Used ELC ALR 3003 #9264401 for sale

ELC ALR 3003 is a three-phase voltage regulator designed for controlling the production of direct-current power. The device is powered from an AC source and converted to neatly regulated DC output, up to 450V / 10A, thanks to the switching power stages. With two onboard DIN-rail style terminals and a safety-rated enclosure, ALR 3003 is well-suited for a range of electrical and industrial applications. The device comprises of two separate parts: primary control and secondary stabilisation. The primary control provides an input power of three-phase AC voltage ranging from 110V to 440V, and accordingly determines the voltage value within specified limits. The output is then monitored and adjusted, if necessary, by the secondary stabilisation. In this way, ELC ALR 3003 brings stability to the power production, thus eliminating the risk of power losses due to transients. Safety is a priority at ELC, thus ALR 3003 has been designed to offer maximum levels of protection from power surges, overcurrent, overheating, reverse-polarity and short-circuits. For added durability, the outer shell of the device has been constructed from rugged alu-die-cast with an IP20 protection rating. ELC ALR 3003 offers excellent precision and accuracy, with a voltage regulation tolerance of +/- 1%, and a harmonic distortion component (THD) up to 3%. The device also features a high efficiency, as high as 95%, and is equipped with a smart cooling system which allows constant output power with minimum heat dissipation. To further optimise performance, ALR 3003 includes an array of digital features, such as four-digital inputs, two analogue inputs, and dedicated RS-485, Modbus and Ethernet interface ports. The user can also program multiple parameters relating to the output power, such as voltage, frequency, alarm settings and ripple filter settings. The device also offers a wide range of protection, monitoring and diagnostic functions to guarantee the longevity of the equipment. Overall, ELC ALR 3003 is an advanced and reliable three-phase power supply designed to provide maximum levels of safety, accuracy and efficiency in a variety of industrial and electrical applications.
