DC18V-36V to DC13.8V Power Supply

The myVolts DC18V-36V to DC13.8V Power Supply converts a wide DC input range into a stable 13.8V output rated at 45A. It is built as a high-efficiency, high-precision DC conversion regulated supply for vehicle-mounted wireless transmitters such as two-way radios. Over-voltage protection triggers at 16V±1.5V and over-current protection at 11A±1A to protect connected equipment.

Installers running two-way radios from 18V-36V

This unit suits installers who need a regulated 13.8V rail for a walkie-talkie or similar transmitter in a car or truck. The 80% effective rate and 150mVP-P ripple spec support clean operation for sensitive RF gear. Buyers needing an AC-input supply, a different output voltage, or a lower current rating should look at other products.

45A continuous output current

The single specification that decides fit is the 45A output current rating combined with the 13.8V±0.2V output voltage. Verify that your transmitter’s maximum draw stays within this limit and that the 18V-36V input matches your vehicle’s electrical system before purchase.

Perguntas sobre este artigo

How do I install the DC18V-36V input unit in a vehicle and which step is often missed?

Connect the supply between the vehicle DC18V-36V source and the walkie-talkie; the step often missed is confirming the source stays within the 18V to 36V window before powering on.

What maintenance or replacement will the supply need later?

No user-serviceable parts are listed; the metal case and 80% effective rate imply heat is managed passively, so only periodic dust removal from the 13 x 8.5 x 5 cm enclosure is practical.

What limit appears first during sustained transmit use?

The output over-current protection triggers at 11A±1A, well below the 45A rating, so that protection circuit will trip before thermal limits are reached.
