Description
The MiniFlex® MA130 is a flexible current sensor comprising 3 measurement loops. It can be connected directly to a power analyser, logger, etc., to measure 3-phase currents or to perform up to 3 independent current measurements.
These flexible coils offer the following major advantages:
• Current measurement even in places where access is difficult
• Large measurement range
• Bandwidth suitable for industrial frequencies and harmonic analysis
• No saturation effect, so no overheating
• Constant low phase shift appropriate for wattmetric measurements
Main specifications:
• Measurement range: 0.5 A to 3 kA
• 3 calibres
• Sensor length (clamping Ø): 25 cm (Ø 7 cm)
• Ingress protection of sensor/processing unit: IP67 / IP54
• Output signal: AC voltage
• Output via 3 coaxial cables terminated by isolated BNC safety plugs
• Power supply: 2 x 1.5V AA batteries or external µUSB type B 5V
• Battery life: 500 hours
• 600 V CAT IV
