Hebei Kaixiang Electrical Technology Co., Ltd

1. Main Functions<br />
(1) Load bank testing:It can test stable state three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, run duration of generating set and so on.<br />
(2)   Whether load/unload by manual control panel or by PC software control, user can pre-set the power then press the master load button.<br />
(3) Control mode: user can choose local manual control or intelligent control (PC control)<br />
(4) Local manual control: there is local control panel in load bank, with multi load steps, min load steps 1kW, controlled by buttons.<br />
(5) Intelligent control: user can control load bank by data processing software of PC to make automatic load/unload, display, record and manager the test data, form curve, graph and can be printed.<br />
(6) Control mode interlock: there is switch in control panel to choose control mode, other control mode is invalid if user choose one control mode.<br />
(7) LED multi-function meter display stable state three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, etc.<br />
 <br />
2. Data Processing Software Functions:<br />
(1) Communication type: through RS232, RS485 or USB interface.<br />
(2) Load mode: manual load or automatic load.<br />
(3) Manual load: input power and power factor.<br />
(4) Automatic load: User can set several periods of power and time, and in turn of 0%→25%→50%→75%→100% or 110%, etc preset order to make automatic load testing.<br />
(5) Parallel testing: when several load banks parallel working, parameters of each load bank can be displayed and recorded, so do the final parameters of paralleling working.<br />
(6) Real-time parameter: Current, voltage, power, power factor, frequency, time, etc could be displayed by software.<br />
(7) Safety monitoring: User can know the working conditions of load bank through software indicating light. When in abnormal stop protection, software will indicate the reasons of stopping.<br />
(8) Data collection interval: the min saving interval is 2 seconds.<br />
(9) Data saving and in query: testing data could be saved in software, user can query at any time.<br />
(10) Data display: it could display real-time data and history data; user can print voltage, current, frequency, power graphs and charts.<br />
(11) Charts and graphs are output in format of JPG while testing data output in Excel format, and all can be printed.<br />
