TS1250 Crosswalk System Controller | Solar Powered Model | Traffic Safety Corp.
The actual maximum power output shall be specified in the sizing report.
The actual maximum power output shall be specified in the sizing report. The output flash pattern shall be selected by a set of output mode selector switches (1-4) located on the control card: 1-Same as primary; 2-In sync with primary, but non-enhanced; 3-Non-enhanced complement of primary; 4-Continuously on while primary is flashing. Notes: (a) Enhanced flash patterns cannot be used when operating in wig-wag mode. (b) Only one output mode switch can be on (closed) at a time for proper operation of the system.
c. The combined output power of the primary and secondary DC outputs shall be specified in the sizing report.
9. System Protection: Outputs A and B shall be protected by a replaceable fuse.
a. The modules shall consist of a minimum of 36 crystalline cells in series. Cells shall feature an anti-reflective coating and a low iron glass covering. Cells shall be encapsulated to protect them from the environment. Each module shall feature a weather tight junction box for connecting the array output cable to the module terminals. Power modules greater than 60 watts shall feature a minimum warranty of 15 years for power output. Modules, 20 to 50 watts, shall feature a minimum warranty of 5 years for power output. All modules shall feature an anodized aluminum frame for mechanical support.
b. Solar modules shall be able to be securely mounted to the top of a 4.5" O.D. pole assembly, or attached to larger diameter poles with a side pole mount structure that has been specifically designed to hold solar modules. All of the necessary hardware to install the modules to the mounts, and the mounts to the pole, shall be included in the bid. Security hardware for securing the module to the mount shall be included along with any special tools required for the hardware. Mounts made of steel will be powder coated or hot dip galvanized. Aluminum module mounts can be either powder coated or feature a mill finish.
a. The system shall come equipped with the number and type of batteries detailed in the sizing report. The battery type shall be a sealed, maintenance-free, valve-regulated design. The battery shall be a Gel or Absorbed Glass Mat (AGM) type, to suspend the electrolyte making it immobile.
b. Gel batteries using a thixotropic gel to suspend the electrolyte, shall also be considered an acceptable alternate.
c. Acceptable battery sizes that can be accommodated shall include either one or two batteries, up to group size 31.
a. Site information shall take into account average monthly solar insolation at a 45° tilt angle, average monthly temperature at the site, and latitude and longitude of the nearest city/town.
b. In the event that no data point exists for the given city/town where the installation will be done, sizing shall be prepared for the nearest data point available around the installation site featuring similar geographical and/or climatic conditions.
c. Load tabulation shall be included to detail the number, type and duty cycle of all loads in the system.
d. The report shall include the type of solar module to be used by model and manufacturer.
e. Type of battery shall be provided by model and brand name. Projected days of autonomy shall be provided with the battery information. The system shall support a minimum autonomy of 5 days, unless otherwise specified by the customer.
f. The worst case array to load ratio shall also be provided. Minimum acceptable array to load ratio for the solar system shall be 1.05 or greater in December when using the maximum power draw for the loads.
g. A system derating factor shall be included in the sizing report component sizing calculations to cover any losses from solar panel output mismatch, dirt/dust accumulation on panels, aging and losses due to system wiring. Losses may appear as a combined derating factor, but a thorough description of the sources of all losses accounted for shall be provided. Failure to provide a sizing report shall be considered non-responsive and result in disqualification, in which case the bid will be rejected.
14. Warranty: The crosswalk system controller shall be warranted against defects in workmanship and materials for one year from date of shipment and is eligible for TSC's 5-Year Limited System Warranty. Excluded from the TSC warranty are the solar array and battery. These components are covered under the warranty of their respective manufacturer.
