REC12-690+DC Rectifier Brake Module Overview The REC12-690+DC Go to product viewer dialog for this item.
is a specialized electronic component primarily utilized in heavy industrial machinery, such as cranes, elevators, and escalators. Manufactured by brands like Konecranes and SWF, this half-wave rectifier module is designed to manage the transition from alternating current (AC) to direct current (DC) while providing critical dynamic braking capabilities. 1. Key Technical Specifications
According to documentation from AnZhou and industrial suppliers, the module operates under the following parameters: Input Voltage Range: AC 200V to 690V. Output Voltage: DC 90V to 310V (calculated as
Current Ratings: 1.25A to 12A RMS for continuous operation, with intermittent peak handling up to 150A. Operating Temperature:
, allowing for use in harsh environments like mining or coastal installations. The Ultimate Guide to the REC12-690 DC Manual:
Protection Rating: IP20, meaning it is protected against large solid objects but requires an enclosed cabinet to prevent dust or water ingress. 2. Functionality and Use Cases The module serves two primary roles in power systems:
Rectification: Converts AC from stator windings into DC for excitation systems.
Dynamic Braking: Acts as a safety mechanism to dissipate excess electrical energy generated during sudden load drops or motor shutdowns. By channeling surplus voltage through high-power resistors, it prevents overvoltage damage to sensitive control circuits.
Applications: Frequently integrated into Konecranes hoist systems and other lifting equipment requiring precise braking control. 3. Installation and Safety Guidelines
Based on industrial manuals for similar 690+ series modules, such as those from Parker SSD, users should adhere to the following:
Qualified Personnel: Installation and maintenance must be performed by technicians familiar with high-voltage safety practices. Input (AC): Connect your 3-phase AC supply (typically
Earthing Requirements: The equipment must be permanently earthed due to high earth leakage currents.
Hazardous Voltages: Be aware that dangerous voltages may still be present at power terminals (DC bus and brake) even when the motor is at a standstill.
Warranty Awareness: Unauthorized repairs, improper voltage use, or fitting non-genuine parts will void the manufacturer's warranty. 4. Procurement and Availability REC12-690+DC Go to product viewer dialog for this item.
