Pacific Aerials P5027M - Voltage Reducer 10A with Memory
Product Overview
The Pacific Aerials P5027M is a professional-grade 24V to 12V switchmode voltage reducer featuring memory function and dual independent circuits for operating 12V communications equipment in 24V vehicle electrical systems. This advanced converter delivers 10 amperes output capacity with intelligent memory functionality that retains power state settings across ignition cycles, providing convenient automatic operation for UHF CB radios, two-way communication systems, and mobile electronics in trucks, buses, and commercial vehicles. The dual circuit configuration enables independent power management for multiple devices with separate control and protection.
The P5027M voltage reducer is essential for fleet operators and commercial transport professionals requiring reliable power conversion with enhanced functionality beyond standard converters. The memory feature eliminates manual power cycling of connected equipment, while the dual circuit design provides flexibility for powering multiple devices with independent control. The compact switchmode technology delivers efficient power conversion with minimal heat generation, making it ideal for permanent installations in commercial vehicle cabins where space and thermal management are critical considerations.
Features & Benefits
Memory Function Intelligent memory circuitry retains power state settings across vehicle ignition cycles, automatically restoring previous operating conditions when the vehicle is restarted, eliminating the need to manually power cycle connected communications equipment and improving operational efficiency for commercial drivers.
Dual Independent Circuits Two separate output circuits enable independent power management for multiple 12V devices, providing isolated control and protection for each connected equipment, allowing simultaneous operation of UHF CB radio and accessory devices with independent switching and circuit protection.
24V to 12V Switchmode Conversion Advanced switchmode technology provides efficient voltage reduction from 24V commercial vehicle electrical systems to regulated 12V output, minimizing heat generation and power loss while maintaining stable voltage regulation for sensitive communications equipment operation.
10 Ampere Output Capacity Delivers 10 amperes total output current across both circuits, accommodating power requirements of UHF CB radios, two-way communication systems, and accessory devices including transmit power peaks without voltage drop or performance degradation.
Compact 0.5kg Design Lightweight construction weighing just 500 grams facilitates easy installation in tight mounting locations including cab dashboards, under-seat areas, and equipment racks without requiring reinforced mounting structures or consuming valuable space in commercial vehicle interiors.
12 Month Warranty Coverage Manufacturer-backed 12 month warranty provides confidence in product reliability and quality, protecting investment in power conversion infrastructure for commercial vehicle communication systems with comprehensive warranty support for manufacturing defects.

Installation & Compatibility
The Pacific Aerials P5027M installs between the 24V vehicle power source and 12V communications equipment, typically mounted in accessible locations such as under-dash areas, equipment racks, or behind cab panels. Professional installation by qualified automotive electricians or electronics technicians is strongly recommended to ensure correct polarity connections, adequate fusing on both input and output circuits, proper grounding, and secure mounting in commercial vehicle environments.
The dual circuit configuration allows independent connection of two separate 12V devices, such as a UHF CB radio on circuit one and an accessory device on circuit two. Each circuit can be independently controlled and protected, providing flexibility for complex installation requirements. The memory function automatically restores the previous power state when the vehicle ignition is cycled, eliminating the need to manually power on connected equipment after each vehicle start.
When planning installations, distribute the 10-ampere total capacity appropriately across both circuits based on equipment power requirements. Typical configurations include 5-6 amperes for the primary UHF CB radio circuit and 4-5 amperes for accessory devices. Installation should include appropriate input and output fusing for each circuit, secure wire routing away from heat sources, and proper ventilation around the converter to ensure adequate heat dissipation during operation.
Frequently Asked Questions
Q: What does the memory function do on the P5027M?
A: The memory function retains the power state of connected equipment across vehicle ignition cycles. When you turn off your truck and later restart it, the P5027M automatically restores power to previously active circuits without requiring manual intervention. This eliminates the need to manually power on your UHF CB radio or other communications equipment every time you start the vehicle.
Q: How is the 10-ampere capacity divided between the two circuits?
A: The 10-ampere capacity is shared across both circuits, not 10 amperes per circuit. You need to distribute the total 10-ampere capacity between circuit one and circuit two based on your equipment requirements. For example, you might allocate 6 amperes to a UHF CB radio on circuit one and 4 amperes to accessory devices on circuit two.
Q: Can I use both circuits simultaneously?
A: Yes, both circuits can operate simultaneously as long as the combined current draw does not exceed the 10-ampere total capacity. The dual independent circuits allow separate devices to be powered at the same time with individual control and protection for each circuit.
Q: Is the P5027M compatible with all 12V communications equipment?
A: The P5027M is compatible with most 12V UHF CB radios, two-way communication systems, and mobile electronics that operate within the 10-ampere total capacity. Always verify the current requirements of your specific equipment, including transmit peaks, to ensure operation within the converter's specifications.
Q: Does the 12-month warranty cover installation issues?
A: The 12-month manufacturer warranty covers manufacturing defects in materials and workmanship. Damage caused by incorrect installation, improper use, or exceeding rated specifications is typically not covered. Professional installation is recommended to ensure proper operation and maintain warranty coverage. Consult warranty documentation for specific terms and conditions.
