## Summary description

The Vertiv Geist VA4U21A0 is a monitored power distribution unit with 12 AC outlets, designed for single-phase use. It features a 1U rack capacity and supports various network protocols for monitoring current, power, and voltage. With a nominal input voltage of 100-240 V and a maximum current of 20 A, it is UL & c-UL Listed and complies with IEC 62368-1 standards.

## Long description

The Vertiv Geist Rack Transfer Switch VA4U21A0 is a monitored 1U rack power distribution unit (rPDU) for single-phase installations. It provides automatic backup power to single-corded devices by switching from the main source to a secondary source within 4–8 milliseconds. The unit supports multiple input voltages (120V/208V/230V) and a maximum current of 16A/20A, and includes twelve combination C13/C19 outlets plus two C20 inlets for a power capacity up to 3.6 kW depending on voltage and current configuration. Monitoring and status are shown on the integrated Vertiv Geist Next-Generation IMD with a 128x128 high-visibility LCD and an internal orientation sensor for horizontal or vertical mounting. The device includes enhanced security (secure boot), a redundant power-sharing port for connecting two IMDs, and is individually tested and certified to applicable standards.
Advantages
The rPDU delivers fast automatic transfer to a secondary power source to maintain continuity for single-corded equipment. Integrated monitoring via the Next-Generation IMD provides clear, real-time power and status information on a high-contrast LCD. Orientation-aware sensing simplifies installation in either horizontal or vertical positions. Built-in security features and individual testing support reliable operation in datacenter and network environments, while certifications (CE, RoHS, IEC compliance) confirm regulatory conformity.
Suitable for
Rack-mounted servers and network switches with single power cords
Edge racks and small data centers requiring compact 1U power distribution
Environments needing basic automatic source transfer for redundancy

How to use
Install the VA4U21A0 into a 1U rack space and connect the primary and secondary power sources to the C20 inlets. Mount the unit horizontally or vertically; the internal sensor will adjust the IMD display orientation automatically. Connect single-corded devices to the combination C13/C19 outlets. Use the IMD display to monitor voltage, current and power data and verify correct operation. Ensure the redundant power-sharing port is set up if a paired IMD is used for shared backup functionality.
Usage recommendations
Verify input voltage and current configuration before commissioning, and confirm compatibility with connected equipment. Follow site grounding and electrical codes. Periodically check the IMD display and test source transfer behavior during scheduled maintenance to ensure expected redundancy performance.
