A06B-6081-H106 is an Alpha series power supply module marked PSMR-5.5. It converts three-phase alternating current into stable direct current bus voltage to supply power for servo amplifiers and spindle amplifiers. This module matches multiple FANUC CNC control systems and widely applies to standard CNC lathes, machining centers and grinding machines.

Three-phase 200V to 230V alternating current serves as main input power with working frequency of 50Hz and 60Hz. The module outputs steady DC bus voltage ranging from 283V to 325V. Rated output power reaches 3.8kW and peak power can reach 5.5kW. Maximum input working current is 35A. External regenerative discharge device needs to be equipped to handle regenerative electric energy generated during equipment operation.

The module is designed for cabinet internal vertical installation. Internal cooling fan provides forced air heat dissipation. Normal working temperature ranges from 0 degree Celsius to 55 degree Celsius. Multiple safety protection functions include overcurrent protection, overvoltage protection, over temperature protection and fan failure detection protection.

This power unit supports A06B-6079 series servo amplifiers. It works well with Alpha-i B servo motors and Alpha spindle motors. Compatible CNC system models cover 0i-Mate, 0i-C, 0i-D, 16i, 18i and 21i series.

It maintains stable DC bus output to guarantee reliable running performance of servo and spindle units. Compact overall structure saves installation space inside control cabinet. Built-in fault diagnosis function feeds back abnormal working status timely. High power conversion efficiency lowers heat generation and power loss during long time continuous operation.

Alarm code 01 represents overcurrent fault of main power unit. Alarm code 02 means cooling fan stops working. Alarm code 03 indicates over temperature of heat dissipation base. Alarm code 04 appears when DC bus voltage drops abnormally. Alarm code 07 stands for DC bus overvoltage failure.

Cut off total power supply before installation and maintenance work. Keep sufficient ventilation space around the module to ensure smooth heat dissipation. Fasten mounting parts firmly to avoid vibration influence. Conduct regular inspection on fan running state and terminal connection tightness. Stop equipment operation immediately once alarm occurs and check circuit load and peripheral connected modules.

The power supply module is suitable for standard CNC machining centers, numerical control lathes, surface grinding machines and other common industrial numerical control processing equipment.
