With a proportional electric actuator and a magnetic speed sensor it controls engine speed in isochronous mode (±0.25% or better) or in droop (1–5%).\n\nIts main features are the STARTING FUEL and SPEED RAMPING adjustments: starting fuel can be set from almost closed to nearly full during cranking, and after start the speed rises from IDLE to the governed speed at a controlled rate, which keeps exhaust smoke down before the engine reaches operating speed. It also has an overspeed shutdown circuit, a crank termination circuit with N.O./N.C. relay contacts (10 A), adjustable droop and idle, and inputs for accessories.\n\nThe actuator output switches at about 500 Hz and gives up to 10 A continuous at 25 °C. It is compatible with all GAC proportional actuators except the ACB2001.","full_description_ar":"الـ ESD5550 من سلسلة كروت السرعة ESD5550/5570. مع اكتواتور كهربائي تناسبي وحساس سرعة مغناطيسي تتحكم في سرعة المحرك بسرعة ثابتة (±0.25% أو أفضل) أو بالـ Droop من 1 إلى 5%.\n\nأهم ما يميزها ضبط وقود البدء (STARTING FUEL) وتدرّج السرعة (SPEED RAMPING): يُضبط وقود البدء من شبه مقفول إلى شبه مفتوح أثناء المارش، وبعد الدوران ترتفع السرعة من السرعة البطيئة إلى سرعة التشغيل بمعدل محسوب، فيقل الدخان قبل الوصول لسرعة التشغيل. فيها كمان دائرة فصل عند زيادة السرعة (Overspeed)، ودائرة فصل المارش بريلاي بنقاط مفتوحة ومقفولة (10 أمبير)، وضبط للـ Droop والسرعة البطيئة، ومداخل لكروت إضافية.\n\nخرج الاكتواتور يعمل بتقطيع حوالي 500 هرتز ويعطي حتى 10 أمبير مستمر عند 25 °م. متوافقة مع كل اكتواتورات GAC التناسبية ما عدا ACB2001.","key_features":["Isochronous ±0.25% or better;
