Chauvin Arnoux MiniFlex® Current Sensor MA110 Series These compact, lightweight and ergonomic sensors of varying diameters are capable of clamping all types of conductors, whatever their number, dimensions or shape (bars, etc.). Due to their flexibility, they can be used in any location, however cramped. They are ideal for the requirements in both industry and the tertiary sector. Their quick and easy opening/closing system makes them simple to handle even when wearing safety gloves.

MiniFlex® MA110 sensors are equipped with an automatic standby function which can be deactivated at start-up for long-term measuring campaigns. They can now be powered in 2 ways: either by batteries or by an external power supply (standard μUSB socket). On the control unit, the 3 LEDs (green, yellow and red) indicate, the battery status, the status of the automatic standby function and any measurement capacity overshoots. The single phase versions offer 4 measurement calibres, while the 3 phase versions offer 3. Comprising 3 flexible sensors which can be connected directly to any multimeter, wattmeter or logger. 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 Features and Benefits • Flexible single phase current sensors • Measurements from 80 mA to 3 kA • MA110 sensors are fitted with Ø 4 mm female banana plugs • 4 calibres • Sensor length (clamping Ø): 17 cm, 25 cm or 35 cm (Ø4.5 cm, Ø7 cm, Ø10 cm) • Ingress protection of sensor/processing unit: IP67 / IP54 • Output signal: AC voltage • Output via two-wire lead terminated by 2 x Ø 4 mm straight male banana safety connectors • Power supply: 2 x 1.5 V AA batteries or external μUSB type B 5 V • Battery life: 300 hours • 600 V CAT IV
