Overview
The Cisco PWR-ME3KX-AC is a power supply unit designed to support a wide range of input voltages and operational environments, making it a versatile choice for network hardware. It operates efficiently across AC input voltages from 100 to 240VAC and frequencies from 50 to 60Hz, accommodating global electrical standards. Additionally, it supports DC input voltages from 18V to 32VDC and 36V to 72VDC, broadening its compatibility with various DC power environments.
This power supply ensures continuous operation in diverse temperature and altitude conditions. At altitudes up to 1000 feet (300m), it can function normally within a temperature range of 0ºC to 50ºC. The operational temperature range adjusts with altitude, allowing for normal operation from 0ºC to 45ºC at up to 6000 feet (1800m) and from 0ºC to 40ºC at altitudes up to 10,000 feet (3000m). For short-term exceptional conditions, the unit can handle temperatures up to 60ºC at 1000 feet (300m), 55ºC at 6000 feet (1800m), and 50ºC at 10,000 feet (3000m), ensuring reliability even under extreme conditions.
Humidity levels within the operational environment are also a consideration, with the unit functioning optimally in 5% to 95% non-condensing relative humidity. This wide range ensures that the power supply can operate efficiently in both dry and humid conditions without condensation risk, which could damage the internal components.
The Cisco PWR-ME3KX-AC is designed with front-to-back air flow direction, incorporating a fan module to maintain optimal internal temperatures and ensure stable operation across various environmental conditions. This design choice is crucial for maintaining efficiency and prolonging the lifespan of the power supply by preventing overheating.
In terms of acoustic noise, the unit operates with a typical sound pressure level (LpA) of 43 dB and can go up to a maximum of 46 dB. The sound power level (LwA) is typically 5.4 Bel, with a maximum of 5.6 Bel, making it a relatively quiet power supply option for environments where noise levels are a concern.
For storage, the power supply is capable of withstanding temperatures ranging from -25ºC to 70ºC at an altitude of up to 15,000 feet (4572m), ensuring that it can be safely stored in a wide range of conditions without affecting its performance or reliability.
