The contact (12–230 V AC \/ 2–30 V DC, 5 mA to 2 A) follows the overload and overvoltage state shown on the front LEDs, and the 1.5 A short-circuit limit protects the line.\u003c\/p\u003e\n\u003cp\u003eThe supply accepts 180–264 V AC or 240–250 V DC, runs at 87 % efficiency with only 2.9 W dissipation, keeps the bus between 28 and 31 V across all outputs and offers several reset modes from the front. It occupies 4 DIN modules (72 mm) and needs no ETS application.\u003c\/p\u003e\n\u003cp\u003eThe signalling contact is typically wired to a digital input of the building management system or to an alarm module so that bus overload or overvoltage is reported immediately; it can also drive a panel indicator lamp. The DC input option allows the unit to run from a battery-backed 240 to 250 V DC distribution in installations with central backup power. Installation is by a licensed electrician on a dedicated breaker, with the KNX output wired through the standard red\/black bus terminal.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e640 mA total on all outputs, bus voltage 28–31 V DC SELV, integrated choke\u003c\/li\u003e\n\u003cli\u003eMains input 180–264 V AC or 240–250 V DC\u003c\/li\u003e\n\u003cli\u003eSignalling contact 12–230 V AC \/ 2–30 V DC, 5 mA–2 A for overload\/overvoltage reporting\u003c\/li\u003e\n\u003cli\u003eShort-circuit current limit 1.5 A\u003c\/li\u003e\n\u003cli\u003eEfficiency 87 %, dissipation 2.9 W\u003c\/li\u003e\n\u003cli\u003eLEDs for operation, overload and overvoltage; selectable reset modes\u003c\/li\u003e\n\u003cli\u003e4-module (72 mm) DIN housing; no ETS application\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower supply\u003c\/td\u003e\n\u003ctd\u003e180–264 V AC, 50\/60 Hz, or 240–250 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput\u003c\/td\u003e\n\u003ctd\u003eKNX bus 28–31 V DC SELV, 640 mA total on all outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShort-circuit current\u003c\/td\u003e\n\u003ctd\u003e1.5 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEfficiency \/ dissipation\u003c\/td\u003e\n\u003ctd\u003e87 % \/ 2.9 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignalling contact\u003c\/td\u003e\n\u003ctd\u003e12–230 V AC \/ 2–30 V DC; 5 mA–2 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIndicators\u003c\/td\u003e\n\u003ctd\u003eOverload and overvoltage LEDs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN rail, 4 modules (72 mm \/ 2.83 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure\u003c\/td\u003e\n\u003ctd\u003eIP20 (EN 60529)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandards\u003c\/td\u003e\n\u003ctd\u003eEN 61558; EN 50491; LVD 2014\/35\/EU; EMC 2014\/30\/EU\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eKNX certified; CE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eETS application\u003c\/td\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (net)\u003c\/td\u003e\n\u003ctd\u003e0.2 kg (0.44 lb)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part no. \/ GTIN\u003c\/td\u003e\n\u003ctd\u003ePS00E03KNX \/ 8054144521701\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003eWithout signalling contact: PS00D03KNX (640 mA, AUX output) and PS00D04KNX (1280 mA).
