Product Detail
Introduction
AN8721P(F)/AN8711P(F) AC/DC power meter adopts ARM7 series controller as the core,using direct sampling and intellignet indentification technology,widely used for single-phase electrical equipments test,such as voltage,current,power,power factor,frequency,electric energy,time etc,Highlighted LED 3-window display ,simple and fast operation,serial communication,over limit alarm,voltage/current ratio setings and other functions,prcise and durable.
Main features
* Beautiful appearance,compact dimensions,low weight;
* Fast measurement speed,up to 200ms refresh rate;
* Voltage/current ratio can be set to expand measuring range;
* Sound & light alarm for voltage/current/power over limit,satisfy fast identification of defected products on production line;
* Minimum current measurement range is low to 0.4mA,meet the test requirement of standby power consumption;
* Wide AC/DC range,suitable for various load;
* RS-232/RS-485 port to realize automatic testing and data transmission;
* Optional I/O prot to realize remote control signal iput and alarm signal output
Functions
* Parameter sttings:voltage/current ratio,integral threshold current,electric energy accrmulating time,voltage upper/lower limti,current upper/lower limit,power upper/lower limits,alarm delay time,address,baud rate,buzzer On/Off,calculation mode and other parameters can be set,and preset parameters will be memored;
* Over limit alarm;sound & light alarm as certain parameter is out if the preset range,giving sound & light alarm signal automatically and output the digital signal(optional);
* Swithc of range:manual set to range,or power meter will automatically switch to a proper rangge under Auto range mode;
* Accumulating Time:electric energy accumulating time can be set;
* Engrgy accumulation:display the accumulated electric energy within the preset time;
* Ratio settings:voltage/current ratios can be set based on the actual measurement and the ratio of primary and secondary of external transformer,easy expansion;
* Serial communication:test results can be collected via RS-232 or RS-485(optional)on computer.
