The Fanuc A16B-1212-0950 is a power supply unit manufactured by FANUC. It is a printed circuit board (PCB) power supply unit designed for use in CNC (Computer Numerical Control) systems. The power supply unit is equipped with a CE marking, indicating its compliance with European Union safety standards. These products are manufactured in Japan and are designed for Commodity production, advanced machining, and CNC milling usage. They come with a 2-year warranty from MRO Electric. We also carry Power Supplies from other manufacturers such as Siemens and Control Techniques.
The A16B-1212-0950 power supply unit is specifically designed for easy mounting and dismounting. It can be directly connected to the master printed circuit board and all its AC inputs and DC outputs are linked via connectors. This design feature simplifies the installation process.
One of the notable features of this power supply unit is its built-in input unit function. Unlike some other power supply units, there is no need for a separate relay or input unit to switch the AC input on and off. The AC input can be directly connected to the power supply unit. Additionally, the unit includes an AC service outlet that is switched on and off simultaneously with the power supply unit. This outlet can be used to provide power to other devices such as a fan motor.
The power supply unit features several signal indicators and display LEDs. The AC power supply display LED, when connected to an AC power source, lights up regardless of whether the unit is on or off. The alarm display LED, on the other hand, lights up in red if the power supply unit is switched off due to an alarm condition, such as an output error. The ENABLE signal (EN) is an output signal that indicates the normal functioning of all DC outputs. It becomes low if any output failure is detected. The power supply on/off control signal (ON-OFF-COM) is an input signal that controls the operation of the power supply unit.
The power supply unit has various input/output connectors that serve different purposes. CP1 is the connector for the 200/220/230/240 VAC input, while CP2 or CP3 is used for the 200/220/230/240 VAC output, which is switched on and off simultaneously with the power supply unit. CP4 serves as the power on/off switch contact signal input, as well as the external alarm signal input. CP7 is responsible for supplying +5V, +15V, -15V, +24V, and +24E to the master printed circuit board, and CP5 supplies +24V to the 9" monochrome CRT/MDI unit.
An external alarm signal (AL) is an input signal that turns off the power supply unit when a contact signal from another unit or external power supply becomes closed. The alarm signal (FA-FB) is a contact signal that indicates the state of all DC outputs. It is open when all DC outputs are normal and closed if any output failure is detected. These signals provide important information about the status of the power supply unit and facilitate troubleshooting.
The A16B-1212-0950 power supply unit does not require any adjustments or settings, making it convenient to use. In the case of blown fuses, the unit is equipped with specific fuses (F1, F3, F4) at different points to protect the circuitry. The causes of blown fuses are listed, along with the required corrective actions to restore normal operation. These include checking for short circuits, replacing faulty components, and ensuring proper connections.
