## Summary description

The HPE gl/xl/vl Switch Redundant Power Supply (J4839A-RFB) provides reliable power with an AC input voltage of 100-240 V and input current of 3.8-8.2 A. Weighing 2.5 kg (5.55 lb) and measuring 200.7 x 160 x 127 mm, it ensures optimal performance and redundancy for your network switches, enhancing uptime and reliability.

## Long description

Compatible with mains voltages of 100–127 VAC and 200–240 VAC, this power-rated device supports operation across common global supply ranges. It is designed to accept input at either lower-voltage (100–127 V) or higher-voltage (200–240 V) ranges and provides stable performance within standard utility frequency bands.
Advantages
This unit accommodates dual-voltage input, enabling use in regions with 100–127 VAC or 200–240 VAC supply without requiring additional converters. It supports standard utility frequencies of 50 Hz and 60 Hz and is rated for maximum currents appropriate to each voltage range, ensuring safe operation when used within specified limits.
Key specifications
Input voltage: 100–127 VAC / 200–240 VAC
Maximum current: 8.2 A (at 100–127 VAC) / 3.8 A (at 200–240 VAC)
Frequency range: 50 Hz / 60 Hz
How to use
Connect the device to an AC mains outlet that matches one of the supported voltage ranges. Verify the local supply frequency is 50 Hz or 60 Hz. Ensure that the connected load does not exceed the maximum current rating for the corresponding voltage range (8.2 A for 100–127 VAC or 3.8 A for 200–240 VAC). If unsure about local wiring or compatibility, consult a qualified electrician.
Recommendations
Use appropriate fusing or circuit protection sized for the maximum current of the applicable voltage range, and confirm compatible plug/adaptor standards for your region before connecting.
