Pacific Aerials P5027M 24/12V Switchmode Converter

Pacific Aerials 24V to 12V DC-DC Switchmode Converter with Switched Output

The Pacific Aerials P5027M is an advanced, high-efficiency 24V DC to 12V DC switchmode power converter designed to power sensitive 12V communications, navigation, and marine electronics from 24V DC vessel power systems. Delivering 10 Amperes of continuous power (14A peak), the P5027M features an integrated 12V / 100mA auxiliary switched accessory output to trigger secondary control circuits, remote relays, or equipment wake-up signals.

Housed in an anodized T6063 marine-grade aluminum enclosure, the P5027M is engineered for high-vibration, high-humidity marine and commercial vehicle applications. Its high-frequency switchmode topology ensures over 90% operational efficiency while maintaining low RF electromagnetic interference (EMC/RFI) across sensitive marine VHF, AIS, and HF radio frequencies.

Key Features

• 12V / 100mA Switched Accessory Output: Provides a dedicated switched signal line to automatically trigger remote relays or power state switches.

• 10A Continuous / 14A Peak Output: Provides clean, regulated 13.2V DC power for marine electronics, stereo systems, and communication gear.

• High-Efficiency Switchmode Topology: >90% efficiency minimizes heat dissipation and standby power draw.

• Low-RFI / EMC Compliant Design: Specially filtered to prevent radio frequency interference on VHF, AIS, and cellular bands.

• Comprehensive Fault Protection: Built-in safeguards against output short circuits, overcurrent, thermal overload, input overvoltage, and reverse polarity.
