Best selling Lab power supply
Here's a ranking of the best products in this category. To give you a quick overview, we've also added some key information about the products.
1. Peaktech P 6226 Switched-mode power supply unit
This laboratory power supply offers an adjustable DC voltage output of 0 - 30 V or 0 - 10 A. The current and voltage settings are made via digital potentiometers, allowing both values to be adjusted even when the output sockets are turned off. By pressing the respective rotary knob for current or voltage, the setting resolution can be switched from 10 mA to 100 mA or from 10 mV to 1 V. To ensure safe measurements, there is a button on the front of the PeakTech 6226 that is used to control the output of the voltage. The display also indicates when the output is active. With the CV and CC functions, the voltages and currents can be set to constant values that do not change when a load is connected. These features make the PeakTech 6226 a remarkable companion for any hobbyist electronics enthusiast as well as for any specialist.

2. Peaktech P 6227 Switched-mode power supply unit
This newly developed laboratory power supply offers an adjustable 0...60V or 0...6A DC main output with a maximum continuous power of 150W. For developers, this lab power supply offers two switchable USB outputs with their own LCD display with voltage and current values. If you use a load up to 2.5A, you can regulate the output voltage up to 60V. If you want to use a higher current up to 6A, regulate the load to a maximum of 25V. Of course, all levels in between are also adjustable, such as 30V/5A, 40V/3.7A or 50V/3A. The current and voltage setting is also done when the output is switched off. By pressing the rotary knob for current or voltage, the setting resolution can be switched fine/coarse from 1mA to 100mA or 10mV to 1V. Due to the high range of functions and the simple operation with the best price/performance ratio, this laboratory power supply is ideal for the training, hobby, developer and service area.

3. Peaktech P 6225 A Switched-mode power supply unit
This laboratory power supply offers a variable DC voltage output of 0 - 30 V or 0 - 5 A. The current and voltage settings are made using digital potentiometers, allowing both values to be adjusted even when the output sockets are turned off. By pressing the respective rotary knob for current or voltage, the setting resolution can be switched from 10 mA to 100 mA or from 10 mV to 1 V. To ensure safe measurement, there is a button on the front of the PeakTech 6225 A that is used to control the output voltage on and off. The display also indicates when the output is active. Another notable feature is the CV (Constant Voltage) and CC (Constant Current) function of the power supply. With this function, the voltages and currents can be set to constant values that do not change when a load is connected. These features make the PeakTech 6225 A an outstanding companion for any hobbyist in electronics, as well as for any specialist.

4. Peaktech P 6080 A Linear laboratory power supply unit
The new PeakTech 6080 A is a linear regulated laboratory power supply with passive cooling and high resolution digital display (1mA and 10mV). This model features coarse/fine control via separate potentiometers for precise selection of current and voltage settings. Due to the linear technology used, this model does not generate any high-frequency interference and a safety transformer in accordance with EN-61558-2-6 has also been used, which outputs a safety extra-low voltage (SELV) to ensure the greatest possible user safety. This power supply unit in modern design has been specially designed for the service and training sector and convinces with its excellent price/performance ratio.

5. RND 320-KA3005P
