AC Load banks for sale
A comprehensive range of available AC load banks give the flexibility and reliable performance expected for the testing Generators and UPS systems.
The HAC415 range of load banks are offered from 5kW to 1200kW 3 phase, 380V to 690V, 50Hz or 60hz. The load banks are available with resistive, reactive or capacitive designs for unity phase or lead and lag load testing.
The outdoor designs for either portable or fixed installations can be supplied for 1kW switched load steps or to supply larger loading from 25% load step ratings of the generator.
Low cost automatic load regulation controllers are available to ensure the generator is sufficiently loaded in prime power applications.
Supplied with the option of trailer mounting, all units can be fitted with hand held remote controllers which can allow multiple units to be paralleled together.
The HAC240 range of load banks offer portable single phase 240V load banks which are small, lightweight and low cost. Ratings from 5kW to 14kW, allow testing for standard single phase UPS systems and generators.
Regular load bank testing of generators provides an essential health check service to prevent diesel engine failure due to wet stacking. Wet stacking occurs due to under loading of the genset which results in wet un-burned fuel building up in the engine. This fuel build up will over time line the combustion chamber cylinders and cause a reduction of the engines rating and efficiency which will ultimately cause premature failure of the generator. Running the generator on load of 50% - 100% of the genset rating will allow the engine to reach the recommend operating temperature, which will burn off the choke deposits. Hillstone and our partners can provide preventive maintenance programs.
Discharge testing is the approved method to determine the capacity of Lead acid and (Nickel Cadmium) Ni Cad/Ni Cd batteries, as recommended by all battery manufacturers such as Enersys, Exide, C&D Technologies, Hawker, Yuasa, Exide, Hoppecke, Saft, Varta, and in accordance to BS6290 part 4 / IEC TR 62060.
