Advancing despite difficulties

 

In China, imported printing machines are mainly from brands such as Heidelberg, Manoland, Koenig&Bauer, and Komori. The installation of voltage regulators on printing machines is mainly to protect the circuit boards of the printing machines. The working voltage of Heidelberg, Roland, and Gaobao printing machines is three-phase 400V. In China, the three-phase voltage is 380V. Generally, a voltage regulator needs to be used to increase the voltage to 400V in order to ensure that the circuit board of the printing machine is not burned out.

 

Compared with other types of voltage regulators, printing equipment specific voltage regulators have the advantages of large capacity, high efficiency, no waveform distortion, and stable voltage regulation. They are suitable for a wide range of loads, can withstand instantaneous overload, can work continuously for a long time, can switch manually/automatically, and are equipped with overvoltage protection, phase loss, phase sequence protection, and mechanical fault automatic protection. The machine is reliable in operation, small in size, light in weight, and easy to use and install. (Score display and instrument indication), it has typical characteristics as follows:

 

※ High voltage stabilization accuracy: Adopting RMS true effective value sampling control board, the voltage stabilization accuracy is adjustable by 1-5%.

 

Fast response speed: less than or equal to 0.05S.

 

※ Wide load types: Suitable for all inductive, capacitive, and resistive loads.

 

※ All protection functions: equipped with overvoltage, undervoltage, overload, short circuit, overheating, and phase loss protection functions.

 

※ Wide voltage stabilization range: standard configuration ± 20%, customizable range of ± 30%~± 50%.

 

※ High overall efficiency: The regulator efficiency is ≥ 98%.

 

※ Excellent output waveform: The output voltage waveform has no distortion and no harmonics.

 

※ High degree of self-control: the system has fully automatic voltage stabilization, startup delay, and automatic recovery functions for fault relief.

 

※ Large load capacity: The voltage regulator capacity can be selected from 1KVA to 2500KVA.

 

※ All communication functions: RS485+RS232+GRPS communication methods are available, which comply with the Modbus RTU protocol.

 

※ Strong purification ability: Install a high-throughput surge suppressor at the input end of the printing regulator to solve the impact of lightning induction and interference pulse spikes on the equipment.
