AMETEK CTS UCS 200N
Manual for Operation V 2.41 30 / 54
Battery switch
- The battery switch is located on the right part of the equipment and can switch off the battery supply for the DUT.
The time off can be selected. The dc power is switched off during pulse generation of e.g. pulse 1. See the figure
and the table on the previous page.
- When the UCS 200N is powered the battery switch is set into operation. Without being triggered the switch is
closed and the DUT is powered. The red LED on the front panel of the equipment indicates the switching condition.
- The switching off procedure is automatically selected when negative pulses are generated. The range for
switching off time is at 0ms and 0.1ms - 9.9s. The maximum value is limited by the repetition rate. The
synchronisation, switching off and pulse generation, is realized in the control unit.
- For positive pulse generation the operator can select whether the battery supply is switched off or not. The range
for switching off time is from 0.1ms to 9.9s. The maximum value is limited by the repetition rate. If no switching off is
required the pulses are superimposed to the + line.
- The switching off procedure is mandatory for negative pulse generation. Due to decoupling, the low impedance
battery is disconnected and the whole energy is surged to the DUT. For positive pulses the battery is additionally
decoupled by a diode. For negative pulses 0ms also can be selected. The operator shall be aware that most of the
pulsed energy will be absorbed by the low impedance battery. The 0ms setting shall therefore not been selected
for normal test procedures.
- The resolution of the OFF TIME setting is as follows:
- The switch can carry a nominal current of 50A and has a voltage capability of 800V.
- The switch includes a short-circuit protection control unit. The switch is a solid state device.
- The switch is a solid state device.
