Official immersion multi-bin reference: Canaan publishes the Avalon Miner A1566I in the exact 249T and 261T lanes below. Canaan categorizes the I-suffix product under immersion cooling.
| OEM bin | Hashrate | Wall power | Efficiency | Input voltage |
|---|---|---|---|---|
| A1566I-249T | 249 TH/s, ±5% | 4,500 W, ±10% | 19 J/TH, ±5% | 220–277 V AC |
| A1566I-261T | 261 TH/s, ±5% | 4,500 W, ±10% | 17.8 J/TH, ±5% | 220–277 V AC |
Both exact listings publish 292.5 × 171.5 × 281–301 mm net dimensions, 10.6–11.3 kg net weight, 390 × 290 × 395 mm gross dimensions, and 11.6–12.3 kg gross weight. The PSU is included without a power cord.
270T and 273T performance conflict
Canaan identifies A1566I-270T and A1566I-273T products, but its current catalog/immersion collection prints 4,959 W while the direct product bodies print 4,500 W. This reference acknowledges those identities but withholds their performance matrices until Canaan resolves the power conflict or exact nameplate evidence is available.
Electrical and immersion-system boundaries
The exact 249T and 261T pages publish 220–277 V AC, but do not publish frequency, input current, connector, immersion-fluid chemistry or dielectric requirements, flow, pressure, fluid temperature, tank compatibility, filtration, facility heat-rejection capacity, noise, or operating-temperature limits. Do not infer these fields from A1566 air, A1566HA hydro, another immersion miner, or a generic template.
Qualified electrical and immersion-facility design is required. Match the complete suffix and nameplates to the current Canaan manual, then have qualified professionals verify the circuit, conductors, protection, connectors, bonding, compatible dielectric fluid, circulation, filtration, heat rejection, leak/spill controls, monitoring, and local requirements. This reference is not an electrical or immersion-system design.
Firmware and recovery
Use only an exact A1566I package matching the bin and installed hardware revision. The A1566 family name does not establish compatibility with air or HA hydro variants.
- Record the full suffix, bin, installed version, and fault logs.
- Use Canaan’s exact-model firmware and document picker.
- Follow matching FMS, Avalonbuddy, or AvalonUpgradeTool instructions only after the package match is proven.
- For electrical, immersion-loop, thermal, hashboard, physical, or no-boot symptoms, request diagnosis.
Known boundaries: no unpublished electrical or immersion-loop value, noise, operating temperature, ASIC model/count, universal controller, tuning, profitability, home-suitability, price, release date, or lifecycle status is asserted.
