| region_notes | The only APsystems specification table reachable for this model is the one marked 'For APAC' on global.apsystems.com, so the product is created at region APAC and the figures below are APAC figures. This is NOT the EU product: the APsystems EMEA DS3D page states a 1800 W maximum output while the APAC datasheet prints 2000 W, so the EU variant has a different electrical specification and was record |
