MikroTik G1270 750W Dual-Output Open Frame Power Supply 53Vdc 26.5Vdc

The MikroTik G1270 is an open-frame 750W replacement power supply unit engineered specifically for the CRS354-48P-4S+2Q+RM managed switch. Delivering dual DC output rails, it provides the regulated voltages required to sustain the switch's high-density PoE and switching workloads. Its wide-range AC input accepts voltages from 90 to 264Vac, making it suitable for deployment in North American and international facilities without manual voltage selection. As a direct form-factor replacement, the G1270 allows service teams to restore failed PSUs in the field while maintaining the original chassis footprint and electrical integrity of the CRS354 platform.

Key features & benefits

• Dual DC Output Rails — Supplies two independent regulated outputs—53Vdc at 13.5A and 26.5Vdc at 27A—meeting the distinct power requirements of the CRS354-48P-4S+2Q+RM switching and PoE subsystems.
• 750W Total Power Capacity — Delivers up to 750 watts of continuous output power, providing the headroom needed to sustain a fully loaded PoE switch with multiple high-draw endpoints connected simultaneously.
• Wide-Range Universal AC Input — Accepts AC input from 90 to 264Vac, enabling reliable operation across a broad spectrum of global utility voltages and generator-supplied power environments without manual adjustment.
• Open-Frame Design — The open-frame construction facilitates direct chassis integration and airflow alignment within the CRS354-48P-4S+2Q+RM enclosure, simplifying replacement procedures for qualified technicians.
• Purpose-Built Replacement Unit — Designed as a factory-specified replacement for the CRS354-48P-4S+2Q+RM, ensuring electrical compatibility and mechanical fit without modification to the host switch chassis.
