Small appearance easy to understand operation; several types available to meet different customer needs Only need to be connection in series to the positive terminals of the circuit, no need to the negative terminals. No input Voltages limitation. (Guaranteed reverse Voltages belows 40V) 300A high current tube, tube can pass 40A current, 1 milliohm on-resistance, small loss, low heat generation. Fast response to reverse polarity within 2US, input and output equivalent to diode. Detect the output Voltages is greater than the input immediately shut down the output, detection value of millivolt level, the corresponding speed is very fast Model: LXD40100 40A No Voltages Limitation Diode Module Size: about 50x33x18mm/1.97x1.3x0.7in (with terminals); 50x33x4mm/1.97x1.3x0.16in (without terminals) Working environment temperature:-40-125 degree Component: PCBA Functions: 1.Replacement of ordinary high current diode, storage batteries, solared panel, reverse flooding and reverse current resistant. 2. Series connection in the input of the power supply is for reverse poofed connection Precautions: The input Voltages is unlimitedly, but there reverse Voltages requirements, the reverse Voltages is lower than 40V, the output Voltages can not be than the input Voltages of 40V, for example: the input is connection to the 24V power supply, the output is connection to the battery, can be connection to the 12V, 24V 36V 48 60V battery, can not be connection to the battery above 72V, (72V output 24V input =48Voltes) the reverse Voltages is than 40V.
