Power Supplies: Securitron Goes Off the Grid

Jan. 31, 2011

Alternative energy seems to be a popular topic of discussion these days, with the final verdict of its feasibility up for extended debate. Primary concerns about alternative energy sources relate to cost-effectiveness and functionality. Solar energy has already established itself as a viable alternative in a variety of applications.

In some more conventional situations, part of an assessment of feasiblilty might involve payback on the investment. That is, how long will it take for a particular energy alternative system need to operate before the benefits have amortized the investment. Tied into this math is the comparative cost of the non-alternative being supplanted. Also consider any additional maintenance costs which the alternative might incur and which would skew the cost-vs-benefits assessment.

In physical security other variables can be introduced. A significant issue is the risk assessment of the site, and the relative benefits of having some form of smart security as opposed to having none at all.

We can all probably agree that an electronic access control solution trumps a conventional key solution. We can provide unique PINs for each individual who will be authorized for access to the site. We can easily add or remove PINs without expensive re-keying.

What about remote sites where security is required but line voltage is not available?

Securitron's Boxed Power Supply – Solar (BPSS) is capable of powering most any single point access control device and fail-secure lock (intermittent duty only) using sustainable solar and battery operated power. The BPSS is specifically designed for remote electric lock control. Select the BPSS-10 or BPSS-20 (10 or 20 charging Watts respectively) based on the solar activity in the area/region where installed.

Product Features

  • Remote electronic locking of gates and out buildings
  • Works with most fail-secure electric locks
  • Works with most keypad or card readers
  • Available in 10W and 20W versions
  • Outdoor Operation
  • 100% Solid State Solar Controller
  • Low voltage battery monitor to protect batteries from deep discharge
  • Includes mounting brackets for power supply enclosure and solar panel
  • Optional brackets to mount power supply enclosure to 3" diameter pole

Optional solar wind kit for high wind areas

Enclosure dimensions are: Outdoor 12-1/2" x 13-5/8" x 4-7/16". Standard enclosure brackets accommodate up to 2" diameter pole/post.

The operating temperature range is -4 to +113 degrees Fahrenheit (-20 to +45 degrees Centigrade.

Power Supply Output: Maximum 125mA continuous; 450mA maximum operating the locking device - intermittent duty only. Number of daily lock operations will vary due to solar activity and current draw.

Solar panels are high-efficiency photovoltaic modules using silicon nitride multicrystalline cells. BPSS-10 dimensions are 14.5" x 12.2" x .7" and weigh 3.3 pounds. BPSS-20 dimensions are 22" x 14.2" x .7" and weigh 5.5 pounds.

The controller is enclosed in an anodized aluminum case with marine rated terminals. It is approved for use in hazardous locations - Class 1, Division 2, Groups A, B, C, D.

Voltage Output is 14.4VDC maximum and it the unit carries the SecuriCare 3 Year No Fault Warranty.

Q & A: Mark McBroom

Locksmith Ledger once again prevailed upon Mark McBroom, Securitron’s product manager, to fill in some of the blanks about the BPSS. Following are Ledger’s questions and his answers.

How many “Off-The-Grid” products does Securitron offer?

Securitron currently only offers the BPSS power line of solar power supplies

Which market segment do these products target?

Typically the gate and fence market.

Can you determine where the existing demand is for this product?

Perimeter fencing, remote out-buildings, communication towers, any remote facility.

How does a security professional know which product is appropriate for his application/ geographic?

Securitron has several solar calculation tools available on our web site, www.securitron.com

Are there special tools required for set-up?

Nothing special is needed other than a compass.

What would comprise a typical deployment?

Typical installations include the BPSS, GL1 gate lock and the DK-25 keypad (any access control device drawing less than 100mA will generally work)

Are any other Off-The-Grid products forthcoming?

We are looking into expanding our gate and fence line with solar friendly products in the near future.

Is there a preferred standalone access controller?

The DK-16 or DK-26 is Securitron’s recommendation, but any controller that draws less than 125mA continuous power and 450mA when operating the fail secure lock ( lock power included)
