Q
What are the fuel consumption metrics, injection pump mechanics, and continuous duty ratings for this 50kW (62.5 kVA) Weifang generator set?
A
The 50kW / 62.5 kVA generator set is driven by an industrial Weifang 4-cylinder in-line diesel engine engineered for continuous prime power and utility standby service under ISO 8528 standards. The engine utilizes a mechanical in-line fuel injection pump and mechanical speed governing (optional electronic governing available), providing high tolerance to fuel quality variations in developing markets and eliminating the need for specialized electronic ECU diagnostic laptops during field overhauls. Under continuous prime operating loads (75% to 100% variable load), brake-specific fuel consumption (BSFC) averages between 218 and 228 g/kW·h. The integrated base fuel tank is sized to supply 8 to 12 hours of continuous autonomous operation for agricultural pumping stations, small telecommunication towers, and light manufacturing workshops.
Q
What circuit breaker protection, acoustic attenuation, and mobile trailer configurations are available for the 50kW Weifang unit?
A
Under standard 400V/230V 3-phase output (50Hz) or 480V/220V (60Hz), rated full-load operating current is approximately 90 to 95 Amperes. Output protection is handled by an integrated 125A 3-pole thermal-magnetic Molded Case Circuit Breaker (MCCB) calibrated for rapid thermal overload and short-circuit isolation. For outdoor or noise-restricted environments, the unit is available in a weatherproof soundproof canopy that limits operational noise to 68–72 dB(A) at 7 meters using flame-retardant internal acoustic baffles and residential-grade exhaust silencers. For flexible site mobility, the platform can be factory-mounted on a single-axle or dual-axle road trailer chassis equipped with a height-adjustable tow bar, mechanical parking brake, and leaf spring suspension. Control instrumentation utilizes SmartGen or Deep Sea (DSE4520/DSE6020) digital modules supporting dry-contact signaling for automated utility-to-generator transfer via an external ATS.
