The National Instruments 784767-01, also known as the RMX-4126, is a highly versatile 1U full-width programmable DC power supply designed for rack mounting. This single-channel unit delivers a total power output of 1500 W and can provide voltage levels up to 230 VDC with a maximum current of 20 A, making it suitable for diverse applications in industrial and laboratory testing environments. The 784767-01 features multiple user interaction modes, allowing for intuitive manual operation via its front panel or automated control through built-in interfaces including USB, LAN, RS232, and analog connections.

With an impressive transient response time of less than 7 ms and tight regulation capabilities—± 4 mV line regulation and ± 25 mV load regulation—the power supply ensures stable output under varying load conditions and external fluctuations. It supports input voltage ranges from 85 to 265 VAC and an input frequency of 47 to 63 Hz, boasting a power factor of 0.99 at 100 V and 0.97 at 200 V. The device has a maximum input power of 2200 VA and an efficiency rating of 74% or higher. For enhanced operational reliability, the 784767-01 features a hold-up time of at least 20 ms during power interruptions and integrates comprehensive protection mechanisms against overvoltage, overcurrent, and overheating, which safeguard both the device and connected equipment. With a weight of 9.0 kg (19.84 lb) and supported by a warranty of 2 to 3 years, the National Instruments 784767-01 is an ideal solution for long-term continuous operations in rigorous testing scenarios.
