  • TypeAT
  • Stable 13.8V output protects sensitive radio gear
  • Wide 18V-36V input suits varied vehicle electrical systems
  • Over-voltage and over-current safeguards prevent equipment damage
  • Compact 13 x 8.5 x 5 cm metal housing fits tight installs
  • 45A continuous current delivers reliable power for demanding transmitters

Compact DC power supply for mobile radio

This myVolts unit converts a DC18V-36V vehicle input to a stable DC13.8V±0.2V output rated at 45A. It is built for two-way radio installations that demand clean, regulated power in a small metal enclosure. The 80% effective rate and 150mVP-P ripple keep transmitted audio clear.

Replaces bulky linear supplies in vehicle installs

The wide input range tolerates 18V to 36V systems without a separate step-down converter, and the 11A±1A over-current plus 16V±1.5V over-voltage protections guard the radio from transients. The jump is worth it when space behind the dash is tight and a 13 * 8.5 * 5 cm footprint matters.

Fits behind dash panels with minimal wiring

The silver metal case measures 5.1 * 3.3 * 2.0in and weighs 488g, so it mounts on a flat surface with two screws and needs only heavy-gauge DC leads to the battery and a short feed to the radio. It frees up the cigarette-lighter socket and removes the need for an external voltage regulator.

商品問答

What are the exact dimensions of the power supply so I can confirm it fits my vehicle mounting space?

The unit measures 13 x 8.5 x 5 cm (5.1 x 3.3 x 2.0 in) and weighs approximately 488 g, allowing you to verify clearance in your chosen mounting location.

How do I wire the DC 18 V–36 V input correctly, and what polarity mistake should I avoid?

Connect the supply to a DC 18 V–36 V source observing the marked polarity; reversing the input leads can trigger the protection circuits or damage the converter.

When should I expect to replace the unit based on its protection thresholds and efficiency?

The 80 % efficient converter includes over-voltage protection at 16 V ±1.5 V and over-current protection at 11 A ±1 A; if either threshold is repeatedly reached, internal components may degrade and the unit should be replaced.
