Power it
Off-road electrification, switched and connected
Electric construction and mining machines run on DC that never crosses zero. Schaltbau DC contactors clear the arc with permanent-magnet blowout in an open chamber, bidirectional, to 3,000 V, with shock and vibration ratings for the machine; HV connectors at 1 kV and 470 A, and LV connectors to 500 A for the forklift and the yard tractor.
AC on the machine, from the pack
An electric mining utility truck runs welders and compressors on three-phase AC from its own battery: ODX-6000 6 kVA inverters, parallelable, built for dust, vibration and temperature extremes. OPS-260 inverters sealed to IP66 for the open deck, CMS-2000 DC/DC to IP69K from a 180 to 950 V pack, and -40 to +70 C ranges available across the line.
Heat and motion switched with nothing to wear
Solid state relays for cab heat, hydraulic-oil heaters, and the motor reversing and soft-start duty on a crane or hoist, 4 to 125 A, no contact to bounce on a bump. Magnetic and reed sensors for door, boom and position detection, sealed, stainless versions for the wet end.
Portable power to the work
Power distribution on a hand truck: 30 A in, a step-down transformer and surge protection on board, outlets where the crew is working. Portable PDUs from 40 to 400 A with GFCI-protected outlets, genset and emergency-power inlets ready before the outage, drive-over cable bridges for the yard. UL Listed and CSA Certified pin and sleeve.
Control it
Drives built for vibration
Jaguar drives including harsh-environment models built for vibration, for the irrigation pump, the conveyor and the crusher feed; contactors and motor circuit breakers from compact to heavy frames; iSmart smart relays and XGB PLCs with license-free programming for the pump house and the wash bay. Same-day dispatch from US stock.
Input that works with gloves on
Capacitive keyboards and switches that read a gloved hand through a sealed front, stainless steel keypads that shrug off weather and abuse, optical switches with no moving part, and InduSmart panel PCs with an IP65 front for the cab and the service bay.
Prove it
-40 to +80 C, in the cabinet on the machine
Compact unmanaged switches on the DIN rail that hold -40 to +80 C in a roadside cabinet, and board-level Ethernet 55 by 55 by 10 millimeters designed into the machine's own controller. Sealed-enclosure networks that have gone subsea on inspection vehicles.
Field to the office over fiber
Managed switches with SFP fiber ports carry the sensor network across a farm or a pit, past the distance and the EMI copper cannot, and put the legacy PLC and the new sensors on one network. Sixteen ports on one DIN-rail footprint when the cabinet is full.
Machine state without touching the controller
Remote I/O reads run states, counts and temperatures at the sensor and presents them as Modbus TCP devices the fleet or plant system polls, on a machine whose controller is off-limits. The manual station counts too: a pushbutton or a foot switch is a digital input.
Every charger feed, one device
BFM-II meters up to 54 single-phase or 18 three-phase circuits from one DIN-rail unit, against two voltage sources. Each depot charger, the pump station and the shop carry their own kWh, so the demand charge has a face. HACS split-core sensors clip on around the conductor, so it goes into a yard that is already running.
Foundation
Terminals and entries that take the vibration
Spring-clamp terminal blocks that hold under vibration, KDS-FB flat-cable entries built for industrial trucks, cranes and elevators, and KDS split entries that pass a pre-terminated harness through a sealed wall, IP66 from -40 to +120 C.
Junction boxes built for outside
COMBI junction boxes to IP66, UV and ozone resistant, quarter-turn lids, membrane entries that need no locknut, for the pump house, the pole and the pit. Glands, venting and the Brace conduit system around them, from a company that started on ships in 1919.
