DC13.8V 45A Switch-Mode Supply

The myVolts DC13.8V 45A Switch Mode Power Supply converts a DC18V-36V vehicle input into a regulated DC13.8V±0.2V output rated for 45A continuous current. It is built for mobile radio operators who need stable power for two-way transceivers installed in cars or trucks. Over-voltage protection triggers at 16V±1.5V and over-current protection at 11A±1A to shield connected equipment.

Sustained Load Behaviour

The unit delivers up to 45A output with an effective rate of 80% and output ripple voltage of 150mVP-P across the full input range. Protection circuits engage at 11A±1A over-current and 16V±1.5V over-voltage, preventing damage during prolonged transmit cycles. Precise design and strict quality control support consistent regulation during extended operating periods.

Thermals Noise and Power Draw

The metal enclosure measuring 13 * 8.5 * 5 cm and weighing approximately 488g acts as a heatsink for silent, fanless operation. With 80% conversion efficiency, waste heat remains manageable inside a vehicle cabin during normal use. No moving parts mean zero acoustic noise while the supply regulates DC13.8V±0.2V from the DC18V-36V source.
