Sinepower ground power unit

Sinepower designs and manufactures high-quality and efficient electrical power products for the aviation, aeronautical and maritime sectors.

The company offers environmentally friendly products that are easy to use and maintain, designed to meet the client’s requirements.

Ground power unit systems for aircrafts

SinePower’s ground power unit (GPU) systems guarantee a safe, efficient and high-quality energy supply to all aircrafts in hangars and / or ramp aircraft maintenance.

Sinepower’s GPUs feature power factor correction to guarantee a precise sinusoidal input current from 25% to 150% load, and a low total harmonic distortion of current (THDi) of less than 1.5%.
The company’s static frequency converters convert the source power with a specific input voltage and frequency into a different output voltage and frequency, depending on the client’s requirements.
Sinepower offers 28V DC solid-state ground power supplies suitable for 300A-600A continuous and 1,200A-2,400A peak loads.
Sinepower's electronic voltage regulators are used in power quality applications where enhanced speed and performance make it an alternative to a mechanical equivalent.
Sinepower’s lift inverters supply power to emergency evacuation elevators when the mains fails.
Sinepower’s GPU&DC units were designed with Powerfactor correction to guarantee a perfect sinusoidal input current from 25% to 150% load and a low THDi (<1.5%). The 28VDC offers solid-state ground power supplies that range from 300A continuous to 1,200A peak load, and 600A continuous to 2,400A peak load.
Sinepower offers 28VDC solid-state ground power supplies that range from 800A continuous to 1,500A peak loads for up to ten seconds.

Available as stationary or mobile units, the company’s GPUs offer various outputs, ranging from 30kVA up to 90kVA.

Eco-friendly static frequency converters for military operations

Sinepower’s SINE33I-SFC static frequency converter units provide clean, efficient and secure electrical power supplies by converting grid electricity to the appropriate load frequency.

The company’s converters guarantee a sinusoidal voltage wave form with less than 3% total harmonic distortion (THD) to supply the output load.

Sinepower SFCs are designed for shore-to-ship and ship-to-shore, as well as civil and military applications.

High-current rectifiers with IGBT and FET technology

Sinepower’s latest high-current rectifier can be used with the company’s GPUs, SFCs or by itself.

It comprises a durable AC-DC/DC-DC converter using field-effect transistor (FET) and insulated-gate bipolar transistor (IGBT) technology, and high-frequency isolation transformers to offer aircrafts a reliable 28V DC supply and crank current.

The high-current rectifier can withstand inrush currents of up to 2,400A and its high-frequency technology allows reduced size and accurate regulation.

Electronic voltage regulators for reliable power supply at airports

Sinepower’s electronic voltage regulators (EVRs) provide a stabilised power supply solution where there are frequent voltage fluctuations, as well as guarantee stable voltage to sensitive loads.

The company’s EVRs combine voltage conditioning and stabilisation, promoting an optimal output sinusoidal wave shape, an instant response time (lower than half a cycle / 10ms), independent regulation by phase, and high levels of efficiency, inrush and current capabilities.

Emergency lift inverters for public buildings

Sinepower’s lift inverters (LIs) supply emergency evacuation energy when there is a power failure.

They are suitable for all types of public buildings such as airports, schools, libraries, hospitals and offices.

ISO-certified quality management systems

Sinepower undergoes an extensive evaluation process, including document reviews, process mapping and quality management, as well as internal and external audits to achieve their ISO 9001: 2008 certification, the worldwide standard for quality management systems and practices.

The company’s GPUs, SFCs and quality management system are certified by TUV.
