Wega 1 LV

Integrated Voltage Testing Systems for Low Voltage Applications in accordance with IEC 62271-213:2021

Wega 1 LV is a three-phase voltage testing system that displays the following voltage states:

Indication	Definition
	Voltage present Threshold value for voltage presence indication: approx. 50 V (deviating from the percentage thresholds of IEC 62271-213!) Installation note: The voltage signal is too low when operating the system at nominal voltage. The cause is usually an incorrect use of the Wega 1 LV, e.g. the operation of the switchgear at a nominal voltage that is lower than originally envisaged.
	Voltage present and passed maintenance test The current flowing through the display unit meets the current monitoring requirements of IEC 61243-5 (section 5.28) and IEC 62271-213 (section 11.4.2). A repeat test is not necessary due to the continuous monitoring.
	No voltage present When the system is switched off at all poles, all symbols are switched off. Voltage applied <50V (deviating from the percentage thresholds of IEC 62771-213!).

Fully encapsulated electronics – High operational reliability under all environmental conditions
Integrated repeat testing – Maintenance-free
Developed according to IEC 62271-213 – Proven safety concepts from high voltage for low voltage applications
Front LRM interface – Phase comparison according to IEC 62271-215 (e.g., Orion 3.1 / M1) possible
Tool-free installation – Saves installation time
-40°C to +75°C – Extended temperature range for various applications
High display contrast – Excellent readability
