VOLTAGE INDICATOR 3-PHASE 230/400V AC TYPE: LDM-30
Product Description
The LDM-30 device is used for
graphic presentation of the three-phase
voltage supply system level. Voltage
value is shown by means of a three
diode line consisting of 11 LED diodes.
The display range is from 195 to 245 V
~ for every phase. The device’s system
is powered from L1 phase, and its lack
causes total device switch off.
