822 PS - 1200 Watts Battery Backup for Sump Pumps by SEC America

Description

Product Description
822PS Pump Sentry
interfaces between a pump and its AC wall outlet. When AC utility power is present, the 822PS charges a battery and monitors the wall outlet to detect a power outage. At the moment utility power fails, the 822PS draws energy from a battery and converts it to enable pump operation. When utility power returns, the 822PS automatically switches the pump back to AC wall outlet power. At the same time, the 1612PS resumes charging the battery to return it to full capacity in preparation for the next power failure.
When electricity is available, Pump Sentry charges a battery and monitors the power line to detect a power outage. At the instant that power failure occurs, Pump Sentry draws the energy stored in the battery and converts it to AC power. This AC power is automatically channeled to the pump to maintain its operation in the absence of electricity.
How to Calculate Operating Time During Power Outage
Operating time will depend on the following:
a) The size of the battery bank i.e. its total Ampere-Hour (A-hr) capacity
Ampere-Hour capacity is calculated by adding the A-hr ratings of
all the batteries in the battery bank where the batteries are connected in parallel.
(For Parallel Connection See Fig. #1)
b) The current draw for the pump in Amps (C).
This can be read off the nameplate on the sump pump
c) The average operating duty cycle of the system
The duty cycle of a system is the ratio of its "on" time to its "on" time plus "off" time
e.g. if a pump will work for 10 seconds and is then off for two minutes (120 seconds)
its duty cycle is calculated as follows:
Duty cycle = 10/(10+120) = 0.077
Once (a) (b) and (c) are known the operating time of a pump sentry
in hours can be calculated by the formula:
T = A-hr/(C x 10 x D)
e.g. for a system with 1 battery rated 90 A-hr.
1) 1 battery rated 90 A-hr., A-hr = 1 x 90
2) A sump pump that draws 9 Amps, C=9
3) Duty cycle which operates 10 seconds "on" followed by
3 minutes (180 seconds) "off", D = 10/(10+180) = 0.053
T (Hours) = (1x 90)/(9 x 10 x 0.053) = 19
In 10 seconds the average 1/3 hp. sump pump will
evacuate approximately 10 gallons of water.
