Perpetual Power Unit (PPU)
The PPU solves a common problem within the security industry
by allowing light poles with timed power to be used to power
security equipment 24/7 without outages. Light poles in parking
lots and along streets make great places for security cameras,
but unfortunately are often on centrally controlled timers which
cannot be changed. During the day when it is light outside, the power
is off. Since it is imperative that security equipment such as cameras
and communication devices operate continuously, the poles which
are potentially great assets are often not used for security
locations since the costly burden of trenching a separate power
line to the pole is typically cost prohibitive. The PPU is a
cost effective solution that allows pole assets to be used
by quickly charging a deep cycle battery when AC power is
available, and in turn supplying 12V DC to the loads on a
continuous basis.
The PPU is quite different from an outdoor UPS in that typically a UPS
can only supply power to security devices such as cameras and
communications equipment for 1 or 2 hours, while the PPU can handle
much longer times. Depending on the load and PPU model, the PPU can
continuously power loads for days. For this reason, even when power is
always available at a site, the PPU is often used as an ultra UPS,
capable of handling extended outages without the security
devices going off line.
In addition to providing clean continuous power to the security loads
day after day, the PPU contains an intelligent control mechanism. This
mechanism can be used to monitor loads and automatically or manually
reset them if needed, report unexpected power outages, precisely adjust
charging voltage based on temperature, and other similar tasks.
Features
- Intelligent power system
- Allows timed power light poles (on at night) to be used as 24/7 camera locations
- Provides clean continuous power (12V DC) to loads for long periods of time
- Saves money by eliminating costly trenching
- Intelligent controller can cycle load power to reset loads often saving a site visit
- Browser based, no software to install. Accessable by any browser capable device
- Unlike solar, very dependable since timed power is dependable
- Can be used as an ultra UPS to prevent security system down time
- Lockable UL Nema 3R vented enclosure
- Two PPU models: PPU-1 104Ah, PPU-2 208Ah
A single PPU normally can provide plenty of power for the typical set of security devices deployed on a pole (1 or 2 cameras and communications device). In cases where the security loads consist of many devices or devices that consume more power than is typical, two PPUs can be used together to provide consistent continuous power. Alternatively, if charge time is adequate, a single PPU-2 may suffice for high power consumption sites.
