Table 2.3: Mod. N1471 Channel technical specifications
Output channels:
Positive or Negative Polarity (requires internal setting, see § 4.1)
Output ranges:
5.5kV / 300µA
Vset / Vmon Resolution:
100 mV
Iset / Imon Resolution:
5 nA
3
Vmax:
0 ÷ 5600 V
Absolute maximum HV level that the channel is allowed to reach, independently from the preset
value Vset. Output voltage cannot exceed the preset value Vmax. The accuracy is 1 % ± 5 V
Vmax resolution:
± 1 V
Alarm output:
Open collector, 100 mA maximum sink current
Interlock input:
LOW: <1V; current~5mA; HIGH: 4÷6 V
Ramp Up/Down:
1÷500 Volt/s, 1 Volt/s step
Trip:
Max. time an "overcurrent" is allowed to last (seconds). A channel in "overcurrent" works as a
current generator; output voltage varies in order to keep the output current lower than the
programmed value. "Overcurrent" lasting more than set value (1 to 9999) causes the channel
to "trip". Output voltage will drop to zero either at the Ramp-down rate or at the fastest
available rate, depending on Power Down setting; in both cases the channel is put in the OFF
state. If trip= INFINITE, "overcurrent" lasts indefinitely.
