100A 3-Phase Voltage Protector for ASIC Miners Over/Under Voltage & Phase Protection

3-Phase Automatic Voltage Protector (100A) protects industrial and household 3-phase equipment—including ASIC miners, motors, pumps, and sensitive electronics—from abnormal voltage conditions. The device automatically cuts power during unsafe voltage levels and reconnects when the supply becomes stable.

Mining Load Capacity (PF = 1)

On a 415V three-phase supply, a 100A system provides up to 71kW theoretical capacity. For safe continuous operation, it is recommended to use 80% load (~57kW).

Under this safe limit, the protector can support approximately:

• • Hydro Cooling ASIC Miners: 9–10 units (≈5.4kW each)
  • Air-Cooled ASIC Miners: 16–18 units (≈3.2kW each)

Actual capacity may vary depending on miner model and operating conditions.

This protector can operate as a complete 3-phase protection unit or as three independent single-phase protectors, making it suitable for ASIC mining farms, servers, pumps, and industrial equipment. It also provides real-time voltage and current monitoring with adjustable protection thresholds.

The device responds within 0.1 seconds to electrical faults including overvoltage, undervoltage, overcurrent, phase loss, and phase imbalance. The reconnect delay can be adjusted from 0.1–30 seconds.
