8.2.4
Power Requirements
8.2.4.1
Quality of Power
Power quality specifications are based on measurements taken at the nuclear room power
distribution panel.
8.2.4.2
Transient Voltage
> 240 V
None allowed
180-240 V, < 100 µsec
1/day max
90-180 V, < 400 µsec
6/hr, 24/day max
50-90 V, < 800 µsec
6/hr, 24/day max
Table 8.6 Transient voltage tolerances
Note
. If transients on the line exceed specified tolerances, a transient suppressor is recommended
to prevent equipment damage.
8.2.4.3
Voltage Regulation
All combinations of line variation shall not cause the line-to-line or line voltage to deviate from
either its nominal or average value by more than 7 %, whichever is less. For example, assuming a
nominal voltage of 120 V, if the line sags below 111 V or surges above 128 V, an UPS line
conditioner is required. The need for UPS is covered in the section 8.2.4.4.
8.2.4.4
Brownouts
If there are consistent voltage losses exceeding a 30 % drop in peak voltage for more than 5
cycles, a battery uninterrupted power supply (UPS) is recommended. Uninterruptible power
supplies allow at least the case in progress to be completed and should be considered where there
is concern for periodic power loss from any cause (line drop-out, generator testing, etc.) of the
magnitude mentioned. The UPS also has significant benefit in that patient studies are not lost in
the event of power failure or generator test.
8.2.4.5
Source Configuration
The power source supplying CardioMD system shall be single phase, neutral plus dedicated/
isolated ground (3-wire).
Nominal AC Volts
100, 120, 200, 220 or 240
Line Phase
Single
Full Load kVA
1.4 kVA
Line Amps
12 A (100 – 120 V), 6.25 A (200 – 240 V)
Voltage Variation
+10% – 10% from nominal
Table 8.7 Power source configuration
8.2.4.6
Emergency Power
Emergency power is not necessary for CardioMD systems since the procedure being performed at
the time of the power failure would be lost anyway (unless the system is connected to an
uninterruptible power supply). An UPS is strongly suggested for each CardioMD system.
