Product Usage Instructions
Installation of 12 VDC Remote Power Supply
To install the 12 VDC remote power supply, follow these steps:
- Ensure that the power is disconnected before opening the supply enclosure.
- Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working with circuit boards.
- Refer to the iQUBE2 Installation Manual, PN 106113, for general installation and configuration information.
- Calculate the current draw and voltage drop for your specific system using the Power Considerations section of the iQUBE2 Installation Manual.
- Mount the power supply in the provided 8 x 6 x 4-inch NEMA 4X FRP enclosure.
- Connect the transient protection board, PN 109396, to the power supply following the connections shown in Figure 1.
- Ensure that the voltage drop across the inductive chokes does not reduce the input voltage to the iQUBE2 system below the 6 VDC minimum.
Replacement Parts
If you need to replace any parts of the 12 VDC remote power supply, refer
to Table 1 and Figure 2 for the corresponding part numbers and quantities.
FAQ (Frequently Asked Questions)
Q: What is the maximum current provided by the power supply?
A: The power supply provides a continuous current of 3.7 amps.
Q: What is the rated power of the power supply?
A: The power supply has a rated power of 44.4 watts.
Q: What is the input voltage of the power supply?
A: The input voltage is 12 VDC.
Q: Where can I find more information about iQUBE2 installations and
configurations?
A: Refer to the iQUBE2 Installation Manual, PN 106113, for detailed
information about installations and configurations.
12 VDC Remote Power Supply Installation
This document contains procedures for installing the 12 VDC remote power
supply, PN 108434. This power supply is recommended for use in iQUBE2
installations that do not have AC power available at the scale platform.
See the iQUBE2 Installation Manual, PN 106113, for general installation and
configuration information. The Power Considerations section of that manual
includes a discussion of how to calculate current draw and voltage drop for a
given system.
WARNING: Disconnect Power before opening your supply enclosure.
CAUTION: Use a wrist strap to ground yourself and protect components from
electrostatic discharge (ESD) when working with circuit boards.
This power supply provides 44 watts of power, with continuous current of 3.7
amps, to power a full system over typical distances from scalehouse to scale.
The power supply is mounted in an 8 x 6 x 4-inch NEMA 4X FRP enclosure and
includes a transient protection board, PN 109396. The transient board option
for the iQUBE2, PN 110949, includes the transient protection board and a
mounting bracket for the iQUBE2 enclosure.
Figure 1 shows the transient protection board connectors. Wire the output DC
power cable from the V+ and V– terminals to the corresponding transient
protection board terminals in the iQUBE2 enclosure
The transient boards will handle the maximum current provided by the power supply, but large current loads increase the voltage drop across the inductive chokes and could reduce the input voltage to the iQUBE2 system below the 6 VDC minimum.
NOTE: When using 4-wire power cable, the cable voltage drop between the remote power supply and the iQUBE2 can be cut in half by using two wires for both the supply and return cable runs. Cabling can be doubled by wiring to both V+ terminals and both V– terminals on the transient board connectors.
