHNrecord SD klasse A nettanalysator med webserver

Integral, multifunctional measuring equipment based on edge computing with the following functions:

• Supply voltage 230 V, 1-phase via L1, e.g. via busbar directly from surge arrester /no additional wiring or backup fuse required
• Compact housing for simple integration and retrofitting, 5 modules in width / DIN rail mounting
• Voltage quality measurement according to EN 61000-4-30, Class-A-certified
• Permanent transmission of the standardised mean values
• Fault record transmitted in the event of limit value violation / Resulting in significantly reduced data volume for easier handling
• Limit values as per EN 50160 / option of additional definition of individual PQ limit values
• Triggerable transmission of the fault record also without limit value violation / customised triggering via device button or Web-based
• PQ characteristics as per marking concept according to EN 61000-4-30 
• Four-pole load current and power measurement by means of external current coils for measurements of up to either 100 A (split-core current transformer) or up to 1,000 A (Rogowski coils) (cable lengths 3 m)
• Measured value transmission of 5-minute mean values
• Measurement with the correct polarity for detection of reference and regenerative power
• Measurement of temporary / power-frequency overvoltages according to EN50550, including customised parameterisation options; e.g. for reporting low voltage
• Event messages possible via cloud monitor, digital outputs and via email notifications
• Integrated parameterizable I/O interfaces
• 3x inputs, 2x outputs, for event-focussed control commands
• Integrated measurement point concept
• Adaptable by means of busbars directly to surge protective devices
• Communication link via Modbus TCP/IP interface and MQTT protocol (3.1, Azure-based)
• Measured value display either via DEHN Cloudmonitor or via external company-specific cloud platforms / Alternatively by reading from the Modbus register
• GPS location positioning for possible creation of PQ maps
• Web-based device configuration and firmware updates
