Consultar Alfa Network PD-1003 802.3af/at 12V PoE Module
[PD-1003]

PD-1003
802.3af/at 12V PoE Module

The PD-1003 module is designed to extract power from a conventional twice pair 1000M Ethernet or single pair 10/100M Ethernet cable. Let customer easily and flexible building in product design.

This designed can provide total power up to 30W as specified by the POE plus IEEE802.3at standard. In addition, The PD-1003 module can be interfaced to any PSE that follow detection and classification procedures defined by the IEEE802.3af/at standard

Compliant IEEE802.3af/at PD interface
Small SIL package size – 56.2mm (L) x 25mm (H)
Input voltage range 40V to 57V
Minimal (low cost) external components required
Short-circuit protection
1500V isolation (input to output)


Pin No. 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 -VDC DC Return. This pin is the return path for the +VDC output.
6 +VDC DC Output. This pin provides the regulated output from the DC/DC converter.

PD Signature
When the PD-1003 is connected to the Cat5e cable, it will automatically present a Powered Device (PD) signature to the Power Sourcing Equipment (PSE), when
requested. The equipment will then recognize that a powered device is connected to that line and supply power.

Isolation
To meet the safety isolation requirements of IEEE802.3af/at section 33.4.1 a Powered Device (PD) must pass the electrical strength test of IEC 60950 sub clause
This calls for either a) 1500Vac test or b) 1500V impulse test. The PD-1003 is specified to meet the 1500Vdc impulse test. It is also important that the tracks oneither side of the isolation barrier have at least a 3mm clearance.

DC/DC Converter
The PD-1003’s DC/DC converter provides a regulated low ripple and low noise output that has built-in short-circuit output protection.
