Three-Phase Constant Current Regulator
The three-phase constant current regulators, series UR3000, particularly designed to provide power to airport lighting series circuits, provide input phase balance, high power factor, high efficiency and sinusoidal output current independently of the load size.
These constant current regulators are suitable for operation under the following environmental conditions:
– protected ambient
– temperature comprising between – 20° C and + 50° C, including monitoring circuitry
– height above sea from 0 up to 2000 m
– humidity from 10% through 95% (not condensing).
COMPLIANT with the Current Edition of the following Specs:
