Adds additional functionality
Component tests up to 125 A DC bias current
To evaluate components at currents up to 125 A the 3265B DC
Bias Units are used with either the Wayne Kerr 3255B series of
Inductance Analyzers or the 3260B Precision Magnetics
Analyzer. When one 3265B/25A or 3265BQ/25A 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.
The 3255BL may only be used with the 3265B/5A and
3265B/10A, 5A and 10A DC bias units. Multiple instruments
may be connected in parallel to give a maximum DC bias
current of up to 50A which may be set in steps of 25 mA.
The instruments have a number of safety and protection
features including a safety interlock system to protect the user
against back EMFs. They are also fully protected against over
temperature, excess voltage drop and sense lead failure.
3265B/25A can deliver up to 25 A in steps of 25 mA
SMD inductor tests up to 50 A
With the addition of the 1009 DC Bias Fixture DC bias
currents up to 50 A can be applied to an SMD inductor
during component test in order to evaluate the devices
thoroughly at the operational bias currents.
The fixture operates with either one or two 3265B DC bias
units and a 3260B Precision Magnetics Analyzer. The
optional 1009 high current lead set will be required if two
3265B/25As are used.
Four front panel mounted BNC connectors and two captive
high current cables ensure simplicity and ease of use with
a 3265B.
Interchangeable component test carriers ensure that the
1009 DC Bias Fixture may be used with a wide variety of
devices. Blank carriers are available which enable device
specific test fixtures to be developed or alternatively a
carrier design and manufacturing service is available.
