In Central Asia, where grid fluctuations are frequent, an EPC company specialising in hospital infrastructure chose Ortea to ensure stable and safe power supply. Two SIRIUS 1600-20 electromechanical voltage stabilisers were supplied to protect critical medical equipment, reducing hidden costs and improving operational continuity.
WHY UNSTABLE VOLTAGE IS A REAL RISK IN HOSPITALS
In healthcare facilities, even small voltage fluctuations can lead to:
- Shutdowns in operating rooms, ICUs and diagnostics
- Artefacts and repeated scans in CT/MRI/angiography exams
- Laboratory equipment malfunctions
- Stress on UPS systems and reduced battery life
- Data loss or resets on clinical IT/IoT systems
- Overheating in HVAC and lighting systems
- False alarms and degraded power quality in wards
THE ORTEA SOLUTION: 2 SIRIUS 1600-20 VOLTAGE STABILISERS
To meet the EPC’s specifications, we supplied 2 SIRIUS 1600-20 electromechanical voltage stabilisers (optimised version, digital control per phase).
Main technical data:
- Rated power: 1600 kVA, efficiency >98%
- Input range: ±20% (320-480 V)
- Output accuracy: ±0.5% at 400 V
- Fast regulation (18 ms/V) and 100% unbalanced load tolerance
- Integrated protection: SPD Class I/II, supercapacitor for grid return
- 10″ touch HMI, Ethernet/USB/MODBUS communication, IP21 indoor enclosure
INTEGRATED TPK (TOTAL PROTECTION KIT)
Each unit is equipped with a TPK (Total Protection Kit) consisting of:
- 2500 A (3P) automatic input switch.
- 2500 A (3P) automatic interlocked bypass.
- 2500 A (3P) motorised automatic output switch.

CONTINUED TRUST: A LOYAL CLIENT
The EPC had already entrusted Ortea with a major project for a hospital in Turkmenistan. This new order confirms their continued trust in Ortea’s reliability in the medical sector.
WHY CHOOSE ORTEA FOR HOSPITALS
Ortea Next ensures:
- Real voltage stability, even with unbalanced loads
- Full protection for sensitive medical equipment
- End-to-end support from design to after-sales
- Proven experience in international hospital projects
EXPECTED BENEFITS FOR THE HOSPITAL
The implementation of SIRIUS stabilisers leads to:
- Operational continuity in critical departments and reduction in unscheduled downtime.
- Consistent diagnostic quality (fewer artefacts, fewer repetitions/exposures).
- Asset protection (fewer power supply/UPS failures, longer service life).
- OPEX reduction (less waste, less corrective maintenance, fewer penalties).
FAQ ON CHOOSING STABILISERS AS A POWER QUALITY SOLUTION IN HOSPITALS
- Why use stabilisers if I already have UPS and generators?
UPS and generators cover sags/interruptions; they do not correct slow variations and imbalances. The stabiliser maintains the voltage within ±0.5% even when the mains fluctuate, lightening the load on the UPS and reducing battery cycles. - Is per-phase regulation necessary?
In hospitals, loads are very unbalanced (diagnostics, HVAC, lifts). Independent per-phase regulation prevents overvoltage/undervoltage on individual lines, protecting sensitive devices. - What does TPK add in practice?
It integrates protection and control (input/output switches, interlocked bypass), speeds up installation and allows safe maintenance without interrupting service. - What is the impact on operating costs?
Stable voltage reduces failures, repeat tests and emergency interventions on the UPS: benefits that are reflected in lower OPEX and greater department availability.
