Problems solved by technology

However, the cost of such board systems can be relatively high and reliability can be an issue
Furthermore, such systems require user time and effort to switch boards and rely on the user to have checked that the correct board is in place or to switch boards for the correct voltage
This is a disadvantage and may allow wrong voltages to be connected

Embodiment Construction

[0061] will now refer to Figures 1 to 7 Preferred embodiments are described.

[0062] figure 1A multi-voltage electrical device 1 wired in series (A and B) and parallel (C and D) is shown in . The electrical load in one preferred form is a flat coil of resistance wire or heater cable having a given resistance per length (ohm / meter). Such planar arrays in the form of resistive wires are demonstrated in figure 2 , wherein the planar array is a pad heater 15 . A skid heater 15 as previously described is used to heat the contents of an IBC 9, such as image 3 shown in . Such as image 3 As shown in , a skid heater 15 is positioned or incorporated in the assembly between the bulk container 9 containing the product to be heated and the pallet 17 on which the container 9 rests. Since the container contents will typically weigh over 1000 kg and the container 9 is fragile, in most cases the skid heater 15 is positioned below the container 9 and above the pallet 17 (or equivale...

Abstract

Disclosed is a multi-voltage electrical apparatus comprising or including, an electrical load that can connect via an electrical connection separately to both of either, a first electrical source at afirst voltage, and a second electrical source at a second voltage. The electrical load is connected in series via the electrical connection to the first electrical source, or in parallel via the electrical connection to the second electrical source. The electrical load when connected in series or parallel having substantially the same power output.

Description

technical field [0001] The present invention relates to electrical connections for slide heater pads. [0002] The invention is particularly, but not exclusively, concerned with dual voltage connectors which are passive and allow connection to one voltage or the other to power universal slip heater pads such as for heating intermediate bulk containers (IBC). Background technique [0003] Problems arise when products requiring electrical connections are migrated from one country to another. This problem is further compounded when it migrates from one country to another with a different level than those, for example Australia or New Zealand is 230VAC, while the US is 115VAC. [0004] There are various solutions so far. [0005] One solution to connecting the same thing to two voltages requires an active power supply to step down or step up the voltage to the operating voltage of the connected device. This poses problems of increased cost and potential power supply vulnerabi...
