Resistor Load Banks High Current Oval Edgewound The choice when conditions demand top-notch performance, these resistor load banks are commonly used for dynamic braking on Transit applications or where high current handling and wattage are required. Ohmite's unique Oval Edgewound design allows for more wattage in smaller a package. Choose from four bank wattages with up to thirtyone current ratings per bank. Built to perform in rugged environments, Ohmite load banks feature corrosion resistant stainless steel insulator supports, solid nickel terminals, and special electroless nickel-plated solid copper terminal supports. The resistance element is made of a stainless steel resistance alloy. Terminals are welded or silver brazed to the oval, spiral edgewound resistance element. Toothed ceramic insulators isolate the resistance element from the center support. Ceramic end bushings insulate the center support from the mountings. characteristics Current Rating Continuous duty as listed below. Wattage Rating Continuous duty based on a 375°C temperature rise. Working Voltage Limited to 1000 Volts if mounting is grounded. Special higher voltage mounting is available. Resistance ±10%. Tolerance Terminals/Jumpers Standard terminals have 5/16 stainless hardware for ring lug connections. Brass tags can be placed at connection points for identification. If necessary, all connections can be made on one side of grid. Fixed tap terminals are also available. Jumpers between resistors are nickel plated solid copper. Mounting Resistor Banks can be produced in grid arrays of 2 x 4 to 4 x 4. All resistors in one grid are the same length. Frames are constructed of heavy gauge zinc plated steel. Either “bolt up” or “bolt down” type frames are available. Frames may be grounded if voltage potential is below 1000 Volts. 8KW 12KW 15KW 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • [email protected] NOTE Load banks require significant investment in resistance wire due to high minimum order quantities imposed by our vendors. Before ordering always check with the factory on wire availability. 24KW Resistor Load Banks High Current Oval Edgewound dimensions W H 0.31 19.57 1.75 A Type A H W 8KW 16.50 12.69 18.25 12KW 15KW 18.28 24KW 16.50 18.81 16.50 18.25 24.94 19.88 18.25 24.94 21.63 Dimensions for reference only; Consult factory for details. 0.56 0.63 o r d e r i n g i n f o r m at i o n HCLB-12-R165E Series High Current Load Bank Wattage Resistance 8K, 12K, 15K, 24K RoHS Compliant 8K Watt 12K Watt 15K Watt Resistance Current Wattage Resistance Current Wattage Resistance Current Wattage Resistance Current Wattage 0.099 0.122 0.144 0.165 0.248 0.284 0.286 0.333 0.360 0.383 0.412 0.418 0.482 0.562 0.576 285 257 236 221 180 168 167 155 149 145 140 139 129 120 118 0.659 0.680 0.711 0.770 0.833 110 109 106 102 98 1.636 1.701 1.920 1.944 2.246 70 69 65 64 60 0.878 1.145 1.215 1.373 1.534 2.448 3.168 4.091 6.120 11.025 96 84 81 76 72 57 50 44 36 27 8,041 8,049 8,020 8,044 8,019 8,027 7,982 8,000 7,992 8,061 8,070 8,068 8,013 8,087 8,020 7,971 8,084 7,989 8,015 7,995 8,095 8,078 7,972 7,928 7,950 8,017 8,098 8,112 7,963 8,087 7,954 7,920 7,919 7,932 8,037 0.165 0.203 0.240 0.275 0.321 0.366 0.474 0.495 0.555 0.609 270 244 224 210 194 181 159 156 147 140 0.660 0.720 0.810 0.915 0.960 135 129 122 115 112 2.220 2.430 2.745 3.240 3.660 73 70 66 61 57 1.134 1.320 1.464 1.665 1.896 3.744 3.960 4.080 5.280 7.350 8.181 12.240 16.320 22.050 103 96 90 85 80 57 55 54 48 40 38 31 27 23.5 12,029 12,092 12,042 12,105 12,081 11,991 11,983 12,046 11,993 11,942 0.220 0.271 0.320 0.366 0.428 0.488 0.550 0.632 0.740 0.800 24K Watt 261 236 217 203 187 175 165 154 142 137 14,987 15,082 15,068 15,082 14,967 14,945 14,974 14,989 14,921 15,015 14,819 14,897 14,985 15,029 14,848 12,029 11,982 12,056 12,101 12,042 0.880 0.928 1.070 1.220 1.280 130 127 118 111 108 14,872 14,968 14,899 15,032 14,930 11,830 11,907 11,957 12,056 11,891 2.544 2.700 2.960 3.050 3.120 77 74 71 70 69 15,083 14,785 14,921 14,945 14,854 12,031 12,165 11,858 12,030 12,134 12,164 11,979 11,897 12,165 11,760 11,813 11,763 11,897 12,177 1.512 1.760 1.850 2.130 2.320 3.780 4.320 4.400 4.880 5.440 7.040 9.090 9.800 13.600 21.760 24.500 99 92 90 84 80 63 59 58 55 52 46 41 39 33 26 24.5 15,003 15,038 14,802 14,762 14,710 14,897 15,280 14,906 14,810 14,710 14,706 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • [email protected] 0.328 0.82 0.976 1.112 1.312 271 171 157 147 135 24,089 23,978 24,057 24,029 23,911 1.344 1.416 1.904 2.272 2.292 133 130 112 102 102 23,774 23,930 23,884 23,638 23,846 4.448 4.76 5.376 5.664 5.68 73 71 67 65 65 23,703 23,995 24,133 23,930 23,998 2.44 2.78 3.36 3.54 3.904 5.73 7 7.616 9.088 9.168 10.32 17.5 25.8 28 41.28 99 93 84 82 78 64.5 58 56 51 51 48 37 30.5 29 24 23,914 24,044 23,708 23,803 23,752 23,838 23,548 23,884 23,638 23,846 23,777 23,958 24,000 23,548 23,777
