AC/DC Auto-Zero Current Sensor CT7742
Product Highlights Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CT7742 is a 2000 A AC/DC Current Sensor that pairs with the detachable Display Unit CM7290 for convenient field testing, while delivering an extended temperature range and auto-zero adjustment to minimize drift due to wide temperature changes that occur during long-term testing. Further extend the functionality of this system by connecting the Display Unit with a Hioki memory recorder or logger. Accurately measure and record even when the temperature changes Ideal for site inspections by using detachable Display Unit Four output formats to output data to loggers or other devices (via Display Unit) WAVE, RMS, PEAK, Hz Rated measurement current: 2000 A AC/DC Max. measurement current: 2000 A (requires derating at frequency) Max. allowable peak input: 2840 A peak Bandwidth: DC to 5 kHz (-3dB) Typical accuracy: ±2.3 deg. (DC < f ≤ 66 Hz) Output rate: 0.1 mV/A Max. rated voltage to earth: AC/DC 600 V (CAT IV) AC/DC 1000 V (CAT III) Core diameter: φ 55 mm (2.17 in) or less Output connectors: HIOKI PL 14 Operating temperature range: -25 °C to 65 °C ( -13 °F to 149 °F ) Dimensions and mass: 64 mm (2.52 in)W × 195 mm (7.68 in)H × 34 mm (1.34 in)D, 510 g (18.0 oz), Cable length 2.5 m (8.20 ft)
