Hebei Kaixiang Electrical Technology Co., Ltd

Introduction<br />
Portable AC Variable Load Bank can accurately test output power and load capacity with all kinds of generators, generator sets for all main electrical parameters including the dynamic parameters tested. <br />
Measuring Control Function<br />
--Load testing: load power that not beyond the rated power, testing and display stable state 3 phases voltage, current, active power, frequency, working time, etc of generator sets.<br />
--Load/unload with one key: Whether manual control, remote control or software control, user can preset the power, then press load master button. Load bank loaded according to preset power to avoid load fluctuation during the power changing.<br />
--Control Pattern: user can choose local control, remote control and intelligent control.<br />
--Local Control: There is local control panel with several power steps; user can load/unload by button.<br />
--Remote Control: Control through remote control box.<br />
--Intelligent Control: Through data processing software in PC, user can make automatic load, to display, record and manage the testing data, to form curves, tables, also to print them.<br />
--Control Pattern interlock, there is control pattern switch, when choose one control pattern, operation of other pattern is invalid, avoid the clash.<br />
--Local meter display data: local meter can display 3 phases voltage, current, active power, frequency and so on.<br />
