introducing TW-IDU-Node 2 the smart power supply for PoE devices

Thanks to smart PoE supply every standard and not standard load such as PoE+, 802.3af & 802.2at devices, IP-Cameras, IP-Phones, PBXs, Access Point, Switches, CPEs, Routers, providing Output Voltage in case of black out. The Output supply is selectable in continous way between 24V up to 52V.

an integrated strong Lightning Protection from overvoltage and shocks

Battery sharing

a recharger for 12V battery allow to improve a complete UPS system. One battery more PoE for recharge toghter one big battery, no SPOF technology (Single Point Of Failure)


use Solar Panel Plug & Play

Work as step-up way

Intelligent Power Management

reserve energy on lower radiation


a complete Protection

PoE Output

Software overcurrent protection when overloaded and/or output shortcircuit occur

Battery Input

Deep Discharge Voltage Management

Data & Power Line

Lightning protection 25KA (8/20us) differential mode

DC Input

Polarity reversal protection. Overvoltage protection up to 43Vdc



NO-SPOF design

DC input sharing

In a clustered environment DC input is superimposed to battery and AC input

Charge & back-up battery sharing

In a clustered environment one big battery compensate single failures, and charging continuing with remaining PoE injector

Power failures compensating

In a clustered environment other PoE injector compensate for power failures

BUS monitoring

Every failures generate an alarm in the communication bus (CAN-bus)


din clip is included


Din Clip for Robust & Reliable installation

Din Clip located in a rear side of device permits to align more TW-IDU-NODE to the same Din Bar. The installation is fast, safe and reliable, reducing dimensions.


Embedded Microprocessor with EEPROM

Embedded microprocessor with I/O & ADC (Analog to Digital Controller) ports collects energy station data such as data log, input/output voltage, supply status, current monitor, temperature monitor etc. It is possible also without supply.

Remote Management with web interface

Device perfomance can be controlled in remote way by means OS Node operating system. The management can be realized with PC or Tablet. Buying OS Node and downloading configuration is possible to activate the interface in own device.

New Hardware more reliable

New design, new temperature extended range microprocessor (- 40+85°C). Improved MTBF by means more performing and drastic capacitors reduction. Thermal management more reliable and new and fast electronic protections against overload and short circuit (0,1ms).

USB port for remote control

USB port permits PC interface for device remote monitoring: switch on/off, firmware updates, shell settings etc. It is possible to connect a routerboard in order to manage entire informations at physical layer over CAN bus (serial emulation). Each information will be sent to Townet OS Node, new device manager and monitor , with logging and events interface.

Can Bus and 1Wire

with CAN Bus is possible to connect several TW-IDU-Node among them for a single remote management. Also the Node can talk together with entire CAN based devices, compatible to sensor applications. Is also allowed to connect multiple temperature sensor by means 1wire bus port for domotics applications.
