Power Supply Requirements
Electrical Specifications
24V dc Power Supply Use a 24V dc Safety Extra Low Voltage power supply.
Supply Voltage Range: 18V dc to 32V dc
Current Consumption: 300mA at 24V dc
Peak Inrush Current: 5.6 A maximum
Grounding Connect Earth Ground to the Junction Box using the Earth
Ground Screw (shown on page 14).
ATTENTION
!
• The device meets the safety class III in accordance with EN
61131-2 and EN 50178. The 24V power supply for the
equipment must provide appropriate isolation between the
safety-extra-low-voltage circuits and dangerous-contact
voltage circuits (for example, by safety transformers or
similar facilities).
• The power supply circuit must be protected with a 3.15 A
fuse.
• The nominal supply voltage directly of the MobileView
terminal (without the MobileView Connection Cable) is
+24V dc (supply voltage range: 18 to 32V dc).
Typical current consumption is:
- 300 mA at 24V dc
-400 mA at 18V dc
When planning the power supply, take into account the
voltage drop on the Connection Cable.
Specification of power supply lines in this cable:
Cross section: AWG24 (0.24 mm

)
Material: zinc-coated copper strand
Line resistance:
< 90 Ohm/km ( < 145 Ohm/mile)
