Neuer PoE-tester erhöht zuverlässigkeit bei der installation von PoE-geräten

Der renommierte Messgerätehersteller, TREND Networks, bringt einen neuen Handtester auf den Markt, der die Aussagekraft der Messungen bei der Installation, Wartung und Fehlerdiagnose an PoE-Geräten und -Datenkabeln deutlich erhöht. Der neue „PoE Pro“ ermittelt die PoE-Klasse, -Spannung, -Leistung und den -Typ, so dass der Techniker sofort weiß, wieviel Leistung zur Verfügung steht.

Mit dem neuen PoE Pro fällt das zeitaufwändige Herumprobieren bei der Installation und Fehlerdiagnose von PoE-Systemen weg und Kabelinstallateure können die am Standort maximal verfügbare Leistung exakt messen.

Power-over-Ethernet (PoE) wird beispielsweise genutzt, um VoIP-Telefone, intelligente Beleuchtungssysteme, CCTV-Überwachungskameras, digitale Anzeigen, WLAN-Zugangspunkte, Wechselsprechanlagen, Sensoren oder andere Geräte über das Ethernet mit Strom zu versorgen. Mit der weiteren Verbreitung von PoE sind Installateure jedoch auf einen schnellen und präzisen PoE-Tester angewiesen, um aussagekräftige Messung durchführen und den Auftrag professionell und kundenorientiert abschließen zu können.

Bisher mussten die Techniker die einzelnen Standards, Ausgangsleistungen und Kabellängen von PoE kennen, um sicherzugehen, dass ein angeschlossenes Gerät ordnungsgemäß betrieben werden kann, was oftmals zu subjektiven Fehleinschätzungen geführt hat.

With the PoE Pro from TREND Networks, users can see immediately whether a device that requires 75 W, for example, such as a POS / kiosk system or a digital display at an airport, really gets this performance. Thanks to the OK / error evaluation displayed by the tester, the installer is certain that the PoE device also works perfectly.

The measurement results up to 90 W (PoE ++) are immediately and clearly displayed on the large, backlit display. The tester displays the voltage, the performance class from 0 to 8 and the PoE type (af, at or bt) regardless of the length and quality of the cable. It is advantageous that the PoE Pro does not have to be set or configured first. It is simply connected to the data cable and immediately provides information about the maximum available power.

Problems with the cable, the switch or the device are easily identified and the technician knows immediately whether the switch is feeding enough power. He also sees which line pairs are occupied with PoE. This makes it possible to differentiate whether the supplier (PSE) is a switch or a midspan injector.

The technician can also do without additional testers, since the PoE Pro checks both data cables and the PoE function. For this purpose, the compact tester offers all cable test functions of the VDV II Pro from TREND Networks. Based on the comprehensive information on the fault locations, such as interruptions, short circuits, crossovers and split pairs, the PoE Pro detects wiring errors immediately. The TDR function determines the cable length and the distance to the fault location with high accuracy. The PoE Pro speeds troubleshooting and helps prevent failures and potential damage to cable fasteners.

The tester determines the Ethernet data rate (10/100/1000 Mbit / s) and immediately shows which media service, such as Ethernet, ISDN, PBX and PoE, is transmitted via the cable, which further reduces the time required for error diagnosis. The technicians can also recognize the switch port by flashing the port and identify the required cable with the integrated tone generator and a supported inductive receiver (line finder).

Conclusion: The PoE Pro is a comfortable tester for the professional installation of security, IT, communication and lighting systems. The integrated RJ11 / RJ12 (voice), RJ45 (data) and F (video) connections accelerate the testing of most types of low-voltage lines in all projects. He is the tester of choice to control the PoE function and to provide accurate proof of performance.

The PoE Pro is available from TREND Networks dealers worldwide, but can also be purchased directly from the company’s online shop. For more information, go to www.trend-networks.com .
