Crestron CEN-UPS1250 Uninterruptible Power Supply
Uninterruptible Power Supply:
CEN-UPS1250
Introduction
Features and Functions
• UPS and power conditioning – Engineered by APC®
• 2-Series control system integration
• Centralized management via RoomView®software
• Battery backup and power control management
• Surge protection for power line, coax and telco
• Isolated EMI and RFI noise filtering
• Automatic voltage regulation
• Built-in environmental monitoring
• Onboard timestamp logging
• 19” four post EIA rack mountable
Uninterruptible Power Supply
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 Crestron’s award-winning RoomView®software and full
2-Series control system integration deliver a comprehensive power management and
protection solution that is 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
Operations & Installation Guide – DOC. 6635A Uninterruptible Power Supply: CEN-UPS1250 •1

Uninterruptible Power Supply Crestron CEN-UPS1250
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 120 Volt power outlets organized in four 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 included external probe, ambient temperature and relative humidity levels
can be measured, 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.

Crestron CEN-UPS1250 Uninterruptible Power Supply
RoomView®and Control System Integration
Monitoring and operation of the CEN-UPS1250 extends beyond its front panel,
providing direct communication with Crestron’s RoomView Remote Asset
Management Software as well as with Ethernet enabled 2-Series 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 timestamp
logging. Data can be set to log every 1 to 60 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.
Rack Mountable
A heavy duty rack mount hardware kit is provided to mount the unit into any EIA
standard four 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.
