DVL serijos įtampos keitikliai

Voltage transducers for Industrial and Traction - for small and medium voltage measurements

Main characteristics:

  • Compact design
  • A unique design to cover all measuring ranges
  • Voltage measurement from 50 to 2000 VRMS
  • High level of insulation test voltage: 8.5 KVRMS / 50 Hz / 1 min
  • High level of RMS voltage (2.7 kV) for partial discharges extinction @10 pC
  • Excellent overall accuracy:
    • +/- 0.4% of Vpn at + 25°C
    • +/- 1% of Vpn over the operating temperature range
  • High bandwidth (short response time): 14 KHz (-3 dB)

Features:

  • DC, AC and pulse voltage measurements with galvanic isolation
  • Power supply: +/- 13,5 ...26,4 V
  • Operating temperature range: -40°C to +85°C
  • Flexibility with modular connections for primary and secondary sides (connectors, shielded cables, terminals ...)
  • Current output as +/- 50 mA or current loop 4 to 20 mA

Standard compliance:

  • EN50155:2007 for traction applications such as:
    • Main and auxiliary converters
    • Circuit breaker
    • Substations
    • Battery chargers
    • Propulsion and braking chopper
    • but also industrial applications
  • European Directive EMC 2004 / 108 / EEC : CE Marking
  • Using UL94-VO recognized materials
  • EN 50121-3-2:2006: Railway EMC standard
  • EN 50124-1:2001: Insulation levels
  • EN 50178:1997: for industrial applications
  • NFF 16101/2: Fire and smoke classification
  • Developed according to IRIS standard

Remarks:

  • New innovative patented insulating digital technology
  • Economic, 30% power saving
  • 30% lighter
  • Unmatched immunity to electromagnetic disturbances
  • Insensitive to magnetic fields
  • 100% compatible with previous generations of transducers in performance and footprint
