12V 9A Desktop Power Supply for Motorola Radio
The AD MT 3100/DM power supply is designed to transform Motorola GM and DM series mobile radios into fully functional desktop units. With support for autoswitching AC power (85-135V or 170-265V, 47-440Hz), it provides a stable 13.6VDC with a continuous current of up to 9A, equivalent to 108W of power.
The device features a battery backup output (for a 7Ah lead-acid battery), LED indicators to indicate the power source (mains or battery), and an anodized aluminum case with rubber feet to support the radio directly. Includes built-in over-current, over-temperature, transient and internal fuse protection.

PowerVerter 18A 24V-12V isolated
The PowerVerter 18A 24V-12V isolated is a DC-DC voltage converter designed to power 12Vdc equipment from 24Vdc mobile electrical systems, typically found in diesel vehicles and boats. It is part of the PowerVerter range, optimized for high-volume applications on trucks, buses, agricultural vehicles, and marine vehicles.
The isolated version guarantees greater than 400 Vrms isolation between input, output, and case, making it suitable for marine applications. The anodized aluminum and reinforced polycarbonate enclosure offers IP53 protection against dust and splashes, with no ventilation holes or accessible external fuses.
The no-load current draw of less than 15 mA reduces the impact on the vehicle battery, while the three-point Click-n-Fit mounting system simplifies installation even on uneven surfaces. A green LED indicates the presence of the output, making it easy to check. Main Features
- Current 18 A continuous, 22 A intermittent
- Input 24 Vdc nominal, range 17-32 Vdc
- Output 13.6 Vdc +15% -20%
- Typical efficiency 85% for isolated units
- Isolation >400 Vrms between input, output, and case
- Output noise <50 mV peak-to-peak at continuous load
- No-load current <15 mA
- Overcurrent, overtemperature, and transient protection
- Transient protection compliant ISO7637-2
- ESD protection compliant with ISO10605 and ISO14982
- IP53 rating
- Operating temperature range: -25°C to +30°C at full specification, up to +80°C with linear derating
- Dimensions: 217 x 87 x 50 mm
- Weight: 775 g
- CE and automotive E-marking
Non-isolated DC converter 24V to 12V 6A
The Alfatronix PowerVerter PV6s 24V to 12V 6A non-isolated DC converter is part of a complete range of 3A to 30A converters available in isolated or common-ground versions. It is designed to convert 24V DC to 12V DC in high-volume applications on industrial vehicles, buses, construction, forestry, agricultural equipment, and boats.
The PV6s version is non-isolated with common negative and supplies 6A continuously and 10A intermittently. Intermittent current can be delivered for up to 2 minutes followed by 8 minutes of rest. High efficiency contributes to long-term operational reliability. Main Features
- 24 Vdc to 12 Vdc conversion
- 6 A continuous and 10 A intermittent current
- Non-isolated common negative version
- PowerVerter range from 3 A to 30 A
- Intermittent current: 2 minutes ON, 8 minutes OFF
- Overcurrent and overtemperature protection
- Protection against transients and catastrophic failures
- Click-n-Fit clip mounting
- CE and e-Mark certification
