Sincro 24 & 48 VDC DC Alternators (IP23) for telecoms, lighting towers

Sincro 24 & 48 VDC Synchronous Direct Current Alternators (IP23)

Upgrade your power generation systems with Sincro's dedicated range of 24 and 48 VDC direct current alternators. Engineered specifically for DC gen-sets requiring a reliable low voltage supply, these synchronous IP23 alternators serve as the ultimate turn-key solution for Original Equipment Manufacturers (OEMs).

Available in models ranging from 60A up to 800A, these high-efficiency units provide robust power delivery for a wide range of industrial requirements.

Ideal Applications

Built to provide continuous and stable energy, these alternators are perfectly suited for:

• Telecoms: Reliable power for telecommunications infrastructure and hybrid telecom applications.

   

• Lighting Towers: Optimized for efficiently powering low-voltage LED lighting towers.

   

• Battery Charging: High-performance solutions for battery chargers and emergency power backup units.

   

• Industrial & APUs: Ideal for Auxiliary Power Units (APU) and extra-low voltage (ELV) systems used in transportation, construction, and military equipment.

   

Key Technical Features & Advantages

• Integrated Design for Compactness: Featuring an integrated AC/DC rectifier bridge, these alternators offer a highly compact footprint and vastly simplify the mounting and assembly process for gen-sets.

   

• Digital AVR & Voltage Stability: Outfitted with a highly responsive digital AVR (Automatic Voltage Regulator), they maintain a constant 24 VDC or 48 VDC output across a very large operating speed range. The operating output voltage is settable from 22 to 30 VDC or from 46 to 58 VDC.

   

• Superior Efficiency & Savings: High efficiency ranging from 0.75 to 0.85 (depending on the model) eliminates the need for external inverters or stabilizers. This leads to significantly reduced fuel consumption, minimized maintenance demands, and optimized assembling costs.

   

• Exceptionally Low Ripple: Enjoy clean power delivery with a standard ripple factor of < 2% on 9-phase versions (FB and IB models), and < 8% on 3-phase versions (E3 and FT models), ensuring low line disturbance for sensitive electronic equipment.

   

   

• Built-in Safety Protections: Every unit is fully equipped with both current overload protection and underspeed protection as a standard, maximizing the safety and longevity of your equipment.

   

   

• Rugged, IP23 Construction: Rated with an IP23 protection degree and Class F/H insulation, they are built to perform reliably in temperatures ranging from -20°C to +40°C (+55°C with derating).
