Overview
The SmartPDU is optimized for power supply of end devices in data and network cabinets with simultaneous power monitoring, consumption data logging and environmental monitoring and is typically mounted in a 19 inch rack. With the integrated PowerManager and MultiSensor, up to 100 SmartPDUs can be easily managed. The integrated PowerManager is network-compatible and is supplied with power via Power over Ethernet (PoE).
The SmartPDU can be operated as the main device (Main Device mode) or in a network (Satellite Device mode) with other SmartPDUs and other Kentix devices. The KentixONE software is already integrated via the integrated web server (HTTPS). Configuration is performed via web browser and, depending on the operating mode, locally on the SmartPDU itself (operating mode: Main Device) or on a central instance such as SiteManager or PowerManager (operating mode: Satellite Device).
With its small size of only 9 cm (two height units), the SmartPDU-2U is ideal for smaller server racks. Despite its small size, the SmartPDU delivers up to 4.6 kVA of output power, distributed across 16 C13 (IEC 60320-1) appliance outlets. The SmartPDU-2U is also available as a two-phase variant, so that electronic terminal devices are protected against possible failures by two separate power supplies. The two-phase SmartPDU is supplied with power via two C20 (IEC 60320-1) IEC sockets on the rear panel. The single-phase SmartPDU is supplied with power from the rear via a C20 IEC 60320-1 socket.

Functionalities
Cable fuse
Each SmartPDU is equipped exclusively with IEC lock device sockets. This prevents accidental disconnection of the connection cables on the PDU side. When using the appropriate IEC-Lock connection cables, accidental disconnection of the connection cables at the terminal device is prevented. The connection cables are available in black and red.
Integrated residual current measurement (RCM): Testing according to DGUV V3
The two-phase SmartPDU-2U has an integrated residual current meter (RCM). This allows the plant inspection to be carried out in accordance with DGUV V3. This residual current measurement allows defective power supplies (server power supplies) to be detected at an early stage.
Circuit breaker
The SmartPDU is equipped with 10A circuit breakers per segment. Both circuit breakers have type C tripping characteristics for increased inrush current. This ensures that in the event of a power failure and subsequent power recovery, the fuses are not immediately tripped by the inrush current when the connected terminal devices are started simultaneously. The inrush current can therefore be 5 times the rated current for a short time. Details of the current curve can be taken from the following diagram.
I1= Fixed non-tripping current at 30°C
I2= Fixed tripping current at 30°C

Reset to factory settings
- Restart the device (disconnect and reconnect the power supply).
- The status LED lights up briefly and then goes out.
- As soon as the status LED lights up green continuously, press and hold the reset button for 15 seconds until the device emits an acoustic feedback.
- The device loads the factory settings and performs a restart.
- After approx. 2 minutes, the device can be reached with the factory settings.
All existing settings and data will be irrevocably deleted !
We recommend regular backup of the system.
Assembly instructions
The SmartPDU-2U is installed horizontally in a 19 inch rack. The SmartPDU requires two height units for installation. 4 cage nuts and the corresponding screws are used for fastening. These are not included in the scope of delivery.
Calibration of the room temperature measurement
Kentix MultiSensors record all important environmental values of a room, including the room temperature. In order to achieve the most accurate temperature possible and to trigger an alarm if the room temperature exceeds the limit value, we recommend calibrating the temperature measurement at the final installation location. This is especially necessary for sensors with Ethernet (PoE) connection, since a certain intrinsic heat falsifies the measurement. For MultiSensors with radio and battery supply, the influence of the intrinsic heat is not present.
Kentix MultiSensors are not calibrated measuring devices, but alarm devices whose measuring accuracy is completely sufficient for reliable reporting and documentation of limit value violations. The accuracy of the sensors is ±1% for temperature measurement and ±5% for humidity.
However, in order to obtain a good measurement result with reproducible measured values in the event of an alarm, the MultiSensor should be calibrated to the respective installation location after installation. To do this, the temperature in the immediate vicinity (approx. 5-10 cm away) of the MultiSensor must be measured comparatively with a room thermometer that is as accurate as possible. If there is a deviation in temperature between the MultiSensor and the thermometer, the temperature value can be corrected. This is done by entering the determined temperature difference between the MultiSensor and the room thermometer as a correction offset in the KentixONE software. The correction also has a direct influence on the measurement of the relative humidity and on the dew point calculation of the MultiSensor.
| Step | Note |
|---|---|
| Install MultiSensor at the destination. | The position and orientation of the sensor should not be changed afterwards. Keep the following in mind: – Mounting with X air opening downwards – Do not mount in air stream – Ventilation vent openings of the sensor must be free |
| Perform configuration of the MultiSensor with Kentix ONE. | |
| Earliest 30 minutes after startup match the temperature of the MultiSensor with the room temperature. | To do this, measure the temperature with an external reference thermometer in the immediate vicinity, approx. 5-10 cm from the MultiSensor. It should be noted that this thermometer also acclimatizes to the room and displays the correct room temperature only after a few minutes. |
| If a difference between the MultiSensor and the thermometer is detected, this can be entered in the “Offset” field in the KentixONE configuration of the MultiSensor. After saving, the sensor then provides the corrected measured value. | The offset can only be specified by whole degrees, i.e. without decimal places. This results in an accuracy for the temperature of +/- 0.5 degrees. |
Configuration with KentixONE
The configuration is done via web browser (HTTPS) using the already integrated KentixONE software. Depending on the operating mode (Main or Satellite) of the device, the configuration takes place on the device itself (operating mode: Main), or on a central instance such as the SiteManager or AlarmManager (operating mode: Satellite).
All information about the software is available in the KentixONE section and the related documentation.
Before you start the configuration, make sure that the software is up to date on all network-enabled Kentix devices. The version status must be the same on all devices.
