Volt meter V4080

Volt meter V4080

V4080 is digital measuring, fully programmable device from series 4080, designed on basis of microcontrollers. It measures voltage in range 0-270VAC/ 380VDC (up to 600VAC/ 800VDC available - option “H”). V4080 can measure its own supply voltage (basic option, minimum voltage 30VAC/42VDC) or it can measure the voltage applied to external voltage input (options “L” or “H”). The unit can be equipped with potential-free relay contacts for remote signaling if the measured voltage goes out of certain specified range (option “R”). The unit is designed to be mounted on boards in control rooms of electrical substations.

user manual

V4080 is offered in following variety*:

- (A/D) basic version - the unit measures its own power supply voltage, there are no potential-free contacts, user menu is not code-protected
A AC voltage measurement
D DC voltage measurement
L additional voltage input, minimum input voltage is 0 VDC/VAC, maximum input voltage is 270 VAC/ 380 VDC
H additional voltage input, minimum input voltage 0 VDC/VAC, maximum input voltage is 600 VAC/ 800 VDC
R there are three relay contacts that provide remote signalization, acting when certain programmed voltage levels are reached
C code-protected user menu
X user is not allowed to change device settings
* - Every option can be ordered in any combination with other options, excluding versions “A” and “D”, which exclude each other as well as versions“L” and “H” and versions “C” and “X”. One of the options - “A” or “D” must be specified.
