MZC-340-PV
The Sonel MZC-340-PV operates voltages up to 900 V AC with a measurement category CAT IV 1000 V and an efficient ventilation system for smooth and effective operation without downtime. The ventilation system significantly reduces the amount of time required to cool the short-circuit resistor.
The instrument is only controlled by a remote as the energy released at a mains voltage of 800-900 V AC can pose a danger to the personnel performing measurements. That’s why the MZC-340-PV is only wirelessly controlled.
Key Features
- Measurement of very low short circuit loop impedances (with resolution 0.1 mΩ) with a current of 130 A at 230 V; maximum 305 A at 550 V AC and 250 A at 900 V AC.
- Measurements in installations with rated voltages: 220/380 V, 230/400 V, 240/415 V, 290/500 V, 400/690 V, 460/800 V (from 200 V up to 900 V), and frequencies 45...65 Hz.
- Ability to perform measurements in short circuit system: phase-phase, phase-PE, phase-N.
- Differentiation between the phase voltage and the inter-phase voltage while calculating the short circuit current.
- 4p (four-pole) method, test leads do not require calibration (measurement with current up to 305 A).
- Measurement of resistance (RS) and reactance (XS) components
- Remote control.
- Touch voltage and touch shock voltage measurement with resistor 1 kΩ).
- AC voltage measurement in range 0...900 V.
- Frequency measurement 45.0...65.0 Hz.
- Memory of 990 measurement results, data transmission via USB and Wi-Fi.
- Power supply: rechargeable battery.
