- Description
- NASA/JSC has a requirement for: 1. Pre-programmable load sequencing available on each of the individual load channels with millisecond resolution. Both remote and local pre-programming options should be available. 2. Load sequence triggering options, including: a) detection of power supply voltage at the load terminals, b) communications based triggering (e.g., General Purpose Interface Bus (GPIB), RS-232, etc.), or c) a vendor specific triggering method. 3. Load operations in the following standard operating modes: a) constant resistance, b) constant power, c) constant voltage, and d) constant current. 4. General operations controllable from several industry-standard communications systems. These are USB, GPIB, RS-232, and analog voltage control, as well as front panel controls. 5. Compatibility with loads as high as 40 volts DC and power levels as high as 150 to 300 watts. NASA/JSC intends to purchase the Pre-programmable Electronic Load Bank based on a unique load sequence triggering capability. The trigger input that is offered is the unique feature that meets NASA?s most important immediate needs. This need has arisen based on the configuration of the CEV load system. This load system is to consist of several small loads (motors, solenoids, relays, etc.) which have not been fully developed at this time. The procured load banks are to be used to simulate the several loads in integrated power system evaluations. Each of the loads is to be capable of operating with a pre-programmed load profile simulating a particular load type. The method to be used to control the several simulated loads is to switch power to the loads through a load switching system from a common power supply. Each of the simulated loads is then to be triggered by detection of power supply voltage at the load terminals. Since there is a considerable number of loads that could potentially be included in the power systems testing that NASA is planning, it will be imperative that each load be triggerable with detection of power supply voltage at load terminals, and to therefore operate independently of a larger control and monitoring system. NASA power systems engineers have indicated that from 40 to 60 individual loads will be simulated with the load bank set that NASA is acquiring with this procurement. This capability will allow each of the load banks to operate independently of a larger control and monitoring system and will allow each of the load banks to begin a pre-programmed sequence of loads at the detection of load voltage application at the load terminal inputs through a simple relay contactor. NASA has determined that a system of independently-triggered, pre-programmed load banks is needed for its CEV power system testing. The Government intends to acquire a commercial item using FAR Part 12. Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on August 1, 2006. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
