HySecurity MX000369 DC Power Supply Board
The HySecurity MX000369 DC Power Supply Board is a 3 amp DC power supply board used in compatible HySecurity Smart Touch operator systems. It supports the low-voltage DC power needs of compatible DC operator platforms and is commonly ordered during electrical repair when the existing DC power supply board has failed or been damaged.
Power supply board problems can create symptoms that look like controller failure, accessory failure, weak outputs, or intermittent operator operation. Before replacing a board, the incoming power, batteries, wiring, fuses, grounding, surge protection, and connected accessories should be inspected so the new board is not damaged by the same fault.
This part is commonly associated with StrongArm DC, SlideDriver DC, SwingRiser DC, and HydraLift DC model families. It is specifically the DC version and should not be confused with AC power supply board references.

Technician Note
Board replacement should be handled with the operator powered down and locked out. If the original board failed from lightning, water intrusion, shorted accessories, or incorrect voltage, correct that root cause before installing the replacement.
Before Ordering
- Confirm the operator is a DC HySecurity Smart Touch model
- Verify the installed board is the DC power supply version
- Compare connectors, board layout, and mounting points
- Inspect batteries, incoming power, accessory wiring, fuses, and surge damage
- Do not rely only on a number printed on the underside of the board
Important Ordering Warnings
- Do not confuse MX000369 DC with MX000487 AC
- High-voltage and stored-energy diagnosis should be performed by a qualified gate technician
- Do not bypass fuses, safety inputs, or grounding to make the operator run
Professional Advisory
HySecurity gate operator repairs often involve moving gates, stored energy, high voltage, batteries, and monitored safety devices. Electrical diagnosis and any unsafe gate movement should be handled by a qualified gate technician. Never bypass required entrapment protection or limit controls to keep an operator in service.
