80A Genarator Diod / Bridge Diod 4 Leg (QL80A 1000V) Code: 27038985

The SQL 80A 1000V (sometimes referred to as QL80A/SQL80A) is an industrial-grade, single-phase (or sometimes three-phase depending on the specific module wiring) power bridge rectifier designed to convert high-current alternating current (AC) into direct current (DC).

Key Technical Specifications

• Average Forward Current :80A
• Peak Repetitive Reverse Voltage:1000V
• Phase Type:Single-phase (4 terminals)
• Structure:Consists of 4 power diodes connected in a bridge configuration inside a single insulated package.
• Mounting/Casing:Metal or aluminum casing with an electrically insulated base (usually requires a heatsink for operation at maximum current).

Terminal Configuration

The module typically features 4 terminals clearly stamped with standard electrical symbols:

• ~or AC: The two terminals in the middle connect to the AC power source.
• + (Positive): The DC positive output.
• – (Negative): The DC negative output.

Operating Conditions & Thermal Management

• Operating Temperature:Typically rated between -55°C to +150°C.
• Heatsink Requirement:While the module is rated for 80A, running it at high continuous currents will generate substantial heat. A dedicated heatsink and thermal paste are required to prevent thermal breakdown.

Common Applications

• Industrial automation and control equipment.
• Power supplies and battery chargers.
• DC motor drives and controllers.
• Generator rectifiers and welding equipment.
