When searching for a replacement, any rectifier with the following specifications should work:
The REC12-690+DC is built to withstand standard industrial environments, but its IP20 physical rating means it features protection against finger-sized solid objects (>12mm) while offering no native resistance to moisture or airborne fine dust. As such, it must always be housed securely within a sealed, NEMA-rated or IP-rated control cabinet or motor junction box. Critical Safety Protocols rec12-690 dc manual

This compact, high‑performance device is essential for heavy‑duty applications such as overhead cranes, hoists, elevators, and large material‑handling systems. * Category Semiconductors
| LED State | Condition | Action per Manual | | :--- | :--- | :--- | | Solid Green | Normal operation (output on) | No action. | | Slow Flashing Green | Standby (remote off) | Check remote inhibit pins. | | Solid Red | Output overcurrent or short circuit | Remove load, check for shorts. | | Fast Flashing Red | Input undervoltage ( <18V on input) | Check battery or source voltage. | | Alternating G/R | Overtemperature (internal >85°C) | Improve airflow, reduce load. | | Off completely | No input power or internal fuse blown | Check input fuse. If intact, unit likely failed. |
Check the input voltage (200-690V) to the module. If voltage is present, but no DC output, the rectifier module likely needs replacement. If voltage is present
: It rectifies incoming high-voltage AC utility or generator power into smooth DC output required by inductive brake coils.
