AC PCB UNI Inverter QD-82U+2

Description

Product Description: QUNDA QD82U+ Universal Inverter Air Conditioner Control System The QUNDA QD82U+ is an advanced, comprehensive universal mainboard replacement kit designed specifically for DC and AC Inverter split air conditioning systems. While standard universal boards only work with older fixed-speed (ON/OFF) compressors, the QD82U+ is engineered to drive modern energy-efficient inverter compressors up to a high capacity of 24,000 BTU. This premium service kit replaces both the indoor and outdoor electronic circuit boards (PCBs). It includes an indoor board, a heavy-duty outdoor module with integrated cooling sinks, a full-featured digital LED display panel, a wireless remote control, an electronic expansion valve (EEV) driver terminal, and a complete array of temperature sensors for precise thermal regulation. Key Technical Specifications Model: QD82U+ (High-Capacity Inverter Repair System) Maximum Capacity: Handles systems from 18,000 BTU up to 24,000 BTU (approx. 2.0 HP to 2.5 HP) Power Input: 220V–240V AC, 50/60 Hz Compressor Drive Type: Capable of driving strong DC Inverter Compressors or traditional AC Inverter Compressors. Fan Motor Support: Drives both indoor and outdoor DC or AC fan motors (including PG feedback styles). System Controls: Built-in control logic for electronic expansion valves (EEV), 4-way reversing valves (for heating/cooling changeover), and continuous diagnostic error monitoring. Compatible Machines & Brands The QUNDA QD82U+ is a universal system, meaning it is not restricted to one specific manufacturer. Instead, it is compatible with virtually any wall-mounted, fixed-ductless inverter split system within its tonnage rating that requires an entirely new electronic control architecture. Compatible System Configurations Inverter Air Conditioners: Specifically built for variable-speed inverter models (not for older single-speed, non-inverter machines). Component Versatility: It works whether your existing system uses a DC compressor or an AC compressor, and matches both AC or DC outdoor fan configurations. Commonly Retrofitted Brands When original inverter power modules or mainboard assemblies become obsolete, out of stock, or too expensive to source, technicians use this board to save systems from the following global brands: Midea / Carrier / Toshiba: A very frequent target for retrofits due to similar sensor profiles and valve setups. Gree: Fits a vast range of residential inverter lines up to 2.5 HP. Samsung & LG: Commonly used to replace discontinued Smart Inverter power boards. Panasonic: Restores operations to non-communicating or older variable-speed split units. Daikin: Compatible with standard inverter configurations (excluding specialized multi-split or VRV communication networks). Voltas, Lloyd, & Hisense: Restores operation to local high-capacity home cooling systems.
