F.Fonseca presents the HT11 Series of INVT Online UPS

F.Fonseca, INVT's representative in Portugal, offers the HT11 series of online UPS for tower mounting, with models ranging from 6 kVA to 20 kVA. 

This UPS is designed to protect electro-sensitive devices against power problems such as failures, over/under voltage, transients and voltage spikes. The HT11 series features DSP control technology, online double conversion topology, and high efficiency up to 95%. The output power factor is equal to 1 (kVA=kW) and uses 3-level technology for compatibility with complex loads. The number of batteries can be configured on the LCD, with intelligent charging management to maximise battery life. 

The design is compact, with high power density, and allows parallel operation of up to 4 units. It includes an optional 12A charger for large capacity batteries. Technical specifications include an input voltage range of 50%-125% (220 VAC/230 VAC/240 VAC), input frequency of 40 Hz-70 Hz, and output voltage of 220 V/230 V/240 V with ± 1% or ± 2% regulation. THDu (Total Harmonic Distortion) is ≤1% with full linear load and ≤5% with non-linear load. 

The system efficiency reaches up to 93.5% in normal mode and up to 98% in eco mode, with a noise level below 48dB at less than 70% load. Interfaces include RS232 and EPO as standard, with options for SNMP, USB, dry contact (AS400), parallel kit, eco kit and external battery cable. 

Applications for the HT11 series include airports, data centres, office and industrial buildings, schools, commercial spaces, hospitals, hotels, emergency systems, telecommunications and transport.
