FAQ
What is the power rating of the Mean Well ES-SU3K-RHB?
The ES-SU3K-RHB is rated for 3KVA / 3KW output. It also has an output power factor of 1, which means its kVA and kW ratings are aligned for full real-power delivery.
What input voltage range does the ES-SU3K-RHB support?
This model supports an ultra-wide AC input voltage range of 110V to 300Vac at 50% load, and 160V to 300Vac at 100% load. That wide range can help it handle unstable mains conditions more effectively than narrower-input UPS models.
Is the ES-SU3K-RHB suitable for business-critical equipment that needs clean power?
Yes, this online UPS is designed for applications where power quality matters. It specifies input power factor of at least 0.99, input current harmonic distortion of 5% or less, and output harmonic distortion as low as 2% THD for linear loads.
Can the Mean Well ES-SU3K-RHB work with generator-backed power systems?
Yes, the ES-SU3K-RHB supports connection to fuel generators. That makes it a practical option for sites that use generator support during outages or in locations with less stable utility power.
Does this UPS support multiple output voltage and frequency options?
Yes, the ES-SU3K-RHB supports output voltage selections of 200, 208, 220, 230, and 240Vac. It also includes a 50Hz/60Hz frequency conversion mode, which can help match equipment requirements across different operating environments.
What operating environment is this model designed for?
The specified operating temperature range is 0°C to 40°C. Buyers should make sure the installation environment stays within that range for normal operation and expected performance.
