The Senographe DMR is a class I type B equipment.
D
Single–phase input voltage:
* 200/208/220/240/380/415 V (± 10 %)
D
50 or 60 Hz (1 Hz)
D
8.5 kVA for exposures up to 4.5 s.
7.5 kVA during 10 s
D
Power factor: 0.61.
D
The maximum line current corresponds to the use of the technique factors 30 kV, Mo
track, large focal spot, and at least 100 mAs.
Line impedance at maximum workload 3.5%.
Line impedances under single–phase installation:
* R = total line resistance (two-wire) of the circuit,
I
* R 380 = line resistance equivalent to R reduced to 380 V (input voltage),
I
* U = local input voltage
R
* typical value: R 380 v 1.2 W at P max = 8.5 kVA.
I
The optional STEREOTIX 2 is supplied through the SENOGRAPHE DMR gantry
(Nominal voltage = 27 V).
D
22 thru 49 kV,
D
20 thru 130 mA.
The generator is always limited by the tube:
