GE A06B-6087-H115 Servo Power Supply

The GE A06B-6087-H115 provides DC bus power to servo amplifiers in GE Fanuc CNC systems. You can install this unit into the main drive cabinet of Series 15 or 16 controllers. It converts three-phase AC input into regulated DC voltage for servo motors. This supply supports high-torque machining and rapid traverse applications.

Technical Specifications and Hardware Configuration

This servo converter power supply measures 310 mm in height. Its width reaches 180 mm, and the depth equals 250 mm. The GE A06B-6087-H115 weighs approximately 8.5 kilograms. The unit contains multiple power boards with IGBT switching circuits. It includes eight large electrolytic capacitors for bulk energy storage. These capacitors maintain DC bus voltage during peak torque demands. One 5-pin screw terminal block accepts three-phase AC input wiring. A dedicated 4-pin connector delivers DC bus output to servo amplifiers.

Electrical Ratings and Performance Characteristics

The GE A06B-6087-H115 accepts input voltages from 200 V AC to 230 V AC three-phase. It operates at line frequencies of 50 Hz or 60 Hz automatically. This unit delivers a DC bus voltage of 300 V DC at 30 A continuously. Peak current reaches 90 A for up to 3 seconds during acceleration. Efficiency reaches 92 percent under typical operating conditions. Consequently, this supply powers multiple servo axes simultaneously. Overvoltage protection clamps the DC bus at 400 V DC maximum. Internal regenerative resistors dissipate braking energy from decelerating motors.

Installation and Operational Guidelines

You must mount this unit vertically inside the CNC drive cabinet. Transitioning to wiring, use 6 mm² stranded copper wire for AC input connections. A green front LED indicates normal DC bus voltage presence. The internal fan requires 50 mm of free space at the intake vents. For safety, discharge the internal capacitors for ten minutes before servicing. The operating temperature range sits between 5°C and 45°C reliably.
