Product Details

The NewMar 115-12-20A is a heavy-duty linear DC power supply designed for marine and commercial vessel applications where reliable 12-volt power is critical. This rugged unit delivers 20 amps intermittent (8 amps continuous) output, making it ideal for powering communication equipment, navigation systems, and other essential 12V electronics in harsh marine environments.

Key Features:

  • Linear circuit design provides pure, noise-free DC output with minimal ripple (40mV peak-to-peak)
  • Exceptional voltage regulation maintains output within 1% under all rated line and load conditions
  • Polyurethane conformal-coated circuit board for moisture and corrosion resistance
  • Heavy-duty powder-coated aluminum heat sink case with integral shock mounts
  • Large heat sink fins extract and dissipate heat for cool, efficient operation
  • Comprehensive protection: overvoltage, current limiting (105% of intermittent rating), thermal overload, and input/output fusing
  • Dual voltage input: selectable 115/230 VAC operation (105-125 or 210-250 VAC, 50-60 Hz)
  • Front panel terminal block and heavy-duty mounting flange for easy installation

Technical Specifications:

  • Output Voltage: 13.6 VDC (internally adjustable 12.6-14.5 VDC)
  • Output Current: 20A intermittent (20 minutes max, 20% duty cycle) / 8A continuous (24/7 operation)
  • Input Current: 5.5A @ 115VAC, 2.5A @ 230VAC
  • Regulation: 1% line and load at 110-125/220-250 VAC input
  • Operating Temperature: 0-50°C (derate linearly from 100% @ 40°C to 50% @ 50°C)
  • Thermal shutdown at 85°C case temperature
  • Dimensions: 5.7" H × 4.8" W × 16.3" D
  • Weight: 20 lbs (9.1 kg)

Optional Features Available:

  • Battery charger modification
  • Custom output voltage adjustment within 12.6-14.5 VDC range
  • ERC transfer relay for automatic backup battery switchover during power failure

Built to withstand the demanding conditions of commercial marine operations, this power supply combines proven linear technology with robust construction for years of reliable service.

I only gave them a 3 star raring on their shipping because I went on their site on Tuesday and the order said it had not been shipped. On Wednesday I received my shipment. The left hand needs to figure out what the right hand is doing. Other than that, GREAT
