The is a rectifier bridge module specialized for brake control in high-power lifting applications. It acts as a converter, taking AC voltage input and converting it into a specific DC output required by the brake coil of a crane motor.

Bridge Rectifier, typically Blue Plastic housing. Weight: Approximately 0.132 – 0.25 lbs. 3. REC12-690+DC Installation and Troubleshooting : Designed for continuous operation at roughly 1

: The integrated "+DC" circuitry functions as a surge suppressor. It absorbs high-voltage inductive spikes (back-EMF) generated when the brake coil is suddenly switched off.

: Converts AC from stator windings into DC for excitation systems.

Check DC Output : If AC input is present but DC output reads 0V, the internal diode bridge of the REC12-690+DC has failed. The module must be replaced. Technical Specifications Overview This public link is valid

The typical REC12-690 DC rectifier has the following technical specifications:

The REC12-690 DC converter can be operated in single-quadrant or dual-quadrant mode. In single-quadrant mode, the converter can only operate in one direction, while in dual-quadrant mode, it can operate in both directions. The manual provides detailed instructions on how to configure the converter for each operating mode.

Always isolate all upstream AC and DC power sources before removing the chassis cover or altering any wiring connections.
