ARCTIC

ARCTIC 48V to 12V 30A 360W DC Step-Down Converter

SKU CH-46AM-VG2HF

Converts 30–56 V DC input to a fixed 12 V, 30 A, 360 W output with up to 97 % efficiency in an IP68-sealed aluminium housing

  • Converts 48V to stable 12V at 30A for 360W output
  • Up to 97% efficiency at half load reduces energy waste
  • IP68 sealed aluminium housing resists water, dust and shock
  • Five built-in protections with auto-recovery guard against faults
  • Operates from -40 °C to 85 °C for harsh environments

What this converter does

The ARCTIC step-down converter takes a DC input between 30 V and 56 V and delivers a fixed 12 V output at up to 30 A for a continuous 360 W. It is built for golf-cart, truck and marine electrical systems that run on 36 V or 48 V batteries and need to power 12 V accessories such as audio, lighting or monitoring gear.

Fixed 12 V 30 A output

The only specification that decides fit is the non-adjustable 12 V 30 A rating; the unit will not change voltage and cannot supply more than 360 W. Buyers who need a different output voltage, adjustable regulation or higher current must choose another device.

Sustained-load behaviour

At full load the converter runs at 95 % efficiency with a load regulation of 0.2 % and ripple of 200 mVp, while the IP68-sealed aluminium housing relies on free-air convection from -40 °C to 85 °C. Over-temperature, over-current, over-voltage, overload and short-circuit protections auto-recover once conditions return to normal.

Highlights

Questions about this item

What does 360 W mean for my 12 V devices?

The converter can supply up to 30 A at 12 V continuously, so any combination of 12 V loads that stays within 360 W will run reliably.

How does the 30-56 V input range affect charging-system compatibility?

It accepts the full voltage swing of a 48 V nominal battery bank, from 30 V at deep discharge to 56 V at peak charge, without adjustment.

What mounting clearance does the IP68 aluminium case need?

The sealed, fanless case relies on free-air convection, so leave open space around it and do not enclose it in a tight compartment.
