24/48 VDC alternators for telecoms, lighting towers and extra-low voltage DC applications
In the world of power generation, Sincro has been one of the first Europebased manufacturers in developing a dedicated range of DC alternators specifically made for DC generating sets in the UK, reports UKPN.
supplying reliable and efficient energy from 60A to 800A. The DC 3-phase or 9-phase alternators derive from AC synchronous versions (E3, FT, FB, IB). DC gen-sets are used in direct-current applications. These applications include telecommunications, lighting towers and all kinds of extra-low voltage (ELV)
T
used in industrial equipment, construction, military &
(auxiliary power units), LED lighting towers (Light Emitting Diode lamps), battery chargers, emergency power back up units, power supply for monitoring of safety warnings, alarms and control devices (rail- ways, traffic-lights etc).
Hybrid power systems are also included (reducing CO2 and heat emissions, fossil fuel consumption, and noise), more and more common in supplying everyday’s life. Sincro’s DC alternators are equipped with a dedicated DIGITAL AVR specifically designed to protect the gensets against any current overload. It also maintains a constant nominal output voltage of 24 VDC or 48 VDC within a
he current Sincro DC range includes 28 models made in Italy, working at 24 VDC or 48 VDC, in 2 or 4 pole versions, brushless or brushes,
large operating speed range (variable speed).
This provides:
- Nominal speed: 1500 RPM (4 poles/50Hz) or 3000 RPM (2 poles/50Hz) - Variable speed working: 1400÷2300 RPM (4 pole models), 2800÷4200 RPM (2 pole models).
systems transportation, such as: APU
The voltage set-point can be obtained through: a proper setting of the AVR (trimmer), or an external potentiometer, or an outer controller.
Sincro DC alternators ensure low ripple levels, in accordance with standards requiring low line disturbance on the equipment. In Sincro DC alternators, the rectifier is directly integrated in the alternator,
offering the
genset OEMs a turnkey solution with no need for an external rectifier and its related management. Sincro’s R&D’s team and factory flexibility means that all Sincro DC models can be produced in a custom version. With this approach, Sincro offers products which retain a very low ripple level (9-phase windings, integrated filters etc).
