The PS 120/240 AC 50-U offers an impressive array of features that reduce or eliminate the
impact of power failure. A built-in battery charger in the PS 120/240 AC 50-U provides 15
watts maximum to the battery. The charger is current limited to prevent overloading the
power supply in the event of a shorted or defective battery. Using standard rechargeable lead
acid batteries, the PS 120/240 AC 50-U will provide 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 four hours; and
backup of DRAM and real-time clock for 72 hours duration. These backup modes can be
selected and controlled through Andover Controls

programming. Maximum
charging time of the battery charger is 48 hours using recommended batteries. (Two 12V
7.0 AHr sealed rechargeable batteries are included with the UPS model.) Extended
backup times are available using larger batteries.
The UPS circuit provides the
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 AC power
indicator LED. This option is ideal if you mount your
Continuum
system within a larger control
panel or enclosure and wish to verify power to the system from a separate location.
The PS 120/240 AC 50-U features a sleek, lightweight casing designed for natural convection
cooling. Built-in quick-release fasteners at the back of the power supply 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-sytle
Continuum
enclosure.

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
even to remote locations. Because there is no built-in battery charger in this model, a full 50 watts of power is
available.

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.
