The module is engineered for high-voltage industrial environments, featuring robust thermal management for heavy-duty cycles. Specification AC 200–690V Output Voltage DC 90–310V (Formula: Maximum Current 1.25A DC (Continuous) Operating Temp -25°C to +60°C Ingress Protection IP20 (Requires enclosure) 2. Installation and Wiring
The REC12‑690+DC brake rectifier is a key component in industrial braking systems. It is a line‑voltage, half‑wave rectifier specifically designed to convert alternating current (AC) to direct current (DC) for the brake coils of electromagnetic holding brakes. Low Voltage Deep discharge or long storage Attempt
The REC12-690 DC power supply is a highly efficient, compact, and reliable device that converts AC input voltage to a regulated DC output voltage. The device features a robust design, high power density, and a wide range of protection features, making it suitable for a variety of applications, including:
The is a critical, heavy-duty electronic component engineered to stabilize power supplies and manage electronic braking mechanisms in industrial machinery . Most notably used in cranes, hoists, generators, and KONE elevator systems , this rectifier converts alternating current (AC) into direct current (DC) to power and control electromagnetic brake coils safely and efficiently.
| Parameter | Value / Condition | Notes | |:---|:---|:---| | | 200 ... 690 VAC, 50/60 Hz | Automatically adapts to the supplied AC voltage | | Configuration / Type | Half‑wave rectifier | Uses a half‑wave design for economy and efficiency | | DC Output Voltage (No Load) | Approx. 0.45 × U AC | The actual voltage depends on the AC input and coil load | | Maximum Continuous DC Output Current | 1.25 A DC | Sufficient for most industrial brake coils | | Line Voltage | Up to 690 VAC | Operates directly on the motor's AC line voltage | | Brake Control Logic | External brake contactor (K7) | The DC circuit is completed by shorting the 'a' and 'b' terminals via the K7 contactor | | Protection | Built‑in varistor | Absorbs voltage spikes from the brake coil to protect the contactor and rectifier | | Operating Temperature | –10 °C to +40 °C | Standard industrial range | | Enclosure Rating | IP20 (typical) | For installation inside a control panel or electrical enclosure |
: When power to the motor contactor is cut, the power feed stops. The "+DC" suppression loop quickly dampens the inductive energy left inside the coil, collapsing the magnetic field instantly. Heavy internal springs then push the brake shoes against the motor shaft to hold the load. 5. Maintenance and Troubleshooting
: Installation and maintenance must be performed by technicians familiar with high-voltage safety practices.
