- Item: 0001NSN: NSL, RADIATOR MOUNTED LOAD BANK Description: Contractor shall provide a radiator mounted load bank for the AN/TRN-26C Generator IAW description below.Total Line Item Qty: 40.0000 1. GENERATOR LOAD BANK DESCRIPTION 1.1 General: An engine radiator airflow cooled, resistive Load Bank is required for permanent, on site installation as a component of a engine generator system. 1.2 Installation: The Load Bank shall be installed within the air outflow of the engine unit mounted radiator and shall be cooled by the radiator airflow. The Load Bank may be installed by one of the following methods: 1.2.1 Bolted attachment to radiator the load bank will mount to the exterior of the generator housing. The radiator opening (of the generator housing) measures 16 1/4" w x 15 3/16" h.; The Load Bank shall be weatherproof designed for installation and operation OUTDOORS. 1.3 Electrical Connection: Power source to Load Bank connection is 3-phase, 3-wire plus ground. Additional control wire connections for remote control as required. 1.4 Load Bank Rating: 1.4.1 Capacity: 10 KW. 1.4.2 Load Steps: Nominal 20% of load bank KW(10, 20, 25, 40, 50) KW load step resolution 1.4.3 Voltage: 240 Volts AC, 1 Phase, 1.4.4 Frequency: (60) Hertz 1.4.5 Air intake temperature: 155F max (radiator air outflow) 1.4.6 Airflow requirements: Radiator air outflow 1.4.7 Duty Cycle: Continuous 1.4.8 Air temp. rise: 100F, nominal 1.4.9 Air back pressure:.25-.50" water column 1.5 Load Bank Design 1.5.1 General: The Load Bank shall be a completely self-contained unit which includes all resistive load elements, load control devices, load element branch circuit fuse protection, main load bus and terminals, control terminals, system protection devices and NEMA enclosure of required type. The weight of the load bank will be a significant factor. 1.5.2 The Load Bank shall be the manufacturer's standard product that has been investigated, tested andlisted by Underwriters Laboratories as a system for the purpose intended. Simple assemblies of listed parts that are not system UL listed shall not be acceptable. 1.7 Warranty: The Load Bank shall be supplied with a 2-year manufacturer's warranty which covers all materials and service labor. The manufacturer shall demonstrate the availability of factory service technicians in support of the Load Bank. 1.8 Start-up Service: The Load Bank manufacturer is will participate in all first article testing/kit-proofing of the Load Bank, on site, location and times TBD. 1.9 Qualifications of Load Bank Manufacturer 1.9.1 The Load Bank shall be a product of a firm regularly engaged in the design and manufacture of generator Load Banks. 1.9.2 The Load Bank manufacturer shall demonstrate at least five years experience with at least twenty-five successful installations of Load Banks similar or equal to the Load Bank specified herein. 1.10 Automatic Load Bank Controller 1.10.1 The Load Bank is to be equipped with an automatic controller which will be activated when the Load Bank mode control selector switch is placed in the "automatic" position. 1.10.2 In automatic mode, the Load Bank is to be on-line and continuously operative whenever the power source runs. The Load Bank shall provide a component of the total power source load and shall be automatically variable in response to dynamic total load demands upon the power source. 1.10.3 The automatic controller shall include control logic, solid-state sensors and time delays which shall act to apply/remove Load Bank component in multiple steps in response to dynamic output of the power source. 1.10.4 The automatic controller shall function to maintain total load upon the power source within a preset bandwidth by adding Load Bank load component as external load component drops and removing Load Bank component as external load rises. 1.10.5 The automatic controller shall sense load (amperes, kilowatts). 1.10.6 Full manual control of the Load Bank shall be restored when the mode selector switch is placed in the "manual" position. 1.10.7 The automatic controller shall include a solid-state load sensor with level and time delay adjustment and output contacts Destn:,,TBD.,00000. Delivery: 120 DARO, 40.00 Electronic procedure will be used for this solicitation. See Note(s) 25 and 26.
