TLD 409-E-CUP – 90 kVA Diesel Ground Power Unit (GPU)

The TLD 409-E-CUP provides a continuous output of 90 kVA at 400 Hz and includes a 28.5V DC transformer rectifier, making it well-suited for both AC and DC aircraft systems. This dual output capability supports a wide range of aircraft that require simultaneous AC and DC power, including those with complex onboard avionics or startup requirements.

Yes, the 409-E-CUP is equipped with a Tier 4 Final diesel engine, ensuring compliance with the latest EPA emissions regulations. This environmentally conscious design not only helps reduce your carbon footprint but also aligns with airport and military requirements for cleaner-burning ground support equipment.

With a 46-gallon fuel tank, the TLD 409-E-CUP offers a runtime of approximately 8 hours under standard operating conditions. This makes it suitable for day-long support operations without the need for frequent refueling.

This GPU is ideal for narrow-body and regional aircraft, supporting both civil and military applications. Its 400 Hz and 28.5 VDC output allows compatibility with a wide range of aircraft models that use AC systems for avionics and DC systems for battery charging and engine starts.

Yes, the 409-E-CUP is built on a cart-mounted platform and features fifth-wheel steering with a no-drop towbar brake. This design allows for safe and easy towing across busy ramps and hangars, making positioning the unit more efficient, even in tight or crowded environments.

The unit is designed with low-noise technology, making it ideal for airports or service areas with strict noise limitations. The sound-reducing enclosure and Tier 4 engine help keep operational decibels to a minimum, enhancing both safety and comfort for ground crews.

Routine maintenance includes engine oil and filter changes, fuel system checks, and cooling system inspections, all of which are simplified by the unit’s easy-access panels and modular components. The Tier 4 Final engine also has extended maintenance intervals compared to older models, helping reduce downtime.

Yes, the TLD 409-E-CUP is engineered to operate reliably in harsh environmental conditions, including high heat, humidity, and freezing temperatures. It’s widely used at military outposts and commercial airfields worldwide, proving its reliability in diverse climates.

Absolutely! The GPU includes solid-state voltage regulation to ensure consistent and safe power delivery to aircraft systems. This protects sensitive avionics from surges or fluctuations and contributes to safer maintenance and startup operations.

The 28.5V DC output is supplied via a transformer rectifier (TR) unit, which converts part of the AC output to DC. This allows simultaneous support of aircraft systems that require both types of power, a common need during ground maintenance and preflight configurations.

Yes, it’s designed with standardized interfaces and durable construction that match industry norms, making it a seamless addition to most commercial and military ground support fleets. It also integrates well with telematics systems for real-time operational monitoring.
