There is a trend in the locking hardware industry towards lower power locking devices. From
ortise locks to electric strikes and exit
devices, companies have been migrating
from high powered solenoid actuators to
lower powered options. For example the
EcoFlex™ electrified mortise lock
from ASSA ABLOY Group brands Corbin
Russwin and SARGENT takes what used
to be a 500mA current draw and reduces
it to a mere 15mA. This 96% reduction in
the lock’s power consumption is a huge
improvement over existing locking devices.
However, as more people move toward
low-power locking devices, they overlook
what has become now the door’s main
source of power consumption… the power
supply that is sitting back in the IDF closet.
Even when you have no power consumption
from a fail-secure lock, the power supply is
drawing 5+ Watts of power from the wall
24 hours a day, 7 days a week; providing
exactly zero benefit to the end user. Enter
EcoPower™. Using technology similar to
a plug-in electric car, EcoPower utilizes
the included battery to provide power to
the locking device while maintaining 24+
hours of battery backup in the event of
a power failure. While the battery “drives
the lock” the power supply enters a sleep
mode drawing a mere 0.008W from the
wall, a GreenCircle Certified* 99% re-
duction even when compared to highly
efficient switching power supplies. When
the battery reaches about 50% of its usable
capacity, EcoPower wakes up, recharges
the battery, and then goes back to sleep.
During this recharge phase, EcoPower
draws only 2W from the wall - significantly
less than a traditional power supply draws,
even without powering a locking device.
What happens when the battery reaches
its end of life? EcoPower is designed with
a microprocessor on board that detects
when the battery is at the end of its life
and notifies the end user that it is time for
a battery replacement. If the battery is
removed, EcoPower is still a fully functional
power supply capable of powering both
the low powered lock and card reader,
even in the absence of the battery.
The only thing that is lost is the ability
to go to sleep in a Fail-Secure
application where the lock is powered
continuously. However, EcoPower still
provides over a 70% reduction in power
consumption even in this scenario. In a
Fail-Safe scenario, while the lock is
unpowered, EcoPower will continue to
enter sleep mode and reduce power
consumption significantly.
Whether you are working on a net-zero
energy building, or simply a building
where the end user cares about dollars
and cents; EcoPower when paired with
a low power locking device such as the
EcoFlex mortise lock from ASSA ABLOY
can reduce total door power consumption
by 99% when compared to the
traditional solenoid based alternatives.
The best part? This savings can be
achieved with zero extra out of pocket cost
to the end user. Every k Wh saved is money
in the end users pocket.
Think cutting edge.
Think EcoPower.
