Dehner Elektronik SYS 1381N-1212-W2E fuente de alimentación AC/DC estabilizada 12W 12V DC con conector macho hueco 5,5x2,1mm

With 12 watts of stabilized DC output, this Dehner Elektronik SYS 1381N-1212-W2E power adapter delivers a rock-steady 12 V at 1.0 A for sensitive electronics that demand clean, regulated power. Efficiency Level VI keeps energy waste minimal, while short-circuit, overload, and overvoltage protection safeguard both the adapter and your device.

Overview

The SYS 1381N-1212-W2E is a fixed-voltage AC/DC plug-in power supply built for reliable everyday use. It accepts universal mains input from 100 to 240 V AC at 50/60 Hz, making it suitable for international use with a simple plug adapter. The Euro plug (CEE 7/16) fits standard European outlets, and the 1.5 m output cable ends in a 5.5 mm outer / 2.1 mm inner barrel connector with center-positive polarity — the most common configuration for small electronics.

What stands out

• Stabilized output: tight voltage regulation protects sensitive circuits from fluctuations.
• Efficiency Level VI: meets strict energy-efficiency standards, reducing standby and active power consumption.
• Comprehensive protection: short-circuit, overload, and overvoltage protection prevent damage to both adapter and device.
• Universal input: works with 100–240 V AC, so it can be used worldwide with the appropriate plug adapter.
• Durable construction: PC/ABS housing withstands daily use, and the operating temperature range of 0°C to +40°C covers most indoor environments.
