The STS family includes 3 models: STS 5000, STS 4000 and STS 3000. STS 4000 is not equipped with AC and DC high current outputs. STS 3000 is not equipped: with AC and DC high current outputs, AC and DC high and low voltage outputs. All models can be connected to the Tan Delta module TD 5000 and and to the very high current module BUX 3000.
STS 4000 includes a four-outputs generator: low AC current; low DC current; high AC voltage; low AC voltage.
In the local control mode, the selected output is adjustable and metered on the large, graphic LCD display. With the control knob and the LCD display, it is possible to enter the MENU mode, that allows to set many functions, that make STS 4000 a very powerful testing device, with manual and automatic testing capabilities, and with the possibility to transfer test results to a PC via USB, ETHERNET or Pen Drive. In the PC control mode, the TDMS software allows performing the same tests as in the local mode, with the same control windows. It allows also to download, display and analyse test results obtained in local mode.
TDMS operates with all Windows® versions.
The ease of operation has been the fi rst goal of STS 4000.
This is why the LCD display is so large and the dialogue in MENU mode is made easy. STS 4000 includes three measurement inputs:
- DC voltage (10 V DC).
- AC voltage:
- Current (10 A AC or DC).
– High range (300 V AC)
– Low range (3 V AC)
All these inputs are independent among them and allow the measurement of CT or VT outputs or of another source.
In addition, a digital input (up to 300 V) is available:
it can measure the timing of a wet or dry contact.
The instrument is housed in a transportable aluminium box, which is provided with removable cover and handles for ease of transportation. A transport trolley can also be supplied upon request.
