Ametek has introduced a 30 kW water-cooled ASD (Advanced Sorensen Design) series programmable power supply.
The 3U unit is designed for excellent load transient response with low output ripple and noise, and its water-cooling packaging enables use in environments that normally exclude air-cooled power supplies.
The ASD’s advanced digital architecture, with real-time digital control and graphical user interface, enables many features to better control and monitor the process or application. The optional advanced features package includes a built-in oscilloscope function for measurement and display of power, voltage, current, output impedance, output cable impedance and output cable voltage drop.
The power supply allows for programming different fault levels, enabling detection of output cabling, connections or load problems before they cause critical system errors. The ASD can replace a PLC device by closing the loop on an external parameter such as temperature.
The unit’s Advanced Diagnostics and Maintenance (ADAMsm) feature includes a flight data recorder feature that allows the user to access multiple recorded parameters, such as voltage, current, power, load impedance, faults and input voltage. This allows the user to easily determine why there has been an unexpected outcome.
The power supply allows for precise programming of voltage and current slew rate for sensitive loads. Modules within one chassis can be connected to different loads and controlled independently, and an industrial field bus interface (Modbus-TCP, Modbus-RTU, Ethernet/IP) enable real-time digital control.
A built-in energy meter calculates the delivered energy throughout a process or period of time, while an optional real-time clock enables accurate time stamping of events. Load impedance measurement, including rate-of-change calculations, enables load ‘state of health’ monitoring and implementation of system preventive maintenance algorithms
