Product Description:
The E4809-045-229 circuit board is utilized in industrial control systems and provides regulated voltage outputs required by various internal circuits of CNC or automation equipment. It is made by Okuma and the firm gives innovative products that lead industrial automation standards for reliability.
The E4809-045-229 circuit board is a power supply unit with an approximate weight of 0.41 kilograms. The board integrates multiple aluminum electrolytic capacitors typically rated between 200 V and 450 V with capacitance values in the range of 220 micro-Farad to 470 micro-Farad to smooth the DC voltage after rectification and reduce voltage ripple within the supply lines. It contains toroidal inductors with copper windings between 10 micro-Henry to 1milli-Henry that function in filtering and energy storage stages within the switching power which is effective in decreasing electromagnetic interference and supporting DC-DC conversion processes. Rectification is handled through a bridge rectifier package by converting AC input into DC configuration. These rectifiers are generally rated from 600 V to 1000 V and handle current loads between 4 A and 10 A. A relay is installed with almost a 12 V or 24 V coil and is capable of consuming up to 10 A for controlling high-energy circuits.
The E4809-045-229 circuit board black heat sink uses power semiconductors as MOSFETs or voltage regulators. It is designed on a printed board-type layout and the small transformer located beneath the central thermal sink helps to provide galvanic isolation and scaling for system safety. Opto-couplers are used near the control area to isolate feedback loops for logic control. Connectors include high-current terminals and a multi-pin header aids in supplying ease for distribution and logic interfacing.
