Product Overview

WAYNE KERR 3265B

The Wayne Kerr 3265B DC Bias Unit is used with either the Wayne Kerr 3255B series of Inductance Analyzers or the 3260B Precision Magnetics Analyzer, to evaluate components at currents up to 125A. When one 3265B DC Bias Unit is connected to an instrument up to 25 A of DC bias current can be set in steps of 25 mA with one unit. Additional DC Bias Units can be added such that with five units connected in parallel it is possible to set DC bias currents up to a maximum of 125 A DC. 

Features of the Wayne Kerr 3265B include:

  • Enhances usability of Wayne Kerr Analyzers 
    • 3255B series of Inductance Analyzers 
    • 3260B Precision Magnetics Analyzer 
  • DC Bias Units can deliver between 25 mA and 125 A DC bias current in steps of 25 mA
  • DC Bias Fixture model 1009 allows accurate and safe testing of SMD inductors 
  • Adds additional functionality

Specifications of the Wayne Kerr 3265B include:

Technical specifications 

  • The 3265B series of DC bias units must be used in conjunction with either a 3260B, 3255BL, 3255B or 3255BQ. 

Compliance voltages 

  • Maximum compliance voltage (
  • 10 V compliance at 1 V AC drive level. For f>12 kHz deduct 0.5 V. 

Applications 

  • Permits measurement analysis of wound components with levels of DC bias current higher than the standard 1A 

Variable measured 

  • In impedance mode: L, Z, R, Q, D.
  • Not applicable to Rdc, or transformer measurements 

Measured frequency range 

  • 3255BL 20 Hz to 200 kHz (3265B/5A or 3265B10A only)
  • 3255B: 20 Hz to 500 kHz
  • 3255BQ: 20 Hz to 1 MHz
  • 3260B: 20 Hz to 3 MHz (with 3265BQ/25A) 

Basic accuracy 

  • ± 1%, Varies with measurement speed, frequency and options chosen. 

Measurement terminals 

  • 2-terminals measurement via M8 studs.
  • 4-terminal measurement via Kelvin leads and M8 studs.
  • Measurement terminals internally protected by 1.6A fuses against normal inductor back-EMF or accidental disconnection of inductor.
  • Front panel fuses easily replaced. 

Control connections 

  • I2C bus link controls application of DC current and monitors status of analyzer. Status data includes excessive voltage drop and over temperature 

Optional facilities 

  • 3265B bias units may be connected in parallel to give five times the rated current. 

Interlock 

  • Bias safety interlock socket on rear panel of analyzer provides door lock and closed control lines 

Temperature range 

  • Storage: -40°C to 70°C.
  • Operating: 0°C to 40°C 20 A (3265BQ/25A and 3265B/25A )
  • Full accuracy: 15°C to 30°C (at maximum rated current) 

Power supply 

  • Universal 90 to 255 V AC, 47 to 63 Hz
  • Input current 9 A rms max.
  • Power factor >0.9
  • Unit powers up automatically when connected to a powered analyzer. Isolating switch provided
