The BTPSU05KSA-01.00 is the original switching power supply unit (PSU) for the Bitdeer SealMiner A2 miner. Featuring a dual-channel DC output design, it provides stable power to both the A2 hash boards and the control board. It supports a wide range of high-voltage AC inputs and offers high conversion efficiency. As an official replacement component, it is designed specifically for the air-cooled SealMiner A2, providing an ideal power solution for mining farm operations, maintenance, and spare-part replacement.
1. Original factory precise compatibility
The original power supply for the SEALMINER A2 air-cooled unit is fully compatible with the hardware protocol and copper busbar interface, allowing for immediate use without the need for rewiring.
2. Wide Voltage and High Voltage Input
Supports 220~277V high-voltage AC input, adapts to high-voltage mining farm power supply architecture, has stronger voltage fluctuation tolerance, and is suitable for large-scale mining farm cluster deployment.
3. Dual independent power supply
A 15V high-current main circuit supplies power to the ASIC chip, while a separate 12.3V auxiliary circuit supplies power to the control board, providing power isolation and improving overall stability.
4. High-reliability industrial-grade solution
Designed for long-term full-load operation specifically for mining machines, with continuous high current output and a heat dissipation structure matched to the A2 chassis airflow, suitable for 24/7 uninterrupted mining operation.
1. Replacement of faulty power supply units in SealMiner A2 miners.
2. Provisioning of original power supply units for new mining farm deployments.
3. Deployment in mining farms utilizing high-voltage power grids (240V/277V environments).
4. After-sales maintenance and hash-rate restoration for mining equipment.
