Technical Specifications​

Input is 100 to 240 volts AC, single phase, 50 or 60 hertz. Outputs are 12 isolated DC channels: 8 channels at 24 volts DC with 5 amps maximum each, total 30 amps, and 4 channels at 48 volts DC with 3 amps maximum each, total 12 amps. Isolation is 2.5 kilovolts AC input to output and 1 kilovolt AC output to output. Voltage regulation is plus or minus 1 percent at 90 percent load. Efficiency is 92 percent or higher at full load with 230 volts AC input.

Functional Features​

Per-channel overvoltage, overcurrent, short-circuit, over-temperature and reverse-polarity protection. Real-time voltage, current and temperature monitoring. Power consumption logging per channel. Configurable protection thresholds reduce collateral impact during single-channel faults.

Application Scenarios​

Used in Centura etch, Sym3 CVD and Versys metal deposition systems. Suitable for 300 mm wafer fabs requiring isolated power for motion, DAQ, thermal and vacuum subsystems.

Performance Parameters​

Communication interfaces include RS-485 and USB-C. Protocols include Modbus RTU and proprietary Lam power-link communication. Operating temperature is 0 to 50 degrees Celsius. Relative humidity is 5 to 90 percent non-condensing. MTBF exceeds 250,000 hours in listed industrial qualification data.

Material Composition​

Corrosion-resistant aluminum housing, conformal-coated PCB, industrial power semiconductors, magnetic components, isolation transformers or opto-isolated circuits, and ESD-protected assemblies.

Structural Characteristics​

19-inch rack mountable 4U body. Dimensions are 250 millimeters wide, 320 millimeters high and 160 millimeters deep excluding connectors. Two 60-pin terminal blocks handle input and output power. Two variable-speed fans and passive heat sinks provide cooling.

Working Principle​

AC input is rectified and regulated into isolated DC rails. Each output channel is independently controlled and monitored. Protection logic isolates a faulted channel without shutting down unrelated channels, maintaining continued operation of critical subsystems.

Installation Requirements​

Mount in a 19-inch rack with adequate clearance for airflow. Connect AC input through approved facility disconnects. Torque terminal blocks to specification. Configure RS-485 or USB-C monitoring before system energization. Verify SEMI S2, S8 and S14 compliance documentation for site acceptance.

Usage Precautions​

Do not exceed per-channel current ratings. Maintain ambient temperature below activation limits for over-temperature protection. Use ESD-safe handling for board service. Review 90-day power logs to identify aging motors or rising leakage currents before failure occurs.
