The ePowerSwitch 4M+ is the most sought-after Power Distribution Unit in the Neol ePowerSwitch product family. Its compact design, integrated web server, and flexible expandability to up to 36 controllable power switches make it an excellent tool for data centers and beyond, along with its capabilities in environmental monitoring. The ePowerSwitch 4M+ offers numerous applications due to its compact dimensions, not only in IT environments. A total of 4 IEC320 power switches are available, which can be switched individually or as any group. The proprietary xBus connection (standard RJ45) is available for expansions, allowing the system to be expanded to up to 36 IEC320 power switches. The master device features an integrated web server and offers convenient configuration via a web browser. Each power switch can be turned on, off, or rebooted via IP or an RS232 interface. This can be done through the web interface, a KVM switch, SNMP, or any serial interface. They can be controlled individually or as a custom group, including connected expansion devices. The sequential switching on and off effectively prevents load spikes within the IT environment.
