T&R LU5000 Loading Unit
Includes: Spare fuse set, operating manual. 1 x 5m loading unit power interconnection lead. 1 x 5m loading unit metering interconnection lead. 1 x 2m mains lead.
The PCU2 Mk5 control unit may be used with one of two loading units providing between 5000A or 6000A for 5 minutes or up to 10 or 12kA for short periods. Each loading unit has two outputs which may be connected in series or parallel for maximum flexibility. For example, the LU5000 may be configured to either give a maximum current of 2500A at 8V or 5000A at 4V.
The control and loading units are each housed in tough steel cases fitted with castors and protective lifting handles. The loading units have a small plan area to allow them to be positioned as close as possible to the test object, minimising power requirements and maximising the available current.
Loading Unit Output
The output of the loading unit is continuously variable from zero. Each unit may be operated in series/parallel mode to allow for a greater range of load impedances. All metering and tripping functions are handled by the control unit.
