Description

The BPI-7402 series of modules are designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af and IEEE 802.3at Power-over-Ethernet(PoE) standard.it is 30W POE PD Module ( Isolation Model),The BPI-7402 signature and control circuit provides the PoE compatibility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to 30W power to the port.

The DC/DC converter operates over a wide input voltage range and provides a regulatedoutput. The DC/DC converter also has built-in short-circuit output protection.

Features

  • IEEE802.3at and IEEE802.3af compliant
  • Maximum 30W output power
  • Input voltage range 36V to 57V
  • Integral high efficiency DC/DC converter.
  • Low output ripple and noise
  • High performance with low price
  • Short-circuit protection
  • Transformer isolation ,1000V isolation (input to output)
  • Easy to use, with a minimum number of external components.

Applications

  • IoT gateway
  • IP Cameras
  • Wireless access point
  • Security and alarm systems
  • VOIP telephone
  • Point of sale network terminal equipment

Pin Description

BPI-7402 at PoE module
Pin # Name Description
1 VA1 RX Input (1). This input pin is used in conjunction with VA2 and connects to the centre tap of the transformer connected to pins 1 & 2 of the RJ45 connector (RX) - it is not polarity sensitive.
2 VA2 TX Input (2). This input pin is used in conjunction with VA1 and connects to the centre tap of the transformer connected to pins 3 & 6 of the RJ45 connector (TX) - it is not polarity sensitive.
3 VB1 Direct Input (1). This input pin is used in conjunction with VB2 and connects to pin 4 & 5 of the RJ45 connector - it is not polarity sensitive.
4 VB2 Direct Input (2). This input pin is used in conjunction with VB1 and connects to pin 7 & 8 of the RJ45 connector - it is not polarity sensitive.
5 AT-DET+ Internal rectifier bridge output +
6 GND Internal GND
7 -VDC DC Return. This pin is the return path for the +VDC output.
8 -VDC DC Return. This pin is the return path for the +VDC output.
9 +VDC DC Output. This pin provides the regulated output from the DC/DC converter.
10 +VDC DC Output. This pin provides the regulated output from the DC/DC converter.
