MEAN WELL GST120A20-R7B 120W 20V 6A pöytävirtalähde

Desktop power supply delivering a stable 20V DC output at up to 6A (120W) from a universal 90-264VAC input. The GST120A20-R7B combines high efficiency with a compact, fully enclosed plastic case, making it ideal for powering monitors, industrial terminals, and other DC devices.

Advantages

With an efficiency above 90% and no-load consumption under 0.15W, this unit meets DOE Level VI and ErP Stage 2 standards, reducing energy costs and heat. Comprehensive protections against short circuit, overload, over voltage, and over temperature ensure reliable operation. The wide operating temperature range from -30°C to +70°C and free air convection cooling allow deployment in demanding environments without fan noise.

Suitable for

• Industrial monitors and displays
• Point-of-sale terminals
• Networking equipment requiring 20V DC
• Test and measurement instruments
• Any device with a 2.5x5.5mm barrel jack, center positive
