The switching power supply JLRS200-A05S12 from Guangzhou JETEKPS Electronics is a 204 W model with a 12 V 17 A output. The product page lists an adjustable output range of 10.2 to 13.8 V, a typical efficiency of 87.5 percent at 230 VAC and a maximum capacitive load of 4000 microfarads. The model belongs to the JLRS200-A05 series, which also includes 5 V, 15 V, 24 V, 36 V and 48 V versions. The page is organized around a specification table, a parameter introduction and a precautions section, so a buyer can compare the electrical figures before requesting a sample.

Output, Adjustment and Efficiency

The rated output is 12 V at 17 A, giving 204 W. The output voltage can be adjusted from 10.2 to 13.8 V, and the typical efficiency at 230 VAC is 87.5 percent. The maximum capacitive load is 4000 microfarads. That figure is useful when the load has a large input capacitor. For the other models in the table, the power rises from 200 W at 5 V to 212.4 W at 36 V, and the efficiency ranges from 87 to 89.5 percent. The page does not give a ripple and noise figure, a line regulation figure or a load regulation figure, so those values should be requested from the datasheet if the load is sensitive. A buyer should also confirm the adjustment method and the factory setting of the output voltage.

Input, Protection and Environment

The page lists an optional input voltage range of 90 to 132 VAC. For DC input, the range is 240 to 370 VDC when the switch is set to the 230 position. The standby power consumption is below 1.5 W at 230 VAC. The operating temperature range is minus 30 to plus 70 degrees Celsius. The power supply includes output short circuit, overcurrent, overvoltage and overtemperature protection. It also has a power-on LED indicator. The page states overvoltage category III compliance with EN 61558 and says the unit meets the requirements for 5,000 m altitude applications. The RoHS directive is also listed.

Mounting and Application Checks

The page describes the product as a switching power supply and places it in the AC-DC power supply group. The company also lists DC-DC isolated and non-isolated converters, AC-DC isolated and non-isolated modules, industrial communication modules and application pages for industrial control, intelligent manufacturing, rail transit platform screen doors, power, firefighting, communications, batteries and new energy. That range is useful when a panel needs more than one power block. The page does not give the case dimensions, the mounting method, the terminal type or the weight, so a mechanical check should be made before the design is fixed. It also does not give an MTBF figure, which is worth requesting for a continuous duty application. A buyer should confirm the derating curve at high temperature and the cooling requirement for the enclosure.

Company and Ordering

The company address on the page is the 4th floor, Lianxinhuihuang Technology Park, No. 6 Jiangdong Street, Yonghe Subdistrict, Huangpu District, Guangzhou, with a factory at No. 20, Shilidian Road, Dazu Industrial Park, Chongqing. The phone number is +86 20-32029929 and the email is jetekps@jetekcn.com. The page also offers a selection section, a download section and a product inquiry form. It does not give a price, a minimum order quantity, a delivery time or a warranty term, so those points should be confirmed in the quotation. It is also worth asking for the datasheet, the certificate for the EN 61558 claim and the RoHS report for the ordered batch.

If you need a switching power supply for an industrial panel, a communication cabinet or another DC load, send us the input voltage, the output voltage and current, the load type, the ambient temperature, the mounting space and the quantity. We will confirm the JLRS200-A05S12 configuration, the protection options and the delivery plan, and we will point out the figures that should be checked against the load and the enclosure. A clear electrical brief at the start is the best way to avoid a supply that has the right power but the wrong adjustment range or protection for the panel.
