Individual switches or grouped control (e.g., 1-to-5)?

Question

Accepted Answer

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. Electrical systems installed and tested at the factory. Related questions Standard ACB/contactor brands and upgrade options? Does the SR40 V3 include integrated power distribution?
