Resistive Load Banks


Load Banks

TUTCO manufactures BTU Load Banks to mimic the load that a power source will see in a wide-range of real-world applications and environments. Our load banks are used to test emergency back-up, UPS, inverters, turbines, production line testing, field testing, and all forms of on-site power. 

TUTCO open coil heating technology is at the heart of our resistive load bank. Our engineers address every requirement to ensure the longevity, stability, and safety of each unit. The accuracy of open coil elements can be to .01 ohms, AC or DC input power, 50/60 HZ, .5 to 600 Volts.  Load banks can used to test a large range Kilowatt levels from small loads to 100% of the KW rating required.
