HT33 series from invt is an online three-phase UPS with power between 40KVA-120KVA. It is useful for internet service providers (ISPs), internet data center (IDCs), computer centers, server rooms, banks, precise equipment, and so on.

HT33 has a three phase in-and-out system, which supports utility of 380/400/415V, 50/60Hz. It employs online double conversion technology providing load with excellent power quality. All types of loads are accepted. It has high overload capacity. It provides complete digital control with three digital signal processors - IGBT rectifier, inverter, charger. Parallel reliability is improved by the digital circulating current control technology.

HT33 provides a broad range of input voltages, suitable for various applications. The high-performance UPS provides features such as high input power factor, GreenPower technology, and low current THD. The smart battery management system results increased battery lifetime. The smart self-diagnosis function and protection against all kind of faults reduce maintenance. It can store a large amount of records.

Entire maintenance can be done from front, leading to space savings. System dependability is improved by the redundant design of power model fans. The subsystem has a modularized design, which results in simpler field maintenance. It has a high mean time before failure (MBTF) of over 200,000h and low MTTR (mean time to repair) of <0.5h.
