5 best lab power supplies

This laboratory block has received a lot of positive reviews, where it is often called the best value for money. The sites on which these comments are published relate to the repair of cell phones, that is, the device has received special distribution among electronics repairmen, which is not surprising, since it is unlikely to be suitable for laboratory purposes.

Ya Xun PS-1502DD is a single-channel instrument, the connection diagram of which is extremely simple and clear. Voltage range up to 15 watts, at 1-3 amperes of current. And the ripple was set at 3 units. There are no complicated tuning models here, and all parameters are output by four resistors. Fine tuning allows you to output four-digit values ​​\u200b\u200bto the channel, although this is not so important. But the main aspect for which the model is praised is the price. Ya Xun PS-1502DD is the cheapest power supply, and interestingly, this did not affect its quality in any way. The point is the low popularity of the brand, otherwise we have a decent option, perfectly coping with their tasks.

Despite the ubiquity of electronics, analog devices are still popular, and we have a laboratory power supply that does not have a liquid crystal display. There are two dial indicators: one measures the voltage in the output range from 0 to 15, the other ampere from 1 to 3 units. The connection and control scheme is extremely simple. All interaction is performed using a single resistor located on the front panel, and the limiting ripple is set at around 3 mV.

There are no complicated buttons and this can be called both a minus and a plus. Everything depends on the tasks. The device is single-channel, and as accurate as possible, but it will not work to display a thousandth of a volt on it. From this we conclude that the unit has only a name from the laboratory, and in fact it is perfect only for home craftsmen or owners of small repair shops that repair and test various electronics that do not require extreme accuracy.

Despite its name, the laboratory power supply is not only used in scientific stations. It is often used by home craftsmen when testing devices that require non-standard voltage. Often, it does not make sense to buy an expensive and complex tool, and there is an opportunity to save money by purchasing this model. This is the best price we could find. At least, it is such in relation to the quality of the device.

Element 1502DD is a full-fledged single-channel power supply that can upgrade the mains voltage with an accuracy of a hundredth. Not the best indicator, but quite sufficient for most devices. Thousandths are used very rarely, and even less often in radio electronics. The voltage power is from 0-15, and the maximum ripple is only 1-3 mV. In general, a great option for those who are fond of electronics and repair various devices. Cheap and made by a big-name manufacturer that is often praised online. And here you should not be embarrassed that the brand is Chinese. Even the most popular laboratory block companies come from this country, which does not prevent them from becoming the best.

The lab power supply is often a very large piece of equipment, for which you need to find a separate place on or near the table. If you are also facing this problem, be sure to check out this product, the main advantage of which is its compactness and vertical form factor. The block will easily find a place on the table and will not interfere, but this alone cannot be an argument for placement in our rating. In addition to compactness, we highlight the connection diagram. This is a two-channel instrument that outputs power to the nearest thousandth. The indicator is very good, if not the best.

Each channel has its own LCD display, and tuning is done using a single rotating resistor. No complicated wiring diagrams and a huge number of buttons. Just apply power and display the voltage you need in the range of 0-18 watts and 0-3 amperes with a ripple level of no more than 0.5mV. Even the instruction is not needed, although it is included in the kit and even translated into Russian. The price will also please you - the most attractive price tag on the market, at least in relation to the quality of the product, about which there are a lot of positive reviews on the net.

Before us is a full-fledged laboratory power supply with many fine settings and the ability to obtain other data on the voltage, both input and output.The device works on only one channel, which can be called a disadvantage, but there is an opportunity not only to set the necessary parameters, but also to remember them, writing them into 500 memory cells.

Also, the advantages include a convenient digital display that allows you to fine-tune the parameters to the hundredth. Not without drawbacks. First, the rather high cost. The market for laboratory units is not so extensive, but there are models that are much cheaper. Secondly, a complex connection scheme, or rather, a large number of settings that can confuse the user. The interface is not intuitive, and you will have to figure out how the tool works on your own. Fortunately, the kit comes with instructions in Russian. In general, the main argument that allowed us to place this power supply in such an honorable place in the rating is the technical side. The scheme is complex, but definitely reliable and of high quality.
