The setpoint monitor provides a scaled output of the current in the inductor. This
output can be used to set the output current amplitude prior to generating an
output pulse.
The indicator LEDs are only to show function and are not tolerance controlled.
The output pulse current may be monitor using the optional external current
monitor board (PCA-9155) via the cable. Scaling is 1000 A/V into 50 Ohms. The
output of this CVR has a 51.1 Ohms resistor in series to provide a 50 Ohm
termination to the coax cable. When properly terminated at the Oscilloscope with
50 Ohms, the monitor will provide an accurate representation of the current
pulses. The shield of the coax is connected to the negative output. The CVR is in
the negative lead.
The output is provided on a high current PCB-mount DSUB connector Amphenol
#77TW-C-8W8-S-MP3V-4R or Connector #3008W8SXX57A30X. A magnet is
mounting on the housing to activate the interlock reed switch.
The driver is provided with a mating output connector Amphenol # 717TW-C-8W8-
P-P3Y or Connector #3008W8PXX51A10X and stripline. Pins 2, 4, 6 & 8 are the
positive pulse output, and pins 1, 3, 5 & 7 are the return.
The +24 VDC input are screw terminals located on the main circuit board.
Connectors E1 and E4 are +24 VDC. E2 and E3 are ground.
