NewMar 115-12-35CD 12V 35 Amp DC Power Supply 115/230VAC

The NewMar 115-12-35CD is a super-rugged DC power supply designed for powering 12-volt communication and navigation equipment onboard commercial vessels where reliability is critical. This linear power supply delivers pure, noise-free DC output with exceptional regulation, making it ideal for sensitive marine electronics in harsh environments.

Key Features:

• Linear circuit design provides clean, noise-free 13.6 VDC output (adjustable 12.6-14.5 VDC)
• Excellent regulation: output voltage maintained within 1% under all rated line and load conditions
• Dual voltage input: 115/230 VAC selectable (105-125/210-250 VAC range), 50-60 Hz
• 35 amp maximum output (both continuous and intermittent ratings)
• Thermally activated cooling fan for efficient heat management
• Polyurethane conformal-coated PC board resists moisture and corrosion
• Heavy-duty powder-coated aluminum heat sink case with integral shock mounts
• Comprehensive protection: overvoltage, current limiting (105% of rating), thermal overload, and input/output fusing
• Low ripple: 40mV peak-to-peak at rated input voltage

Technical Specifications:

• Output: 13.6 VDC, 35 amps continuous/intermittent
• Input Current: 7.5A @ 115VAC / 3.5A @ 230VAC maximum
• Operating Temperature: 0-65°C (derate linearly from 100% @ 50°C to 50% @ 65°C)
• Thermal shutdown at 85°C case temperature
• Front panel terminal block for easy wiring
• Heavy-duty mounting flange included

Built for the demanding marine environment, this power supply can be modified for use as a battery charger and offers optional transfer relay (ERC) for automatic battery backup during power failure. The rugged construction and proven linear design ensure long service life even in hostile conditions.
