Electrical Safety & Control Systems

Short answer Yes — full factory customization is available for global grid standards, including North American configurations such as 415V/480V at 60Hz. All configurations are built to comply with local electrical codes and regulations. Full factory grid customization North America: 415V/480V, 60Hz Built to local electrical codes Configured before it ships How grid adaptation is handled Grid-specific electrical configuration is built in at the factory. Factory-configured, not field-modified. Voltage and frequency settings are engineered into the build before shipment. North American grids covered. 415V/480V at 60Hz configurations are standard customization work. Compliance is part of the build. Configurations follow the local electrical codes and regulations of the deployment region. Grid configuration settled during manufacturing. The load that depends on correct grid configuration. Tell us the grid before the build Voltage, frequency and local code requirements should be confirmed at ordering. Grid configuration is engineered into the factory build, so late changes cost schedule. Related questions Does the SR40 V3 include integrated power distribution?

Short answer Systems are equipped with top-tier industrial-grade components as standard. Upgrades to premium brands such as Schneider Electric or ABB are fully supported on customer request. Top-tier industrial components standard Schneider Electric upgrade supported ABB upgrade supported Quoted on request Component options OptionWhat you getAvailability Standard specificationTop-tier industrial-grade ACBs, contactors and electrical components.Standard on all systems. Premium brand upgradeComponents from brands such as Schneider Electric or ABB.Fully supported on customer request. What stays constant either way Electrical hardware — specifiable by brand at the customer's request. Industrial grade is the floor, not the ceiling. Even the standard specification is industrial-grade. Brand preference is accommodated. If your O&M standard requires a specific brand, the build can follow it. Upgrade options are engineered in. The platform supports the upgrade path rather than fighting it. The load these components switch and protect. Component specification is settled before assembly.

Short answer Sudden outages are handled by an automated recovery sequence. When power returns, the system first re-establishes water circulation; only once pressure and flow meet specification are the mining units brought back online — with no manual intervention required. Automated recovery sequence Circulation restored before hardware Pressure and flow verified first No manual restart needed The automatic restart sequence Power is restored — the system comes back after a grid outage. Water circulation restarts first — pumps re-establish flow through the loops before any hardware is energized. Pressure and flow are verified — the sequence waits until both meet specification. Mining units come online — hardware is brought back safely, in order, without manual intervention. Why the order matters Hardware only powers up once cooling is confirmed — never before. Cooling before compute. Energizing racks before flow is confirmed risks an immediate thermal event. Interlocks enforce the sequence. The PLC will not advance until conditions are met. Recovery without a site visit. The sequence removes the need for an operator to drive to the container. The load being protected by the sequence. Power restoration under PLC supervision.

Short answer Standard configuration uses high-density smart PDUs with grouped control, while every mining unit keeps independent protection through its own dedicated miniature circuit breaker (MCB) — so you get grouped switching convenience without losing per-unit fault isolation. High-density smart PDUs, grouped control Independent MCB protection per unit Grouped switching, isolated faults High-density electrical design Grouped control vs per-unit protection LevelWhat it controlsWhy it matters Grouped control (smart PDU)Switches units as a group — e.g. a 1-to-5 arrangement.Fast, coordinated power sequencing across a bay. Per-unit protection (MCB)Each mining unit has its own dedicated miniature circuit breaker.A fault on one unit trips only that unit's breaker. Inside the distribution design High-amperage distribution feeding individually protected circuits. Continuous high-amperage rating. PDUs are engineered for dense computing loads without derating. Breaker protection throughout. Circuit-level protection is standard, not an add-on. Tied into the PLC. Power and thermal management respond together. Individually protected units on the rack wall.
