Frequently Asked Questions - Energy-400R PWR Vemer
What is the Vemer Energy-400R PWR used for?
It is a three-phase power and energy analyzer used to measure electrical parameters such as voltage, current, power, and energy consumption in industrial and commercial installations.
How to install the Energy-400R PWR on a DIN rail?
The device snaps onto a standard 35 mm DIN rail. Ensure the rail is secure, clip the device onto it using the integrated spring, and tilt it slightly until it locks.
What is the maximum voltage the device can measure?
The direct voltage measurement range is 80-300 V AC phase-to-neutral and up to 520 V AC phase-to-phase. For higher voltages, use external voltage transformers.
Can the Energy-400R PWR be used with current transformers?
Yes, the device accepts signals from external current transformers (CTs) with secondary ratings of 1 A or 5 A. The CT ratio can be programmed via the front panel or software.
Does the device have communication capabilities?
Yes, it features an RS485 Modbus RTU interface for integration with energy management systems, SCADA, and building automation.
How to connect the auxiliary power supply?
The Energy-400R PWR is self-powered from the measured voltage, but also supports an external auxiliary supply of 230 V AC for isolated operation. Connect to the designated terminals.
What maintenance does the device require?
The device requires minimal maintenance. Periodically check the terminal connections for tightness and ensure the display is clean. No internal calibration is needed within the first year.
Is the Energy-400R PWR compliant with safety standards?
Yes, it meets IEC 61010-1 and EN 50470-1 standards, ensuring safe operation in industrial environments.
Can the display show reactive power?
Yes, the device measures and displays active, reactive, and apparent power, along with power factor and frequency, in all four quadrants.
Where can I find the user manual for the Energy-400R PWR?
The official user manual is available for free download on the notice-facile.com website in PDF format. You can also request a translated version if needed.
