EhubAmerica PS1216-RB AC to DC Converter Power Supply AC110V to DC13.8V Car Radio Base Station Marine

The EhubAmerica PS1216-RB is a regulated AC-to-DC bench power supply designed to power car radios, base station radios, and marine radio installations from a standard 110 V AC mains source. By converting AC110V input to a stable DC 13.8 V output at up to 16 A, it replicates the nominal voltage of a 12 V vehicle electrical system, allowing mobile and marine radios to operate from a fixed indoor or shore-power source. The regulated design maintains low ripple voltage to prevent interference with connected radio equipment and surrounding devices. A comprehensive protection suite — covering input over-voltage, output over-voltage with automatic recovery, output over-current with automatic recovery, input phase reversal, and input/output reverse-connection — safeguards both the power supply and the connected radio against wiring errors and abnormal operating conditions. The unit is stated as suitable for 25–50 W radios, making it a practical and reliable bench or rack power source for amateur, commercial, and marine radio operators.

Key features & benefits

• Stable 13.8 V Regulated Output — Delivers DC 13.8 V ±0.2 V at up to 16 A, closely matching the nominal voltage of a vehicle charging system so mobile and marine radios operate within their designed voltage window.
• Low Ripple Voltage — The regulated design minimizes ripple on the DC output line, reducing the risk of audible noise or interference being introduced into the radio's receive and transmit circuits.
• Automatic Over-Voltage Protection with Recovery — If output voltage rises above the normal range the supply automatically cuts output; once voltage returns to normal the 13.8 V output is automatically restored without manual intervention.
• Automatic Over-Current and Short-Circuit Protection — Should output current exceed the 16 A maximum or a short-circuit condition occur, the supply automatically cuts power output and recovers automatically when the fault is cleared.
• Input Over-Voltage Protection — Built-in protection responds to abnormal AC input voltage conditions, helping prevent damage to internal components and connected equipment.
• Input Phase Reversal Protection — If the AC input polarity is reversed the supply stops working automatically, protecting vehicle and marine power systems from damage.
• Reverse-Connection Protection — Incorrect wiring of input or output connections causes the unit to cease operation immediately, protecting both the supply and attached radio equipment from reverse-polarity damage.
• Suited for 25–50 W Radios — The output current and voltage ratings are matched to the typical power demands of 25–50 W mobile, base station, and marine band radios that normally operate from a 13.8 V DC source.
