What does this DIN rail power supply do?
This unit is designed to convert incoming power into a regulated 24 Vdc output for industrial equipment. The SDP 4-24-100LT is commonly suited to control panels, automation assemblies and instrumentation where stable DC power is required.
What output does it provide?
It provides a nominal 24 Vdc output and features an adjustable output range of 24 to 28 Vdc, giving extra flexibility when matching the supply to connected devices.
How much current can it deliver?
This model is rated for up to 3.8 A output current. When sizing a power supply, it is sensible to allow some headroom for start-up demand and continuous loading.
Is the output adjustable?
Yes. The unit includes a front-panel adjustment potentiometer, allowing the output to be set within the published 24 to 28 Vdc range.
Can it cope with difficult start-up loads?
Yes. It is designed with PowerBoost overload behaviour to help start industrial loads such as relays, solenoids, motors and DC-DC converters that can cause standard power supplies to fold back or shut down.
What protection features are included?
The design includes overvoltage protection, short-circuit protection and continuous short-circuit capability. This makes it a practical choice for demanding industrial environments where dependable DC power is important.
How is it mounted in a panel?
It is made for DIN rail installation and is intended to snap on without tools. Published series information also indicates compatibility with TS35/7.5 and TS35/15 rail formats.
How much space does it take up?
The published dimensions for this model are 75 mm high, 72.5 mm wide and 96.7 mm deep. That footprint can be useful when planning panel layout and spacing.
What operating environment is it intended for?
This power supply series is intended for industrial use and is rated for operation from -10°C to +70°C. Full output is available up to +60°C, with derating above that point.
Does it include a visual status indicator?
Yes. The series includes a DC status indicator, allowing users to quickly check whether the output is present and the unit is operating normally.
What type of electrical connections does it use?
It uses screw terminal connections, which are widely used in industrial panels for secure field wiring.
Where is this type of power supply commonly used?
Typical applications include industrial control, process control, machine control, building automation and instrumentation. The SDP 4-24-100LT is aimed at installations needing a compact DIN rail DC supply for panel-based equipment.
