• Input voltage: 115/230 VAC (single phase), 50/60 Hz

• Output power: Suitable for 0.5–1.0 HP AC motors

• Main circuit: AC-DC rectification + DC-AC inversion, IGBT power components

• Control power supply: +5V/3A, ±15V/1A (generated internally, for system boards)

• Synchronous interface: In/Out synchronous transmission port (multi-machine synchronization)

• Operating temperature: 0–55°C; Storage: -20–70°C

• Dimensions (width × height × depth): Approximately 30×220×180mm

• Weight: Approximately 2.2kg

• Installation: PMI rack-specific power slot, front panel fixed

• Insulation withstand voltage: Input/output and logic side 2kV AC/1min

• Interface and communication configuration

• Front panel:

• LED indicators: OK (green) - normal power supply; FLT (red) - fault

• Interfaces: In/Out Synch (synchronous signal reception and transmission, multi-machine parallel / synchronization)

• Fixing screws: 2 pieces, used for rack locking

• Backplane gold fingers:

• Power bus: AC input, DC bus, AC output

• Control bus: Enable, fault feedback, power ready, synchronous signal

• Power: Supply for control board and CPU board in the rack Core function

• AC-DC-AC Power Conversion: Convert the input alternating current into a DC bus, then invert it into adjustable-frequency and adjustable-voltage alternating current to drive the motor.

• System Control Power Supply: Generate +5V and ±15V stable power supplies to supply power for the CPU board, I/O board, and communication board.

• Multi-machine Synchronous Control: Achieve parallel connection of multiple modules or synchronous transmission of multiple axes through the Synch interface, ensuring consistent speed and phase.

• Fault Detection and Protection: Overcurrent, overvoltage, undervoltage, overheating, short circuit, and phase loss detection, triggering protection and locking the fault.

• Heat Dissipation Management: Integrate temperature sensors and cooling air ducts, automatically reducing power or shutting down for protection when overheated. Applicable scenarios

• Industrial AC drive: Low-voltage AC motors drive small rolling mills, fans, water pumps, conveyors, extruders, etc.

• Core of AutoMax PMI AC system: Compatible with PMI racks (such as 57C series), replacing the old version 0-60023-1/3/4.

• Multi-machine synchronous drive: Production lines that require multiple motors to run synchronously (such as textile, papermaking, cable equipment).

• Maintenance of old production lines: Replacement of power spare parts for AC drive equipment in suspension production to avoid entire line renovation and reduce costs.

• User and maintenance instructions Installation

• When the power is off, insert the PMI rack power slot and tighten the front panel screws; do not perform hot swapping to prevent power components from burning out.

• Installation location: Ensure that the heat dissipation airflow is unobstructed, keep away from heat-generating components, and avoid dust accumulation.

• Wiring

• Input: Connect according to the nameplate to 115/230 VAC, single phase, L/N/PE.

• Output: Connect to the three-phase U/V/W of the AC motor, pay attention to the phase sequence.

• Synchronization: When there are multiple machines, use shielded wires to connect In/Out, and set the terminal resistor to ON.

• Daily maintenance

• Every 3-6 months, power off and blow off dust, check the status of power components, capacitors, and cooling fans.

• Observe LEDs: OK always on is normal; OK off → power failure; FLT on → fault (overcurrent / overvoltage / overheating).

• Fault troubleshooting

• No output: Check the input voltage, fuse, rectifier bridge, IGBT, DC bus voltage.

• Overheating: Check the heat dissipation airflow, fan, load rate, and environmental temperature.

• Synchronization anomaly: Check the synchronization wiring, terminal resistor, and module parameter matching.
