The device works as it should

I tried the power supply over the weekend and it worked as the device should. I tested old car radios and their functionality. The device will automatically use the appropriate amount of current with the 12V setting, even if the settings are at maximum. A very neat and stylish rough surface on the body itself and the connectors can be unscrewed, so that you can replace them with fixed wires, for example, if you want to measure a device without pike jaw connectors. The discount was good, I paid about €90 for the device. I recommend it, clever, cheap and simple to use for hobby use.

Bench power supply S-LS-98
Instruction manual

Product Description

Reliable laboratory power supply with up to 90 W

The laboratory power supply S-LS-98 is specialised to supply external devices with direct current, whereby current strength and current voltage are individually adjustable. It is also equipped with a 5-V USB interface. The benchtop power supply was primarily designed for professional use in the industrial sector, in laboratories, in telecommunications, for workshops with electronic devices as well as for production facilities and testing institutes. The linear technology results in low residual ripple and low noise.

The current values are always optimally adjusted with the lab power supply from Stamos Soldering

Due to the large LED display, you can easily read the set values of the output voltage, current and power at any time. Even when the lighting is bad, the digits are easy to read. In addition, the individual displays are provided with their respective unit abbreviations, so that the current and voltage can be clearly distinguished at any time.

The user-friendly lab power supply can be controlled very easily and conveniently via rotary knobs. The knobs allow for precise adjustment for the desired current from 0 to 30 V DC and output voltage from 0 to 3 A. During the adjustment, you can check the respective values on the large LED display and easily adapt them to your needs. When the laboratory power supply operates as a constant voltage source (CV), the device switches automatically to constant current mode (CA) as soon as the set load limit is reached. This prevents damage to the connected devices.

With the adjustable laboratory power supply, you get an device with a high safety standard: The device has an overcurrent protection (OCP), an overload protection (OPP), a current limitation and a special overheating protection (OTP). The integrated fan adapts to the internal temperature conditions and ensures optimal cooling. These precautions guarantee a safe operation of the power supply, even with intensive and permanent use. The device also has a summing alarm, which informs you about safety deficiencies.

Non-slip rubber feet additionally ensure a secure stand of the device and also protect the footprint from unwanted scratches. With the lab power supply from Stamos Soldering, you get a thoroughly professional device for the individual direct current supply of various external equipment.
