Sega Genesis Model 1 AC Adapter MK-1602 Specifications

Sega Genesis Model 1 AC Adapter MK-1602 Specifications

The official part number for the Sega Genesis Model 1 AC adapter is MK-1602. This adapter was specifically designed to power the Genesis Model 1 console, as well as other Sega hardware like the Sega CD Model 1 and the Sega Master System. Here’s a detailed technical breakdown of its specifications and compatibility:

Technical Specifications

1. Output Voltage:
   • The adapter outputs 10V DC. This voltage is slightly higher than the 9V standard used by some other consoles, ensuring stable operation for the Genesis Model 1.
2. Current (Amperage):
   • The adapter provides 1.2A (1,200mA) of current. This is more than sufficient for the Genesis Model 1, which typically draws less than 1A during operation. The higher current capacity ensures the adapter can handle power spikes without overheating.
3. Polarity:
   • The adapter uses a center-positive polarity configuration. This means the inner pin of the barrel connector is positive (+), and the outer sleeve is negative (-). Using an adapter with the wrong polarity can damage the console.
4. Connector Type:
   • The adapter features a barrel plug connector. The dimensions of the plug are designed to fit snugly into the Genesis Model 1’s power input port, ensuring a secure connection.
5. Input Voltage:
   • The adapter is designed for 120V AC input at 60Hz, which is standard for North American electrical outlets.

Compatibility

• Sega Genesis Model 1: The MK-1602 is the official power supply for this console.
• Sega CD Model 1: Fully compatible, as the power requirements are identical.
• Sega Master System: Also compatible, as it shares the same voltage, current, and polarity specifications.

Identifying the MK-1602

• The part number MK-1602 is typically printed on the label of the adapter, along with its electrical specifications.
• The label also includes safety certifications and the Sega logo, ensuring authenticity.

Important Notes

• Do Not Use with Genesis Model 2 or 3: These later models require different adapters with lower voltage and different connector types.
• Third-Party Replacements: If the original MK-1602 is unavailable, ensure any replacement adapter matches the exact specifications (10V DC, 1.2A, center-positive) to avoid damaging your console.
