Description

Hioki AC/DC clamp sensors are best-in-class current sensors for use with power meters, Memory HiCorders and high performance oscilloscopes. The CT6845 is a high-precision 500 A AC/DC current probe that features a wide operating temperature range and large jaw diameter, making them ideal for evaluating the operational integrity of devices that are subject to extreme temperature ranges.

Key Features :

  • Ideal for use in environmental testing with broad -40˚C to 85˚C temperature range
  • High precision with a clamp-type design, ±0.3% amplitude accuracy, ±0.1° phase accuracy
  • Wide-bandwidth from DC to 200 kHz • Single-handed operation and robust locking mechanism
  • Reduced effects from magnetic fields, conductor position, and noise from nearby wires
  • For EV/HEV battery charge and discharge efficiency testing and inverter and power conditioner conversion efficiency evaluations

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year) :

  • Rated current : 500 A AC/DC
  • Max. allowable input : 720 A peak (requires derating)

    • Defined to 200 kHz
  • Output voltage : 4 mV/A (voltage output with the Sensor Unit use with a device having a 1 MΩ input resistance or higher)
  • Core diameter : φ 20 mm (0.79 in)
  • Operating temperature, humidity : -40 °C to +85 °C (-40 °F to 185 °F), 80% RH or less (with no condensation)
  • Power supply : ±11 V to ±15 V DC (Power suppled via the Sensor Unit, which supports 100 to 240 V AC)
  • Power consumption : 7 VA max. (at 500 A/55 Hz, ±12 V power requirement)
  • Dimensions and mass : 153 mm (6.02 in)W × 67 mm (2.64 in)H × 25 mm (0.98 in)D, 400 g (14.1 oz), cord length: 3 m (9.84 ft)
