30KW Resistive Load Bank For IEC 62040-3 UPS Test
Products Description
30KW Resistive Load Bank for IEC 62040-3 UPS Test
Equipment Overview:
This electric energy load testing device is easy to operate, small in size and convenient to transport. Depending on the load capacity, multiple units can be used in parallel. The control method is divided into manual button control.
Based on the requirements of IEC 62040-3 ED 2.0 2005 Annex C, figure C.1 and C.2, we have designed the load cabinet as following parts:
A set of resistive load, the resistive load is 30KW, the rated voltage is AC220V/60HZ, at the same time meet the single-phase AC127V/60HZ power supply test, the capacity can also reach 30KW.
Technical Parameters:
Power supply from test sample: If the power supply from the test sample is three phases, then all the GA, GB, GC and N terminals should be connected to test sample correspondingly (GA+GB+GC+N); if the power supply from the test sample is single phase, then one of the GA, GB, GC terminals plus N terminal should be connected to test sample correspondingly (such as GA+N terminals).
Power supply from mains: the power supply from mains should be three phases AC220V/60Hz, the power supply is for the control components of this load bank. Operator should remove the lower three wires from the lower three terminals, and wrap up them well. Then operator uses the power supply cord we’ve offered to connect to the mains (L1+L2+L3+PE). The load bank must be grounded reliably before use.
