MEAN WELL HDR-30-24 36 W 24 V DIN Rail Power Supply

24V Power for a Well-Planned Control Cabinet The HDR-30-24 supplies 24 V DC at up to 1.5 A for suitable control, automation and industrial networking equipment. Its 36 W rated output and DIN rail mounting make it a practical component for building a dedicated equipment power system. The 35 mm-wide enclosure fits TS-35/7.5 or TS-35/15 mounting rails. Natural convection cooling avoids an internal fan, while adjustable output, a power indicator and built-in protection functions help integrate the supply into a properly designed cabinet. Highlights DC Output 24 V DC nominal output; up to 1.5 A and 36 W. Adjustable output range 21.6–29 V DC. 89% typical efficiency under specified test conditions. Cabinet Installation 35 mm enclosure width. TS-35/7.5 or TS-35/15 DIN rail mounting. Fanless cooling by natural air convection. Operation and Protection −30°C to 70°C operation with load derating. Power-on LED indicator. Protection against short circuit, overload and overvoltage. Key Features Size the Supply for the Connected Load The nominal 24 V output supports suitable equipment drawing up to 1.5 A, within the 36 W rated capacity and derating limits. Allow for startup demand, cable voltage drop and the load’s permitted voltage range when designing the system. A matching voltage and connector alone do not establish compatibility. Keep Cabinet Space Under Control A 35 mm-wide body mounts on TS-35/7.5 or TS-35/15 DIN rail, helping organise the power supply beside control and networking equipment. Maintain the manufacturer’s ventilation and separation clearances. The rail and the surrounding protective cabinet form part of the installation rather than a plug-in desktop setup. Adjust the Output Within Its Rated Range The output can be adjusted through 21.6–29 V DC to suit an approved system design. Confirm the connected equipment’s voltage limits before adjustment and keep the load within the rated power. Adjustment is intended for commissioning; it is not automatic detection of the voltage a connected device needs. Use Fanless Cooling With Proper Ventilation Natural convection cooling keeps the supply free of an internal cooling fan. The specified operating range is −30°C to 70°C, subject to the manufacturer’s load-derating curves and installation conditions. Leave the required airflow space and consider the cabinet’s actual internal temperature when selecting the supply. Build Protection Into the Equipment Design Built-in protection covers short circuit, overload and overvoltage. These functions support the power stage, while suitable upstream protection, correct cable sizing and safe terminal wiring remain part of the complete installation. The power indicator provides a simple local check of the DC supply. Match the Power Supply to the System Use the HDR-30-24 with equipment that accepts its nominal voltage, current capacity and wiring arrangement. Industrial switches may require a particular supply voltage to achieve their stated PoE budget. Check the exact host requirements and total load rather than assuming the supply’s full rating becomes usable PoE power. Compatible Models D-Link DIS-210G-06 and DIS-210G-12. Confirm the required input voltage, load and terminal wiring for the exact switch configuration before installation. This is a DIN rail power supply; the switch, DIN rail and installation are separate. Summary The HDR-30-24 combines a 24 V DC output with DIN rail mounting, fanless cooling and practical protection functions. Select it as part of a correctly rated power system, with suitable wiring, ventilation and equipment compatibility, for an orderly control or industrial networking installation. Frequently Asked Questions What Is the Nominal Output?ExpandCollapse The nominal output is 24 V DC, with up to 1.5 A and 36 W under the specified operating conditions. The adjustable range is 21.6–29 V DC; adjustment does not increase the maximum rated power. Does It Plug Directly Into a Wall Socket?ExpandCollapse No. This is a terminal-wired DIN rail power-supply component. It needs suitable mains wiring, a protective installation and competent electrical installation. A wall plug, mains lead and cabinet are not provided by the power supply itself. Is the DIN Rail Included?ExpandCollapse The unit mounts on a suitable TS-35/7.5 or TS-35/15 rail. Plan the mounting rail, enclosure, wiring and required ventilation space separately. A rail shown in a product photograph illustrates mounting. Can It Be Used With Any Industrial PoE Switch?ExpandCollapse No. Confirm the exact switch’s DC voltage range, startup demand and required power budget. This supply provides nominal 24 V DC; its wattage is not an automatic guarantee of the switch’s usable PoE output. Does It Keep Equipment Running During a Power Cut?ExpandCollapse No. It converts the input supply to DC and does not contain a battery or provide UPS backup. A separately designed backup system is needed if the application must run through a power cut. Can It Deliver Full Power at the Highest Temperature?ExpandCollapse Not necessarily. The operating-temperature range is subject to the manufacturer’s derating curve, input voltage and installation conditions. Size the supply for the actual enclosure temperature, airflow clearance and continuous load. 더 보기
