The flexible current transformers can be placed around one or several conductors of any type and design (insulated cable, busbars, pipes).

Internal batteries allow for an independent operation of the measuring amplifier.

• Wide range of applications, 3 measuring ranges 30 A/300 A/3000 A AC
• and large bandwidth 10 Hz … 20 kHz for harmonic analysis
• Simultaneous measurement in all 3 phases (METRAFLEX 3003)
• Precise measurements even with low currents, due to wide dynamic range and high sensor sensitivity
• Low conductor position influence and minimum stray field influence
• Easy to operate in restricted space thanks to small sensor cross-section of 9.9 mm and slim end cap of 13.6 mm
• Safe handling even with protection gloves; opening of sensor
• and measuring range setting in one-hand operation
• Extremely long battery life of up to 2,000 hours, (METRAFLEX 3003 up to 1,000 hours)
• External power supply for long-term measurements with MAVOWATT 50, connector cable included (METRAFLEX 3001/3003)
• Current sensor with protection type IP65, measuring amplifier with IP40
• High level of safety for the user, measurement category 1000 V@CATIII, 600 V@CATIV and unlimited overload capacity
