FAQs
What is the runtime on battery backup?
At a 100W load, the BK500EI provides approximately 24 minutes and 20 seconds of backup runtime. Actual runtime will vary depending on the connected load and battery condition.
Can the battery be replaced by users?
Yes, the BK500EI features a user-replaceable battery design. The replacement battery model is the RBC2, allowing for easy maintenance without requiring technician support.
Does this UPS protect data connections?
Yes, the BK500EI includes RJ45 data line protection for telephone, fax, modem and DSL connections, helping safeguard both power and communication systems.
How many devices can I connect to this UPS?
The BK500EI has four IEC C13 outlets: three provide UPS battery backup and one is surge-only. You can connect up to four devices, though actual capacity depends on their combined power consumption not exceeding 300W.
What is the transfer time to battery mode?
The transfer time is 6ms typical and 10ms maximum. This fast switchover ensures minimal disruption to connected equipment during a power failure.
Can this UPS handle voltage fluctuations?
Yes, the BK500EI includes automatic voltage regulation that handles input voltages between 160V and 300V, protecting equipment from damage caused by brownouts and overvoltage conditions.
Is this UPS suitable for server rooms?
The BK500EI is designed for small office and workgroup environments rather than data centres. For server room applications, a larger UPS with greater capacity and rack-mount options is recommended.
