FANUC System 6 Power Supply A14B-0061-B103

The Fanuc A14B-0061-B103 is an Input Power Unit (I/P Unit) that serves as the power feed source for Fanuc SYSTEM 6 CNC controls. It functions as an upstream relay module that receives the incoming supply voltage and forwards it to the actual control power supply unit. Earlier Fanuc control generations divided the power supply into two separate units: the actual power supply unit (PSU) and the input unit (I/P Unit), with the A14B-0061-B103 fulfilling the role of the input unit. The component is used in Fanuc SYSTEM 6 controls, including the variants 6M (for machining centres) and 6T (for lathes) as well as the Fanuc System 6 Model A. It is a single-phase, low-power variant that processes the incoming mains voltage and delivers a 200-volt output via internal relays, which feeds the control's power supply unit. The associated control board A20B-0007-0340 manages the I/P unit and acts as an alarm circuit upon detection of faults. The A14B-0061-B103 is not interchangeable with other I/P units due to its specific connector configuration. The unit is designed for single-phase operation and processes input voltages before they reach the more sensitive components of the control. Despite the robust design of these assemblies, voltage spikes from the supply network can lead to failures; in the event of damage, repair is generally not possible. The customs tariff number is 85389091.
