The National Instruments 785343-01 Power Distribution Unit (PDU), also known as the RMX-10051, is an efficient solution for power distribution within test rack systems, including PXI chassis, RAID storage, and human-machine interfaces. Designed to facilitate a controlled and staggered power-up sequence, this unit effectively mitigates potential power surges, thereby protecting sensitive devices during startup. The incorporated Emergency Power Off (EPO) feature enhances operational safety, allowing users to quickly and safely terminate power in emergencies.

With an input voltage range of 200 V to 208 V and compatibility for both 50 Hz and 60 Hz frequency, the 785343-01 is equipped to handle diverse energy requirements. To bolster system integrity, built-in circuit breakers safeguard the PDU and connected equipment from overcurrent situations. Additionally, the unit employs forced hardware delays to manage power distribution across groups of outlets, ensuring safe sequencing during initialization. This PDU supports a three-phase power input, optimizing power efficiency for high-demand devices and accommodating both AC and DC output for a variety of standard and specialized equipment.

Featuring IEC 60309 ABL Sursum S51530 connectors alongside multiple 10 A and 16 A rated AC output receptacles, the 785343-01 is versatile enough to power numerous devices seamlessly. Its compact design makes it well-suited for rack installations in data centers and laboratories. Operating reliably at altitudes up to 3000 meters and within a temperature range of 0 °C to 50 °C, the unit is also rated for operational humidity levels between 5% and 85% relative humidity, ensuring dependable performance across a variety of environmental conditions. The 785343-01 comes with a standard non-specific weight and a warranty period of 2 to 3 years, reinforcing its durability and reliability in demanding applications.
