Phoenix Contact's UNO-UPS is a compact, 24 V_DC solution used to provide standby power in the event of an AC mains power loss. This UPS is perfect for compact controllers, PLCs, HMI, and other low-power devices. This cost-effective UPS includes an integrated 0.8 Ah VRLA, absorbed glass mat (AGM) lead-acid battery. This battery allows for application temperatures from -15°C to 50°C. This AGM battery can be expected to last for up to five years.

LEDs indicate the unit’s operational condition. The status may also be communicated to a supervisory control system through the integrated status contacts. Additionally, the battery runtime can be adjusted by a rotary dial to prevent the battery from being deep-discharged. Runtime may also be controlled through remote shutdown input. An external 24 V_DC power supply is required to supply input power to the UNO-UPS. The UNO AC-to-DC power supply, P/N 2902992, is an ideal choice to power this UPS.
