The light LEDs components are spatially arranged as a light source with required optical features. LEDs are electrically connected into two identical chains, their lighting is monitored by safe electric circuits type file-safe, coupling of these checking circuits with LCI technology is made by relay type NMŠ1-2000.
LED road warning devices series NSVX LED and NSV2M LED together with interface MDBS01 are resolved for power supply from double-acting oscillation bus. The road warning devices NSVXS LED and NSV2S LED together with interface MDBSO1S are determined for power supply by flasher with single-acting switchers. Electric circuits are made as modules in plastic boxes which allows their easy and quick replacement. Inside of cases of warning devices there are modules inbuilt in instrument boxes.
