Enterprise Series
A single-phase online UPS for offices, labs and small server rooms — it cleans up unstable mains power and keeps equipment running through an outage.

What it is
The Enterprise Series is COMPACT's intelligent on-line UPS platform, spanning 1 kVA to 20 kVA on a high-frequency IGBT design with a true double-conversion online topology. It is engineered to deliver clean, regulated power wherever the incoming supply cannot be trusted.
One architecture runs from a 1000 VA single-phase tower up to a 20 kVA three-phase-input system. A parallel option is available for high availability, and pan-India sales and service support stands behind every installation.
What it does
True double conversion online
Continuous regulated power regenerated through the rectifier and inverter — the load never sees the raw mains.
High-frequency IGBT design
Latest-generation IGBT technology for a compact footprint and AC-AC efficiency above 90%.
Wide input window
120–300 V AC input range depending on the connected load — fewer transfers to battery on a weak supply.
Low output distortion
Total harmonic distortion held below 3%; pure sine wave output with a 3:1 crest factor.
Parallel & hot-standby
Optional parallel and hot-standby configurations deliver redundancy where downtime is not acceptable.
32-bit microprocessor control
Automatic self-diagnosis for faster fault-finding; optional SNMP for remote monitoring and shutdown.
The engineering value
Conditioned power, not just backup
Because the inverter always runs, spikes, sags, noise and frequency drift on the input are regenerated out before they reach the load — not merely ridden through.
Efficiency that shows on the bill
AC-AC efficiency above 90% keeps running losses and heat down across the 1–20 kVA range.
Scales with the site
Start with a single tower and add a parallel unit later for capacity or redundancy without re-architecting the installation.
Where it fits
Typical applications for this range — not an exhaustive list.
- Servers, network closets and edge IT
- Retail, branch offices and commercial premises
- Medical and diagnostic devices
- Industrial automation and light manufacturing
- Digital printing and laser-cutting machines
- CCTV, access control and building systems
Inside the double-conversion path
Utility power passes through a PFC rectifier and an inverter stage that continuously regenerates a clean sine wave. A static bypass stands ready if the inverter is ever taken out of circuit.
On mains failure the DC bus is held up by the battery with a 0 ms transfer — the inverter output does not interrupt.
The rectifier and inverter run continuously, regenerating a clean output. The battery floats on the DC bus, held in reserve — current is always flowing to the load.

Discrete 1, 2, 3, 6, 10, 11, 15 and 20 kVA ratings are available on this platform. The 11–20 kVA ratings take a three-phase (380 / 400 V ±20%) input while delivering a single-phase output.
