Power Module Characteristics
The following table lists the features included in the Continuum Power Supply Modules:
Model Input Voltage Power Output Features
PS 120/240 AC 50* 120-240 VAC 50 W
PS 120/240 AC 50-U* †120-240 VAC 35 W UPS
PS 120/240 AC 85* 120-240 VAC 85 W
PS 120/240 AC 85-U* †120-240 VAC 70 W UPS
PS –48 DC 50* -48 VDC 50 W DC Input
PS 120/240 AC 25 120-240 VAC 5V @25 W
PS 120/240 AC 50-U, PS 120/240 AC 85-U
These Continuum power modules provide 35 and 70 Watts (respectively) of power
for the CPU and I/O modules. They contain features that reduce or eliminate the
impact of power failure. An external 24 VDC battery source may be connected to
provide un-interruptible power. A built-in battery charger assures the battery is
charged at all times. This circuitry consumes 15 Watts of the initial power available.
Using standard rechargeable lead acid batteries, this unit provides full UPS operation
including all I/O modules for up to 60 minutes at 35 watts power consumption; full
operation of the CPU module only (including modem and network interface) with no
I/O power for 4 hours; or backup of DRAM and real-time clock only for 72 hours
duration. These backup modes are selected and controlled through Andover Controls
Plain English
®programming language.
PS 120/240 AC 50, PS 120/240 AC 85
These power supplies are non-UPS versions of the above listed modules. They
supply a full 50 and 85 Watts (respectively) of power and can also be used as
auxiliary power sources to power additional I/O modules directly, extending the
capabilities of a typical
Continuum
system, even to remote locations.
PS –48 DC 50
This model accepts a –48 VDC input voltage that allows industries such as
telecommunications to provide uninterrupted power to critical environmental
monitoring and control equipment using their own battery-backed power systems.
PS 120/240 AC 25
This power supply provides a +5VDC output at 25 Watts of power and is used as a
external power source to power third party devices and sensors.
* These units are listed for use in UL 294 applications. †These units are listed for UL 1076
