Power Adapter Gamber-Johnson ET60/65 Universal 60W Black

The Gamber-Johnson ET60/65 Universal 60W Power Adapter is a DC/DC converter that provides a regulated 12.4 V output from a 12–32 V DC input. The adapter filters input voltage spikes and surges and includes electrical isolation between input and output to prevent ground loops and to allow the negative output of the source to be used as a positive reference when required. Its rugged black aluminum housing and built-in protections make it suitable for demanding vehicle and industrial tablet installations.

Advantages

Electrical isolation removes ground-loop issues and enables flexible reference configurations. The adapter offers multiple protection mechanisms—short-circuit protection, over-current protection and internal over-temperature protection—with automatic restart after fault removal. Low/high input voltage disconnect protects the connected device from out-of-range supply voltages. The compact, durable aluminum enclosure is designed for reliable use in harsh environments.

Suitable for

• Powering vehicle or industrial tablets that require a stable 12.4 V DC supply
• Environments with noisy or fluctuating 12–32 V DC inputs (e.g., automotive, marine, construction equipment)
• Installations where ground isolation is needed to prevent ground loops

Key specifications

• Input voltage range: 12–32 V DC
• Regulated output voltage: 12.4 V DC
• Output power: 60 W
• Enclosure: rugged black aluminum housing
• Protections: output short-circuit protection, over-current protection, internal over-temperature protection, low/high input disconnect, automatic restart after 10 s
• Power supply type: universal DC/DC converter

How to use

Connect the adapter to a suitable 12–32 V DC source according to the installation instructions for your tablet or vehicle system, ensuring correct polarity and secure connections. Mount the adapter in a location that allows adequate cooling and protects it from direct exposure to moisture where possible. If the adapter enters a fault state due to over-current, short circuit, or over-temperature, remove the fault condition; the unit will automatically attempt restart after approximately 10 seconds.

Recommendations

For reliable operation, verify that the tablet’s power requirements match the adapter’s 12.4 V / 60 W output and ensure proper ventilation of the aluminum housing. Use the adapter within the specified 12–32 V input range and follow vehicle or equipment wiring best practices to maintain isolation and prevent unintended ground connections.
