Galvanic isolated industrial double-conversion Hyundai UPS is the best choice for large offices where high reliability is required. This UPS can be connected in parallel, providing the customer with up to 720KVA concentrated UPS. An optional advanced efficiency optimizer circuit can bring you 98% of efficiency during 30 years lifetime.
Till now, the general approach of existing equipment that, in stable conditions of the mains electricity, aimed to increase the efficiency of UPS has consisted in transforming a double-conversion UPS into a passive-standby operation (off-line) UPS.
For the first time, we offer an optional efficiency optimizer, based on rapidswitching circuits and voltage-stabilizer, that, in the same stable conditions, transforms the UPS, instead of passive-standby operation (off-line), into a UPS with a line-interactive performance.
