Crestron® CEN-UPS1250 Uninterruptible Power Supply with managed power control and surge protection

Get to know this product.

An advanced UPS and power management solution designed to provide ultra dependable device protection with seamless control system integration.

The CEN-UPS1250 is a 1250 Watt, 120 Volt uninterruptible power supply and power conditioner Engineered by APC® specifically for Crestron®. Designed to protect Crestron control systems, media servers, video displays and other devices, the CEN-UPS1250 employs pure sine wave battery backup to maintain continuous operation of critical components whenever power is disrupted. Remote monitoring and control through award-winning Crestron RoomView® software, and full Crestron control system integration, deliver a comprehensive power management and protection solution that's an integral part of the complete Crestron control network.

Pure Sine Wave Battery Backup

    Any unexpected shutdown due to the sudden loss of power will certainly disrupt workflow and stop a presentation dead in its tracks, but it can also cause the loss of precious data and system settings, and can even damage hard drives and other vulnerable components. The CEN-UPS1250 constantly monitors the incoming power line and instantly transfers power to battery backup in the event of such a power loss, ensuring the connected components continue to operate unhampered. It may also be configured to transfer to battery in the case of an over or under voltage condition, or if excessive line noise or distortion is detected, ensuring optimum performance of sensitive video and audio equipment during momentary power glitches.

    When running on battery backup, the CEN-UPS1250 can power a rack full of equipment for several minutes without interruption. In the event of a prolonged power outage, a properly managed shutdown of the equipment can be performed automatically. Configurable "load-shedding" allows only certain components to be shut down, preserving battery fuel and extending runtime for more vital components. The CEN-UPS1250 will also ensure a smooth changeover from primary power to a backup generator.

Managed Power Control

    The CEN-UPS1250 provides twelve 120V power outlets organized in 4 banks. Each of the four banks of outlets is independently switchable, with fully managed power-up and shutdown available at the press of a single button or control system command. Up to 10 seconds of delay adjustment on banks 3 and 4 enables customized sequential switching capability. Sequential switching ensures that all the components of a complete system are powered up and down in proper order, avoiding dangerous transients that can damage delicate components and trip the main circuit breaker. Components such as video projectors and media servers that require systematic shutdown and restart can be managed seamlessly through integration with a control system.

Automatic Voltage Regulation

    Keeping the voltage within a safe operating range helps prevent equipment malfunctions and can even improve audio and video performance. Using automatic voltage regulation, the CEN-UPS1250 can correct for many high and low voltage fluctuations without having to switch to battery operation, preserving battery fuel for more serious situations.

Surge Protection

    The CEN-UPS1250 provides thorough protection against surges, spikes, and lightning. In addition to power line protection on all 12 outlets, there is also built-in surge protection for two separate coax lines and one telephone line, delivering a complete solution for protecting TVs, cable and satellite receivers, modems, and conferencing devices.

Noise Filtering

    Built-in EMI and RFI noise filtering eliminates the electromagnetic and radio frequency interference that can negatively impact sound and video quality. Each of the four outlet banks provides filtering protection specialized for a specific type of device: DIGITAL, DISPLAY, ANALOG, and HI-CURRENT. Each bank is electrically isolated to prevent any noise present on one bank from reaching the devices connected to any other bank.

Environmental Monitoring

    Using the external probe included, ambient temperature and relative humidity levels can be measured and recorded, and even reported to the control system or central help desk. Using this feature, safe operating limits can be specified for all of the equipment within a room or rack so that whenever the limits are exceeded, the user is notified, climate control is adjusted, and if necessary the equipment can be powered down safely.

RoomView™ and Control System Integration

    Monitoring and operation of the CEN-UPS1250 extends beyond its front panel, providing direct communication with Crestron RoomView Remote Asset Management Software as well as with Ethernet-enabled Crestron control systems. The CEN-UPS1250 notifies RoomView whenever it switches to battery backup, and warns if the battery is low or overloaded. It also reports which outlet banks are on, as well as the line voltage, output voltage, frequency, voltage regulation status, system load, internal temperature, ambient temperature and humidity, and battery condition. Centralized monitoring and logging via RoomView provides an invaluable resource for quickly resolving power line problems and maintaining batteries.

Built-in Logging

    In addition to RoomView, the CEN-UPS1250 also supports onboard data and event logging. Data can be set to log every 10 seconds to 18 minutes with sufficient memory for at least 30 days of history, recording the load, battery condition, line voltage, outlet on/off status, and environmental conditions. Instantaneous events such as switching to battery, low battery warnings, and self-tests are also logged.


    A heavy duty rackmount hardware kit is provided to mount the unit into any EIA standard 4-post 19" equipment rack up to 28" deep. The feet on the bottom of the unit can be unscrewed and removed to save space when the unit is rack-mounted.
