Sourced and supplied across Saudi Arabia
A stabiliser corrects voltage and stores no energy, and that boundary is worth stating plainly because it is the source of most mismatched purchases: it will hold a sagging feeder at the right voltage all day and it will do nothing whatever during an outage. Buy it for the symptom of a long or heavily loaded supply — lights dimming when a large motor starts, equipment tripping on undervoltage at the end of a run, a site at the far end of a rural feeder — and buy a UPS if the load must survive a break. Two properties then decide the model. The input window is how far the incoming voltage may wander while the output stays within tolerance, and it should be measured on site rather than assumed. Correction speed is the second: a servo-motor stabiliser is accurate and mechanical and therefore slow, while a static unit responds in a fraction of a cycle, which is what a fast-acting sag needs.
The more of this you send, the closer the first quotation lands.
| Problem observed | Sag, surge, slow drift, or fluctuation when large loads start |
|---|---|
| Measured input range | Actual voltage extremes at the site, measured over a week |
| Required output tolerance | How tight the corrected output must be held |
| Correction speed | Servo for accuracy, static for fast sags |
| Load rating | kVA, with the load type and its starting behaviour |
| Phases | Single or three phase, and whether phases must correct independently |
| Unbalanced load | State if the three phases carry markedly different loads |
| Bypass | Manual or automatic bypass so the load survives a fault in the unit |
| Efficiency and losses | The unit runs continuously — losses are a running cost |
| Enclosure and ambient | IP rating and the real temperature at the installation |
| Noise | Servo units are audible — state if it sits near occupied space |
| Monitoring | Metering, alarm contacts, or a communication interface |
