Product Description

 High current 300A / 500A digital detection module current sensing switch with alarm output transformer

pls note: this price is for 0-300a, if you need 0-500a ones, it need to add 15usd

 

Product Features

  Designed for high-current detector design eliminates the need to set parameters, direct use, extreme simplicity   Isolation transformer sampling, safe and convenient   300A and 500A current component detected two kinds   Digital display present current value   Two Alarm relay and transistor output options   Rail mounting and screw mounting optional   Small, good for installation   Selection NOTE:   Case relay alarm outputs can be connected to AC and DC current is relatively large, but not suitable for use in the frequent, fast-off case   Case transistor alarm output terminal can only be connected DC, and the current is small, usually only use alarm signal can not be a large load in series, but for frequent, fast-off.   Performance parameters:   1, the current measuring range: AC 50--60HZ maximum 500A   2, the power supply voltage: DC 6-30V   3. Display: 4 digital display, display accuracy 0.1A   4. Alarm: transistor or relay outputs   5, alarm current value: user demands, the factory curing process   6, pore size: 26mm   Interface Description   Current detection module has three interfaces, namely power connector, alarm output interface, the CT interface.   Power Interface: There are positive and negative points, module hardware with anti-reverse, over voltage, short circuit protection.   Alarm Interface: relay output nonpolar     Transistor output polarity   CT interface: no polarity.   Precautions   1, the transformer can not use open, in front of the transformer feedthrough current electricity, please transformer connected to the measurement module interface.   2, set the interface tighten the screws, make sure the wiring is good. When found to have feedthrough current transformer, and the display is still 0.0A, please check the cable is normal.   3, where there are polar interface, have to pay attention to the polarity when connecting.         The shop in the premise of guaranteeing quality, provide the highest price.
