 Target Application Scenarios

12V 150A power supply for cryptocurrency mining rig

【Server Room Power】

Modern server racks and network storage arrays require stable 12V DC bus power at high current ratings. The KS-1800H-12V-150A server rack power supply delivers 1800W of continuous 12V power, supporting modular UPS backup systems, distributed server nodes and PoE switch arrays. The RS485/CAN port enables integration with facility BMS for real-time power monitoring.

【Cryptocurrency Mining Rig】

ASIC mining rigs for Bitcoin and Ethereum Classic run on 12V rail at high current. The KS-1800H-12V-100A (1200W) or KS-1800H-12V-150A (1800W) mining rig power supply provides dedicated, clean power per rig, reducing transformer heat and improving mining efficiency. The active PFC ensures stable operation even on fluctuating mining farm grids.

【Industrial Automation】

PLC controllers, industrial cameras, servo drives and AGV fleets all run on 12V DC rails. The KS-1800H-12V-50A (600W) industrial DC power supply suits individual PLC cabinets; the 80A model powers entire automation control panels. IP20 steel housing withstands industrial ambient conditions.

Key Technical Advantages

  • Active PFC (>0.95): Built-in active Power Factor Correction ensures grid compliance and reduces reactive power loss, critical for multi-unit deployment in server rooms and mining farms.
  • Forced Fan Cooling: Intelligent variable-speed fan adjusts cooling intensity based on load and ambient temperature, enabling 24/7 continuous operation at full rated current.
  • Multi-Protection Suite: OVP (Over Voltage Protection), OCP (Over Current Protection), OTP (Over Temperature Protection), and SCP (Short Circuit Protection) with auto-recovery.
  • High Efficiency (≥90%): Industry-leading efficiency minimizes heat generation, extends unit lifespan and reduces energy costs for continuous-duty installations.
  • RS485/CAN Communication: Optional communication port enables BMS integration for remote monitoring, load balancing and predictive maintenance in automated environments.
  • Constant Voltage Output: Stable 12V DC output with low ripple (<1%) maintains precision for sensitive server and automation electronics.
  • Wide Input Range: 200-240VAC input covers global industrial mains standards, with surge protection for unreliable grid conditions.

Q1: What is the difference between this 12v high current power supply and a standard battery charger?
Unlike a battery charger optimized for CC/CV charge termination profiles, the KS-1800H-12V series is designed as a Constant Voltage (CV) DC power source for continuous 24/7 operation. It can also function as a charging power supply for lead-acid or lithium battery packs when paired with a compatible BMS.
For a standard 1U/2U server rack with 12V distribution bus, the KS-1800H-12V-100A (1200W) handles most configurations. For high-density GPU server clusters or cryptocurrency mining farms requiring 1800W per rig, choose the KS-1800H-12V-150A (1800W). The 50A and 80A models suit individual PLC cabinets or small automation control panels.
Yes. The optional RS485 (Modbus RTU) or CAN 2.0B port enables direct connection to facility Building Management Systems (BMS) and battery BMS for real-time voltage/current monitoring, alarm reporting and remote shutdown in automated environments.
