AC400V-1250kvA Adjustable Load Bank With Frequency 60 HZ In High Performance
Introduction
Adjustable Load banks can be supplied for most powers, voltages, frequencies and sizes. Multi-voltage load banks are also available for operation over a large voltage range. At the same time, It can operate in parallel with more than two units.
AC400V-1250kvA Adjustable Load Bank can simulate the real working conditions and provides a rigorous test regime for power supplies from 1kW to 60MW. Resistive, inductive(reactive),capacitive or combined load banks can be customised for any application.
Triumph load are available in stationary type for permanent installation or portable type with fork lift pocket base, castors. Larger load banks, typically above 1200kVA, are based on an ISO container construction. Special finishes including custom paint colors and stainless steel casings can be supplied.
Application
1. factory testing of engine generator sets
2. To reducewet stacking problems
3. Periodic excercising of stand-by engine generator sets
4. Ups system testing
5. Battery system testing
6.Load optimization in prime power applications
7. Factory testing of turbines
