 Measuring Control Function

--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.

--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.

--Control Pattern: user can choose local control and intelligent control.

--Local Control: There is local control panel with several power steps; user can load/unload by button.

--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.

--Control Pattern interlock, there is control pattern switch, when choose one control pattern, operation of other pattern is invalid, avoid the clash.

--Local meter display data: local meter can display 3 phases voltage, current, active power, frequency and so on.

 

 Software Function

-- Communication type: through RS232, RS485 or USB interface.

-- Load mode: manual load or automatic load

-- Manual load: input power and power factor.

-- Automatic load: User can set several periods of power and duration and in turn of 0%→25%→50%→75%→100% or 110%, etc to make automatic load testing.

-- 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.

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

-- 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.

-- Data collection interval: the min saving interval is 2 seconds.

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

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

--Data format: Charts and graphs are output in format of JPG while testing data output in Excel format, and all can be printed.

 

 Protection

--Emergency stop: you can press the Emergency Stop switch in the panel, when the load bank is locked in this state, it cannot add any load.  

--Overvoltage protection: when input voltage is over the safe value, it can unload automatically and give an alarm.

--Short circuit protection: when short circuit, fuses in the load bank can insure to unload automatically.

--Overheating protection: when temperature is over the safe value, it can unload automatically and give an alarm.

--Fan interlock protection: load bank cannot add any load when working power of fan is off.

--Protection Buttons: There are buttons for some protection, when misinformation occurs or user has special needs, user can temporarily turn off the corresponding protection function.

--Phase sequence protection of fans: 3phase fans still running although there is a wrong phase connect of control power.

--Chassis Ground Protection: in order to avoid the danger of electric shock when operating, the load bank is equipped with special ground protection terminal.
