What is the difference between an online UPS and a line-interactive UPS?
An online (double-conversion) UPS powers your load from its inverter all the time, so there is zero transfer time and the output stays clean even when mains voltage swings. A line-interactive UPS passes mains through and only switches to battery during a cut. For CNC machines, servers, medical and lab equipment, an online UPS is the safer choice.
Do I need a servo stabilizer if I already have a UPS?
Often, yes. A UPS covers outages; a servo voltage stabilizer corrects long periods of high or low voltage on the whole line, including motors, compressors and machines that are not on the UPS. In industrial estates with frequent voltage fluctuation, the two work together.
How do I size a UPS for my factory or office?
Add up the running load in kW or kVA of the equipment to protect, allow headroom for starting current and future expansion (usually 20 to 25 percent), then choose the battery backup time you need. Share your load list with us and our engineer will recommend the rating and battery bank.
Is Unitech an authorized Vertiv dealer?
Yes. Unitech Power Systems is an authorized channel partner for Vertiv (Liebert) and also supplies Delta, Eaton and Fuji Electric, alongside our own Unitech-make UPS and servo stabilizers.

Yes. We handle installation and commissioning, warranty service, annual maintenance contracts (AMC) and battery maintenance contracts for the systems we supply.
