PoE power supply has integrated 24-port Power-over-Ethernet injection specifically for switch and PBX applications. The unit provides 12-volt DC output for switch and 50-volt DC output voltage per port in PoE, and can implement eight- to 24-ports in a PoE system, making it suitable for applications such as 10/100 Base T Ethernet switches, security systems, VoIP phone systems and blade servers.

Web-enabled unit substation is equipped with an Ethernet interface and web server, to provide access to power system information, including transformer coil temperatures, using a standard Web browser. The pre-engineered equipment ships in standard lead-times and connects to a customer’s existing Ethernet LAN much like adding a PC or printer.

Insulation testers are capable of delivering multiple test voltages and are designed to provide rugged reliability and ease of operation for a wide range of troubleshooting, commissioning and preventive maintenance applications.

One model features automatic one-button calculation of polarization index and dielectric absorption ratio, and also has a compare (pass/fail) function designed to ease repetitive testing. For more about 1507 and 1503 meters from Fluke, click here .

High Density Power UPS offers a suite of on-line features in a compact package. The unit combines 6 kVA power capacity, flexible output voltage, internal batteries and an integrated maintenance bypass switch. Consisting of two 3-kVA 120-volt inverters, its dual inverter engineering permits flexible output voltages to meet mixed load voltage requirements.
