Online UPS and isolation transformers for pharma plants
In a GMP environment a power event is not only a downtime cost — it is a deviation, an investigation and potentially a lost batch.
What actually goes wrong
A pharmaceutical site has to prove that conditions were maintained, not just that the plant kept running. A stability chamber that drifted for twenty minutes, an HPLC run interrupted mid-sequence, a lyophiliser that lost vacuum — each generates a deviation report, and the investigation costs more than the power event did. Meanwhile the QC lab’s analysers need a noise floor that most industrial supplies cannot deliver.
What to get right
The decisions on this list are the ones that are expensive to change after the equipment is on site.
Qualification documentation
IQ/OQ protocols and traceable calibration certificates for commissioning instruments. Ask for these at the quotation stage — retrofitting the paperwork later is painful.
Laboratory noise floor
HPLC, GC-MS and spectrophotometers are microvolt-signal instruments. Ultra isolation with over 100 dB attenuation is standard specification.
Environmental chambers
Stability chambers and cold rooms need continuity across the DG start window or the excursion becomes a deviation.
Clean room HVAC
Differential pressure has to be maintained. AHU control supplies belong on the no-break side even when the fan motors do not.
Data integrity
Under 21 CFR Part 11 expectations, servers and instrument workstations losing power mid-write is a data integrity issue, not just an IT one.
Audit-ready maintenance
Preventive maintenance and battery test records get inspected. Our AMC reports are formatted to be handed over directly.
What we supply into this sector
Online UPS
True double-conversion topology from 3 kVA to 200 kVA across three series, with single-phase or three-phase output. Zero transfer time, pure sine output held to ±1%, and up to 96% efficiency. Built and load-tested in Pune.
Isolation Transformer
Galvanic separation between supply and load, with electrostatic shielding that attenuates common-mode noise by 100 dB or better. 1 kVA to 500 kVA.
Servo Voltage Stabilizer
5 kVA to 500 kVA, air or oil cooled, correcting to ±1% output. The right first fix when the MIDC feeder swings all day and the equipment keeps tripping on undervoltage.
Automatic Transfer Switch (ATS)
The supply you are on fails, and the load moves to the one that has not — with nobody at the panel. 10 A to 150 A, single phase and three phase.
Through the life of the machine
Pharmaceutical & Life Sciences — questions we get asked
Anything not covered here, call us — most of it is faster to answer on the phone.
Do you provide IQ/OQ documentation for pharma installations?
Yes, on request at the quotation stage. Installation and operational qualification protocols, calibration certificates traceable to national standards for the test instruments, and commissioning records in a format that goes into your validation file. It needs to be scoped up front, not added afterwards.
Which pharma loads should be on UPS rather than DG?
Anything where a fifteen-second break creates a deviation: stability chambers, environmental monitoring, instrument workstations and servers, clean room pressure control, and any process mid-cycle such as a lyophiliser. Utilities and general lighting can sit on the DG side.
We will do the load grading with you
Site survey, load list and a single-line diagram before anything is quoted. That is where the specification is actually decided.
