(1PCS) GENUS PROTON 850VA Refurbished CONTROL CARD

Genus Proton 850VA is a popular Home UPS (HUPS) known for its DSP-based sine wave technology. When dealing with a refurbished control card, the goal is usually to restore the “brain” of the inverter so it can properly manage battery charging, MOSFET switching (PWM), and fault protection.

​1. Control Card Overview

​The control card is a small PCB that plugs into the main motherboard. In refurbished units, it has typically been “OK tested” to ensure the pre-programmed microcontroller is functioning and the SMD components are within spec.

• ​Technology: DSP (Digital Signal Processor) Sine Wave.
• ​Voltage: 12V DC system.
• ​Key Components: * Microcontroller: Pre-loaded with Genus firmware.
  • ​Driver ICs: Often uses the MC33883 or dual-gate driver ICs to trigger MOSFETs.
  • ​Transistors: Common SMD types like MMBT2222A (1P), SS8050 (Y1), and SS8550 (Y2).
