Valve Control Panel Design

We designed a control panel operating a set of valves in a pastefill system underground. The panel required a full uninterruptible power supply to ensure that the valves could still be operated in the event of a power failure, preventing potential damage to millions of dollars of infrastructure.

We came up with an extra low voltage (ELV) design system that could be hooked into the mine’s 1000V underground power reticulation.  The ELV system provides two benefits;

• The operator safety operating at ELV significantly decreases the hazards of electric shock
• We were able to design the system so that the UPS storage component was manufactured using 12V car batteries, as these were going to a remote mine there would be parts readily available in the event of equipment failure.
