Review LAB VOLT Vintage Compact Dc Power Supply Nos

The LAB-VOLT AR-401 and AR-101 power supplies are versatile and high-performance units designed for various laboratory and educational applications. These DC power supplies come in a compact, benchtop design, making them ideal for use in confined laboratory spaces.

The AR-401 model is a constant voltage and constant current power supply, capable of delivering a maximum output voltage of 40V and a maximum output current of 1A. It features a front-panel rotary voltage control and a front-panel sliding current control, allowing for precise adjustment of output levels. The AR-401 also includes overvoltage, overcurrent, and short-circuit protection to ensure safe operation.

The AR-101 power supply, on the other hand, is a constant voltage power supply with a maximum output voltage of 100V and a maximum output current of 1A. It offers a front-panel rotary voltage control for fine-tuning output levels. Similar to the AR-401, the AR-101 includes overvoltage, overcurrent, and short-circuit protection.

Both power supplies feature a front-panel LCD display that shows output voltage, output current, and the status of protective functions. They also include a front-panel selector switch to select the output voltage range and a rear-panel IEC power inlet with a detachable cord for easy replacement or upgrades.

Constructed from high-quality materials, these power supplies are built to withstand the rigors of laboratory use while ensuring accurate and stable output levels. The front panels are made from a durable, scratch-resistant material, while the rear panels are shielded to reduce electromagnetic interference.

Additionally, the AR-401 and AR-101 power supplies come with NPT threaded output jacks, allowing for easy connection to various laboratory equipment using standard banana plugs or test leads. The supplies also include a front-panel accessory socket for connecting an optional auxiliary power supply or a fan for improved cooling during heavy loads.

In summary, the LAB-VOLT AR-401 and AR-101 power supplies are versatile and reliable units suitable for a wide range of laboratory and educational applications. They offer precise output control, robust protection features, and a compact benchtop design, making them excellent investments for any laboratory or educational setting.
