FAQs

What is the Delta MEA-160A C14 4 Pin DIN Series?

The MEA-160A is a 160W medical-grade AC/DC adapter with a C14 (IEC) input connector and a 4-pin DIN output connector, designed for medical devices requiring a detachable, certified power adapter.

What is the advantage of a C14 IEC input connector on a medical adapter?

The C14 connector allows a standard IEC mains cable to be used, making it straightforward to replace the mains lead for different regional plugs (Australian, UK, European, etc.) without replacing the adapter.

What is the 4-pin DIN output connector used for?

The 4-pin DIN connector is a common output format on medical adapters, providing a keyed, locking connection to the medical device to prevent accidental disconnection and ensure polarity safety.

What medical certifications does the MEA-160A hold?

Certified to IEC 60601-1 for medical electrical equipment safety, with 2×MOPP (Means of Patient Protection) input-to-output isolation — qualifying it for use in equipment operating in patient care environments and meeting IEC 60601-1 3rd edition leakage current requirements. DOE Efficiency Level VI compliant.

What input voltage does the MEA-160A accept?

Universal 90–264Vac (47–63Hz) single-phase input via the C14 IEC connector, covering Australian 230Vac mains and international 115Vac without manual switching.

How does the MEA-160A compare to the MEA-250A and MEA-300A?

The MEA-160A (160W) is the lower-power medical adapter; the MEA-250A (250W) and MEA-300A (300W) are for higher-power devices. All share the IEC 60601-1 medical certification.
