National Instruments 784767-01 Programmable Power Supply Device

The National Instruments 784767-01 is a 1U full-width single channel rack mountable DC power supply that delivers a total power output of 1500 W. The model is also known as RMX-4126. This power supply is highly versatile and offers a broad range of voltage and current limits. The device can provide up to 230 VDC or 20 A. The power supply's capacity to handle large power requirements across a wide voltage and current range makes it suitable for various industrial and laboratory testing environments.

The 784767-01 model comes equipped with multiple user interaction modes that allow both manual and automated control. For manual users, the front panel provides buttons and knobs for easy operation while remote and automated users can take advantage of the built in interfaces such as USB, LAN, RS232 and analog control options. 
This power supply features line and load regulation that ensures stable output even when external conditions fluctuate. It has a transient response time of 7 ms or less which guarantees rapid recovery from load changes. The power supply also offers a ripple noise of 120 mV (p-p) and a line regulation of ± 4 mV. 

The 784767-01 power supply supports voltage between 85 and 265 VAC with an input frequency of 47 to 63 Hz. It has a power factor of 0.99 at 100 V input and 0.97 at 200 V input. The maximum input power is 2200 VA with a minimum efficiency of 74%. The hold-up time for power interruption is at least 20 ms that provides reliable operation even under power fluctuation conditions. The NI 784767-01 module includes protection features like overvoltage, overcurrent, and overheat protection. It can automatically shut down or limit its output in case of abnormal conditions by protecting both the device and the connected equipment. These features make it highly reliable for long-term, continuous operations in testing environments. The device also features tight regulation capabilities that ensure stable voltage and current outputs even under varying load conditions. Line regulation is rated at ± 25 mV for voltage, and load regulation is at ±25 mV.
