Installing the NC-2000 Patient Unit
3.7 Secondary Ultrasound Transmitter
Terminal CN14 is used to connect the Patient Unit to a secondary ultrasound transmitter (see
Figure 20). The second driver transmitter will have the same ID as the Patient Unit and it can
be placed in a separate location from the Patient Unit.

3.8 Power
The Patient Unit requires 24VDC for power. The maximum input current for the Patient Unit is
2.025 A, of which the dome lights are the major contributor. When you are calculating the
power supply current requirements for the Patient Unit, you must add the following together:
1. Patient Unit maximum current: 25 mA
2. The maximum current for your dome lights (check with dome light manufacturer). The
dome light relays are limited to 2.0 A maximum (4 relays x 500 mA per relay).
The sum of 1 and 2 must not exceed 2.025 A and must be less than the maximum current
output of your power supply.
Note:
Do not overtighten the screw terminals.
Notes:
When using the RB-MD-990 power supply to power more than one device,
calculate the total amount of current required for all devices connected—Patient
Units along with their dome lights—so as not to exceed the power output of the
power supply or the power ratings for any connectors.
