National Instruments 782857-01 PXI Programmable power supply. 

The part number 782857-01 from National Instruments is the identifying part number for the PXIe-4112 PXI Programmable power supply. This 60 Watts power supply module is designed specifically for the PXI series of modules featuring two isolated output channels capable of outputting 60 Volts DC with a maximum output current of 1 Ampere. This power supply module has a resolution of 2 mA for programming the output voltage and measurement. 

The 782857-01 power supply has a voltage accuracy rating of 0.12% + 55 mV, while the current accuracy is 0.01% + 500 μA. To measure voltage losses directly at the load terminals, the 782857-01 module features remote sensing which helps this module by ensuring precise delivery of voltage to the connected load. For voltage regulation, the maximum deviation is 0.01% + 300 μV, and for current regulation the maximum deviation is 0.01% + 300 nA, making this power supply a great choice for accurate power delivery with minimum deviation. 

The power supply module is designed to feature low ripple and noise with a value of less than 24 mV peak-to-peak and more than 4 mV RMS for voltage output. To ensure quick stabilization of the output voltage level, the 782857-01 transient response time is 40 ms for full resistive loads and 100 ms for no load conditions. This quick stabilization feature allows this module to respond accordingly and ensure safe power transmission to the load, protecting both the power supply module and the load from over and under voltage conditions. 

This power supply module is designed to be operated in an environment with a temperature between 0 degrees Celsius and 40 degrees Celsius and can be stored in an environment with an ambient temperature between -40 degrees Celsius and 70 degrees Celsius to prevent the module from degrading over time. The 782857-01is designed according to the EMC standards as well as meets compliance standards including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1 for electrical equipment safety, making this power supply an ideal choice for use in environments that require high safety standards.
