PCI Systems integrates Spread Spectrum Clocking into all Power Supplies for ultimate low EMI

PCI Systems extremely low EMI Power Supply line

Sunnyvale, CA — PCI-SYSTEMS Inc. , a leading supplier of conduction cooled systems, today announced that all Power Supplies with SMART.PSU Technology incorporate SSC- Spread Spectrum Clocking for extremely low EMI

The first module in a wide selection of form factors and power levels is a 3U, 500 W power supply.

This 3U power supply works with 16 to 36 VDC (28 VDC nominal) input voltage and isolates the input voltage ground from the output voltage ground. The power supply is conduction cooled, uses poly-phase technology on all voltage rails and can provide up to 500 watts. It is suitable for use in mission critical rugged applications.

[SMART.PSU] PCI-Systems Inc. intelligent power supplies integrate a microcontroller (MCU) for a fully programmable and flexible solution. Intelligent power conversion allows configuration and reconfiguration for different applications. With intelligent power conversion, the power supply becomes a platform solution for Vita 46.11 system management based systems. The power supply can easily be reprogrammed to support different operating limits and control inputs.

Features:

• Parallel operating with multiple power supplies, all rails

• Load sharing and balancing

• Digital On/Off control for low standby power

• Input / Output Voltage rail setting /adjustment

• Spread Spectrum Clocking of power supply stages

• Possibility of external synchronization

• Power supply sequencing and hot-swap control

• Power supply history logging and fault management

• Monitoring output voltage, current and power

• Current fold back control

• Automatic temperature drift compensation for all outputs
