Load banks are simulating load test equipment used for generators, UPS, battery banks and more. Resistive load banks are used to mimic the load your generator or power equipment will produce when in real application. Resistive load banks are used in many industries in order to protect generators and equipment alike, ensuring they will operate optimally. Blue Diamonds range of load banks are designed and built for continuous operations in the harshest outdoor environments, operating safely and reliably in ambient temperatures of 50 degrees and above.
