NewMar 115-24-35CD 24V DC Power Supply 35 Amp 115/230V Input

The NewMar 115-24-35CD is a heavy-duty linear DC power supply designed for powering 24-volt communication and navigation equipment on commercial vessels where reliability is critical. This rugged unit delivers 35 amps maximum output with pure, noise-free DC power thanks to its proven linear circuit design.

Key Features:

• Dual voltage input: 115/230 VAC selectable (105-125/210-250 VAC range), 50-60 Hz
• 24.5 VDC nominal output, internally adjustable from 21-27.5 VDC
• 35 amp maximum output capacity (10A intermittent, 4A continuous rating)
• Thermally activated cooling fan for enhanced heat dissipation
• Excellent regulation maintaining output voltage within 1% under all rated line and load conditions
• Ultra-low ripple: 70mV peak-to-peak
• Polyurethane conformal coated PC board for moisture and corrosion resistance
• Heavy-duty powder-coated aluminum heat sink case with integral shock mounts
• Comprehensive protection: overvoltage, current limiting (105% of intermittent rating), thermal overload, and input/output fusing

Specifications:

• Input Current: 5.5A @ 115V / 2.5A @ 230V maximum
• Operating Temperature: 0-65°C (derate linearly from 100% @ 50°C to 50% @ 65°C)
• Thermal shutdown at 85°C case temperature
• Duty Cycle - Intermittent: 20 minutes max, 20% duty / Continuous: 24/7 operation
• Front panel terminal block with heavy-duty mounting flange

This marine-grade power supply is built to survive hostile environments with its corrosion-resistant construction and conformal-coated electronics. Optional modifications available include battery charger configuration, custom output voltage adjustment, and transfer relay for backup battery failover (ERC option).
