The SANTAK Castle C1K is a 1000VA / 900W online UPS for servers, network equipment and sensitive office devices that need clean, uninterrupted power. Unlike an offline UPS, an online UPS powers your equipment continuously through its inverter, so there is no switch-over gap when the mains fails.
It accepts a wide 100-300 VAC input, provides 220/230/240VAC output and offers 15-20 minutes of backup with its standard battery. That makes it a solid choice for small server rooms, ISP points of presence and office network racks.
Q: What is the difference between online and offline UPS?
A: An online UPS always powers your devices through its inverter, so output stays clean and there is no gap during a cut. An offline UPS switches to battery only when power fails.
Q: How long is the backup time?
A: The standard backup is 15-20 minutes, depending on the load you connect.
Q: Can it handle low voltage areas?
A: Yes, it accepts input from 100 to 300 VAC, which covers very low voltage conditions.
