Uninterruptible Power Supply
Crestron
CEN-UPS1250
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 also ensures a smooth changeover from primary power to a
backup generator.
Managed Power Control
The CEN-UPS1250 provides 12 120 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.
