Preen APS Series
Solid State Power Conditioner
Not every power quality problem calls for the same fix. Where the issue is fast voltage fluctuation — sags, surges, and rapid variation that disrupts sensitive equipment — a solid-state power conditioner using electronic compensation responds in milliseconds, correcting the output before the fluctuation reaches the load. Preen's APS series is built for exactly this: fast-response voltage regulation holding ±1-4% output regulation with a response time of 4ms or less per correction step.
That speed matters most in applications where even a brief voltage excursion causes a problem — SMT production lines, where voltage instability can affect process consistency; medical equipment, where power quality has direct safety implications; telecom stations, where continuous stable power is operationally critical; and EMC labs, where the test environment's own power quality needs to be clean enough not to interfere with the measurements being made. Efficiency reaches up to 98% at full load, and the range covers single-phase (1-100kVA) and three-phase (10-300kVA) configurations, with overload capability up to 200% for 10 seconds or 500% for 50 milliseconds covering brief transient demand spikes.
For sites without dedicated indoor equipment space — telecom base stations, outdoor enclosures, and other remote installations — a customised outdoor cabinet rated to IP54 is available, extending the same fast-response conditioning capability to locations where a standard indoor-rated unit wouldn't be appropriate.
