Function and purpose

Vutlan VT-PDU 4MS Remotely Managed, Switched & Metered-by-Outlet PDU is a small unit with x4 outlets, 110/240V. Each of the four IEC-320 C13 outlets of this Power Distribution Unit can be independently controlled (On / Off / Reset / Toggle) and metered. Electrical parameters (Voltage, Current, Power, Frequency, Active / Real power, Active / Real energy) are measured with high accuracy at each outlet. The device features a LAN port (and a built-in Ethernet switch) for connecting to a LAN. Each power output supports Zero Current Switching to protect the connected equipment. 

Outputs can be controlled in the device Web Interface, using a mobile app, or over various M2M API protocols (REST API, SNMP).

Key Features:

• Environmental Monitoring: A CAN port allows connecting digital CAN sensors and CAN extensions in a chain to continuously measure essential environmental factors to ensure optimal conditions, preventing equipment damage and operational failures.

• Flexible Configuration: Users can manage up to 24 CAN devices, 300 different elements, including notifications, triggers, timers, and logic schemes, allowing for tailored monitoring solutions that meet specific needs.

• User-Friendly Interface: A built-in web interface provides access to virtual sensors, logic schemes, and diverse notification types, simplifying user interaction and enhancing accessibility.

• Remote Connectivity: Mobile-friendly web interface offers easy management and monitoring of all outputs and sensors.

• USB camera: Record a JPEG stream in the alarm event.

• Logs: SDHC or SDXC memory cards up to 512 GB allow for storing data for up to 5 years.

• Banking & Retail

  • Ensures the continuous operation of ATMs and POS terminals.

  • Manages power for surveillance cameras and security systems.

• Healthcare

  • Controls power for medical equipment and patient monitoring systems.

  • Ensures the reliable operation of hospital servers and information systems.

• Telecommunications

  • Enables remote management of base stations, network switches, and signal repeaters.

  • Automates system reboots in case of failures.

Power measurement

Vutlan VT-PDU 4MS measures electrical parameters separately for each output. Measured values are displayed in the web administration interface and accessible via M2M protocols. Vutlan VT-PDU 4MS measures with an accuracy of better than 1%.

• 4x Current [A]

• 4x Power [W]

• 4x Voltage [V]

• Frequency [Hz]

PowerUp state

For some applications, it is important to set the correct state of a power output immediately after power is turned on (or restored). The “PowerUp state” parameter defines the behavior of the 110/230V outlets just after power is restored, before the standard communication with the master system is established.

• On 

• Off 

Scheduler (timed switching of individual outlets)

The switching of outlets can be time-controlled by the Timer with a graphical interface. Switching on/off at specific times can be easily configured.

• Each output can have its own schedule/timer, according to which the output is switched

1. DC 12V POWER: Keeps the PCB running and allows sending alarm notifications if the main C14 inlet loses power.

2. Chassis grounding: Chassis grounding, M4 thread. Enhances the immunity of the equipment against conducted and radiated RF disturbances. Please contact a professional electrician before connecting it.

3. INLET FUSE: 10A 5x20mm

4. INLET: C14 inlet, 110-240V AC, 50/60Hz, Fuse 10A 5x20mm

5. OUTLETS 1-4: x4 C13 outlets 110- 240V AC, 50/60 Hz. Read more at Relay switching (NC NO) / Outlets switchingRelay switching (NC NO) / Outlets switching.

6. TEMPERATURE SENSOR: accuracy +/- 1 °C

7a. Factory reset: Reset settings to the default factory settings. Keep pressing the button for more than 5 seconds. The “ERR” LED will start blinking. This indicates that the factory restoration has started. Wait for 20-60 seconds for the system to restart. The “ACT” LED will start blinking once the system has been restarted. The device can be accessed now.

7b. Restart: The button restarts the appliance. Hold the button for 2 seconds and then let go, and the system will restart.

8a. R1, R2, R3, R4: LED status indicators for the status of x4 C13 outlets.

• The LED is ON (orange) - the relay is ON (the initial state can be configured).

• The LED is OFF (LED is off) - the output is OFF (the initial state can be configured).

8b. LED: ALARM: The LED can be programmed from the interface for alarm indication.

8c. LED: ERR: red LED indicates error and traffic.

• The operating mode of the device: If everything is normal, the LED is extinguished; if not, there's a constant glow.

•  Software update mode: switches at a rate of 2 times per second;

8d. LED: ACT: green LED indicates appliance system status,

• - operating mode of the device: switches at a frequency of 2 times per second;

• - successful completion of the software update process: switches at a frequency of 4 times per second;

9. CAN: digital connector RJ12 6P4C for the connection of CAN sensors/extensions/devices on a CAN bus. Modules can be chained together. Read the instructions in "CAN devices connection", and "Setting up CAN".

• LED: CAN: green LED indicates CAN bus status.

• The LED blinks slowly - nothing is connected

• The LED blinks fast - configuration is in process

• The LED glows constantly, connected to CAN devices

10. LAN port: Ethernet 10/100 Base-T port, provides an Ethernet connection. Read more in this section, "LAN, LTE, RADIUS, DNS, SSL, VPN".

• Orange LED: The Orange LED is for the Ethernet port. It shows network traffic.

• Green LED: green LED for Ethernet port. It shows network traffic. Flashes green when the system starts up. Shows the connection state (constant green light - the connection is established, blinking green - the connection attempt).

11. SD card: MicroSD card slot with an ejector. The card is needed for data storage or the "system restore". Read instructions at "Saving system logs to SD card", and "Restore of the appliance (for VT960 series)"

12. "Dip switch N… R"

• Normal mode: The switch is switched to the left ←. The switch should always be in this position.

• Restore of appliance: The switch is switched to the right →. Used to load the clean system image from an SD card. Read instructions at “Restore of appliance”

13. USB: Micro USB-port 2.0 is needed for USB camera recording, USB Flash for system logs, and system restoration. Read instructions at "Connecting USB camera", "USB camera settings. How to save a video", "Saving system logs on USB flash drive", and "USB upgrade or restore of default settings".
