3265B SERIES DC Bias Current Unit

3265B SERIES

specyfikacja

Overview

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. 

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.
