Compatibility evidence
- A specialist supplier identifies Dewert Ultra Control Box 50757/51683 and P/N 990.761.001 on obsolete lift-chair power boxes. This is third-party identification evidence, not current manufacturer documentation.
- That supplier offers a retrofit kit for many older single-motor Pride lift chairs with a Megamat MBZ or specified two-prong motor. Its Y-harness, new power supply and two-button handset replace the old electronics while retaining the actuator; suitability is conditional on the exact installed system.
The linked retrofit kit is NOT a plug-in replacement control box and is NOT an OEM-approved universal fit. Do not assume part 990.762.001, CTLDC1301 or model 50757/51683 is interchangeable solely by number. Check the original label, chair/actuator model, motor cable, handset connector and full supplier installation requirements before purchase; disconnect mains power before inspection. No original voltage or pinout has been established.
