Key Technical Advantages for Overseas Integrators
High Inrush & Peak Load Immunity
Unregulated power supplies rely on robust linear transformers and heavy-duty rectifiers, enabling them to absorb high peak inductive currents without triggering electronic shutdown switches.
Exceptional Operating Lifespan
With minimal electronic components compared to complex switching power supplies, these units offer extraordinarily high MTBF values under continuous heavy industrial operation.
Guaranteed 3-Day Dispatch
Acopian manufactures every power supply fresh after receiving your order at our Easton, PA and Melbourne, FL plants, shipping within 3 business days worldwide.
