CAS - CASR - CKSR

CAS:

Compact Fluxgate based current transducers single supplied (+5V)

3 primary pins


 

CASR:

Compact Fluxgate based current transducers single supplied (+5V) with reference access
3 primary pins

CKSR:

Compact Fluxgate based current transducers single supplied (+5V) with reference access
4 primary pins
Higher creepage and clearance distances

Main characteristics:

 

  • Low offset and gain drift
  • Measuring range up to 3 x IPN
  • Attractive price
  • 12 multi-range models ( 4 models for each type)
  • PCB mounting
  • 5 years warranty
  • Small current measurements from 1.5 to 50 ARMS nominal (6A, 15A, 25A and 50A models)
  • Compact design (30% smaller than LTS - height)
  • Only 2.93 cm2 as PCB mounting area is needed to support the 9g of these transducers
  • High accuracy at +85°C:
    • CAS: 2.5 to 3% of IPN
    • CASR & CKSR: 1.2 to 1.8% of IPN

Features:

  • DC, AC and pulse currents measurements with galvanic isolation
  • Single supply 0, +5 V
  • Isolation test voltage: up to 4.3KVRMS / 50 Hz / 1 min
  • Fluxgate technology
  • Operating temperature range: -40°C to +85°C
  • Voltage output
  • Bandwidth DC to 300 KHz (+/- 3dB), 200KHz (+/- 1dB)
  • Fast response time <0.3µs
  • CASR & CKSR: Reference access on additional pin
  • CKSR: Different primary footprint with 4 pins for higher creepage and clearance distances (8.2 mm) for higher insulation

Standard compliance:

  • EN 50178 for industrial applications such as:
    • Home appliances
    • Solar inverters
    • Servo drives
    • Variable speed drives
    • UPS
    • SMPS
    • Forklift trucks
    • Air-conditioners
    • Current monitoring
    • Welding applications
  • UL 508 (UR marking)
  • Using UL94-VO recognized materials
  • European Directive EMC 89 / 336 / EEC: CE marking
  • Low voltage directive 72 / 23 / EEC
  • IEC 61010-1 safety

Remarks:
  • Each model is multi-range according to primary connection configuration
  • Bipolar currents measurements when single supplied 0/+5V
  • These transducers can directly be connected to the 5V input of µ-controllers and instrumentation cards
  • CASR & CKSR models have an additional pin at the output for more flexibility in applications. This pin provides access to the internal voltage reference which can then be fed to the reference of an A/D converter (Analog Digital) This extra pin can also receive the internal reference (from 0 to 4 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics, allowing cancellation of the reference temperature drift
  • Low influence in common mode
