Model MX1236-L2 MicroFlex Series Uninterruptible Power Supply (UPS) is designed and primarily intended for use as a
DC power supply and battery back-up device for 12 Vdc Optical Network Terminals (ONTs) or similar communications equipment. The
MX1236-L2 Series can also be utilized in any 12 Vdc application where reliable DC power and battery are required. During normal
operation, the Micro UPS provides a constant supply of DC power and continues powering the equipment during an AC power outage.
Also available without battery as Model MX1236-P-C7.
