Supplies deliver cost-effective performance
The PSG Series of external desktop power supplies is designed to suit a wide range of applications, and is claimed to deliver exceptional performance at an extremely competitive price.
As such, they will satisfy a wide range of applications in IT, telecoms, networking and broadcast systems.
Housed in a compact 1U high enclosure, the modules can be used as individual units or rack-mounted where up to five can be paralleled or used in an N+1 redundant configuration.
Powersolve is able to supply fully configured 19in rack power systems capable of providing up to 7500W.
Input voltage is a wide 90 to 264V AC and active power correction is standard.
Depending on input voltage, the modules will give 700/1200W at 12V or 750/1500W at 48V which equates to a power density of up to 21W/in3.
Efficiency levels can be as high as 90%.
Other significant features include hot-swap capability, active current sharing and variable speed fan control.
Some intelligence is built-in to the units with communication via the I2C bus and a high degree of protection is offered against parameters such as overcurrent, over/undervoltage, overtemperature and short circuit conditions.
