Information about MEAN WELL GST120A12-R7B
The MEAN WELL GST120A12-R7B is a highly reliable, fanless desktop power adaptor engineered as part of MEAN WELL's energy-saving green power series. Achieving compliance with stringent Level VI efficiency standards and consuming an extremely low no-load power of under 0.15 W, this unit offers maximum energy conservation in active and standby modes. Delivering a stable 12 V DC output at up to 12.5 A, it serves as a robust power source for sensitive electronic equipment, commercial systems, and demanding industrial applications across global markets thanks to its universal 85 to 264 V AC input range.
Featuring a 4-pin Power DIN connector with lock mechanism (R7B), the power supply guarantees a secure, vibration-resistant output connection that prevents accidental disconnection. It is built with integrated active PFC functionality for optimal power factor performance and employs a fully enclosed 94V-0 flame-retardant case. Designed to operate silently without a fan across a broad thermal envelope of −30 °C to +70 °C, the unit integrates comprehensive protection circuits covering short circuits, overloads, overvoltages, and overtemperatures, all backed by international safety approvals and a 3-year manufacturer warranty.
