AC/DC Power Supply, 1 Output, 12 W, 12 V, 1 A WSU120-1000-R
Description
WSU120-1000-R is a compact, fully enclosed external AC-to-DC power supply designed for plug-in use. With a regulated 12 V output at 1 A (12 W), it is ideal for powering electronics, embedded devices, or auxiliary circuits without the need for internal power supply design.
Key Features & Benefits
- Wide input range: Operates from 100 VAC up to 240 VAC, 50–60 Hz, making it suitable for global voltage environments.
- Regulated output: Provides 12 V DC at up to 1 A with stable performance across load variation.
- Compact plug-in form factor: Eliminates the need for internal PSU heatsinking or ventilation; reduces noise, size, and heat in host applications.
- Safety & isolation: Double-insulated construction (Class II), dielectrically isolated to 4 kV DC for one minute.
- Polarity & connector: Uses a barrel plug (2.1 mm × 5.5 mm × 11 mm) with center-negative polarity.
- Efficiency & compliance: Meets regulatory efficiency standards (Level VI / EISA 2007) for external power supplies.
