Andover Continuum
Power Supplies with
or without UPS
The Andover ContinuumTM PS 120/240 AC 50-U, PS 120/240
AC 65-U and PS120/240 AC 85-U power supply modules are
designed to provide 24 VDC power for the Andover Continuum
NetController II CPU module and its associated Andover
Continuum I/O modules. In addition, these models provide full
UPS battery backup in the event of an AC line failure
.
Andover Continuum Power Supplies
with or without UPS Features
The PS 120/240 AC 50-U, AC 65-U,
and AC 85-U power supplies are part
of the Andover Continuum Ethernetbased intelligent building system. The
Andover Continuum system allows you
to cost-effectively mix and match DIN
rail-mounted CPU, power supply, and
various combinations of I/O modules and
user interfaces to meet your control and
monitoring needs.

All the models offer an impressive array of features
that reduce or eliminate the impact of power
failure. In them, a built-in battery charger provides
15 watts maximum to the battery. The charger’s
current is limited to prevent overloading the power
supply in the event of a shorted or defective
battery. Using standard rechargeable lead acid
batteries (not included), the 50-U model will provide
full UPS operation including all I/O modules for up
to 60 minutes at 35 watts power consumption;
the 65-U model provides 60 minutes full UPS at
50 watts; the 85-U model provides 30 minutes full
UPS at 70 watts. Both allow for full operation of the
CPU module only (including modem and network
interface) with no I/O power for four hours; or
backup of DRAM and real-time clock for 72 hours
duration.
These backup modes can be selected and
controlled through Andover Plain English™
programming. Maximum charging time of the
battery charger is 48 hours using recommended
batteries. Two 12V 7.0 AHr sealed rechargeable
batteries are required with both models (not
included). Extended backup times are available
using larger batteries.

The UPS circuit provides the Andover Continuum
CPU with two status signals indicating the
operating condition of the power supply — one
signal indicates an AC power failure and a
change over to UPS mode and the other signal
indicates when the battery voltage has reached
an unsafe discharge level and will soon shutdown.
A disconnect switch removes the battery and
prevents further discharge of the battery.

A connector located on the bottom of the power
supply is provided for an optional Main Power
indicator LED. This option is ideal if you mount your
Andover Continuum system within a larger control
panel or enclosure and wish to verify power to the
system from a separate location.
The power supply module features a sleek,
lightweight casing designed for natural convection
cooling. Built-in quick-release fasteners at the back
of the module are provided for DIN rail mounting —
no tools required. These fasteners also snap into
a locked position for panel mounting. The power
supply is designed for mounting in an optional
NEMA 1-style Andover Continuum enclosure.
Other Available Models
PS 120/240 AC 85
A non-UPS version, the PS 120/240 AC 85, is also
available. This power supply can also be used as
an extended power source to power additional
I/O modules directly, extending the capabilities
of a typical Andover Continuum system, even to
remote locations. Because there is no built-in
battery charger in this model, a full 85 watts of
power is available.
PS 120/240 AC 65
A non-UPS version, the PS 120/240 AC 65, is also
available. This power supply can also be used as
an extended power source to power additional
I/O modules directly, extending the capabilities
of a typical Andover Continuum system, even
to remote locations. Because there is no built-in
battery charger in this model, a full 65 watts of
power is available.

PS 120/240 AC 50
A non-UPS version, the PS 120/240 AC 50, is also
available. This power supply can also be used as
an extended power source to power additional
I/O modules directly, extending the capabilities
of a typical Andover Continuum system, even
to remote locations. Because there is no built-in
battery charger in this model, a full 50 watts of
power is available.
PS –48 DC 50
A PS –48 DC 50 model is available. This model
accepts power from –41 to –53 VDC and allows
industries such as telecommunications to provide
uninterrupted power to critical environmental
monitoring and control equipment using their own
battery-backed power systems.
