PULS POE.8AT-DC1 POE Power Supply

INTRODUCTION

Before operating this device, please read this manual thoroughly and retain this manual for future reference! This device may only be installed and put into operation by qualified personnel. If damage or malfunction should occur during operation, immediately turn power off and send device to the factory for inspection. The device does not contain serviceable parts. The information presented in this document is believed to be accurate and reliable and may change without notice. For any clarifications the English translation will be used.

WARNING Risk of electrical shock, fire, personal injury, or death:

Turn power off before working on the device. Protect against inadvertent re-powering.
Do not open, modify or repair the device.
Use caution to prevent any foreign objects from entering the housing.
Do not use in wet locations or in areas where moisture or condensation can be expected.
Do not touch during power-on and immediately after power-off. Hot surfaces may cause burns.

Product Description

The POE.8AT-DC1 is a DIN-rail mountable injector, which provides power for Power over Ethernet (PoE and PoE+) applications. It injects power to 8 individual PoE channels (IEEE 802.3at) via RJ45 Ethernet ports to supply powered devices (PD) of type 1 and type 2.

Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any kind of loads according to IEEE 802.3at. Do not apply return voltages from the load to the output terminals higher than 56V. The device is equipped with an over-current protection for each PoE output channel. If the current exceeds the output current limitation value, the affected PoE channel will be switched off. Unplug the affected channel for at least 2s. If the over-current is cleared, the device will operate normally again. The device detects connected PoE loads automatically and will not power connected non-PoE devices according to IEEE 802.3at.

Intended Use

This device is designed for installation in an enclosure and is intended for commercial use, such as in industrial control, process control, monitoring and measurement equipment or the like. The device is suitable for indoor applications. Outdoor applications are also allowed as long as all requirements specified in this manual (enclosure, controlled environment, condensation, …) are met. Do not use this device in equipment, where malfunctioning may cause severe personal injury or threaten human life without additional appropriate safety devices, that are suited for the endapplication. If this device is used in a manner outside of its specification, the protection provided by the device may be impaired.

Installation Instructions

Install device in an enclosure providing protection against electrical, mechanical and fire hazards. Install the device onto a DIN-rail according to EN 60715 with the RJ45 input connectors on the bottom of the device.

Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are suitable for the operating temperature of the device. Ensure that all strands of a stranded wire enter the terminal connection. Unused screw terminals should be securely tightened. Use shielded twisted pair Ethernet cables specified for usage in IEEE 802.3at. The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed. The enclosure of the device provides a degree of protection of IP20. The enclosure does not provide protection against spilled liquids.

The device is designed as “Class of Protection III” equipment according to IEC 61140. The device can be supplied from batteries or similar DC sources. The voltage between the supply terminals and ground must not exceed 60Vdc continuously. In order to fulfill the IEEE 802.3at requirements, the external power source and wiring connected to the supply voltage terminals need to have a minimum isolation strength of 1500Vac to ground. Check for correct input polarity. The device will not operate when the voltage is reversed. The device must be supplied from a PELV or SELV source or an “Isolated Secondary Circuit” in order to maintain a SELV or PELV output. A minimum input voltage of 52Vdc is required to fulfill the IEEE 802.3at requirements with 30W (PD type 2) per channel. If the voltage is lower than 52V, only devices with a power requirement of 15W (PD type 1) can be supplied

A disconnecting means shall be provided for the input of the device. There is no input inrush current limitation included. The internal input capacitor of typically 100μF will be charged without any specific limitation means when connected to the supplying system. Use an external circuit breaker with 6A B- or 4A C-Characteristic for the supply voltage input if the current of the supplying source is higher than 7A. The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover ventilation grid!

The device is designed for altitudes up to 2000m (6560ft). Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%, the 5mm can be reduced to zero. The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the same as the ambient or surrounding air temperature and is defined 2cm below the device. The device is designed to operate in areas between 5% and 95% relative humidity. Do not plug or unplug the device as long as input voltage is present. Do not unplug the supply voltage connectors more often than 20 times in total.

Technical Data

All values are typical figures specified at 53Vdc supply voltage, 8x 30W output load, 25°C ambient temperature and after a 5 minutes run-in time unless otherwise noted.
