1500KVA Resistive Inductive AC Variable Load Bank

(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.

(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.

(3) Control mode: user can choose local manual control or intelligent control (PC control)

(4) Local manual control: there is local control panel in load bank, with multi load steps, min load steps 1kW, controlled by buttons.

(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.

(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.

(7) LED multi-function meter display stable state three-phase voltage, current, active power, reactive power, apparent power, power factor, frequency, etc.

Data Processing Software Functions:

(1) Communication type: through RS232, RS485 or USB interface.

(2) Load mode: manual load or automatic load.

(3) Manual load: input power and power factor.

(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.

(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.

(6) Real-time parameter: Current, voltage, power, power factor, frequency, time, etc could be displayed by software.

(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.

(8) Data collection interval: the min saving interval is 2 seconds.

(9) Data saving and in query: testing data could be saved in software, user can query at any time.

(10) Data display: it could display real-time data and history data; user can print voltage, current, frequency, power graphs and charts.

(11) Charts and graphs are output in format of JPG while testing data output in Excel format, and all can be printed.
