Overview
Operating from a wide input range of 90–264V AC at 50/60Hz, this power supply delivers a stable 24V DC output at up to 0.63A, with a maximum output power of 15W. Its high efficiency (≥86%) ensures reduced energy loss and minimal heat generation, supporting long-term use in control cabinets and automation panels.
The unit includes comprehensive protection features such as overvoltage protection, short-circuit protection, overload protection, and overtemperature shutdown, ensuring safe and uninterrupted operation. The adjustable output (23–25V) allows for fine-tuning based on system needs. Housed in a durable IP20-rated ABS enclosure, it mounts easily on standard TS35 DIN rails and operates reliably in temperatures ranging from -20°C to +60°C.

5. Wiring
- Connect the AC input terminals to mains power: L (Live) and N (Neutral).
- The output terminals V+ and V− supply 24 V DC. Connect V+ to the 24 V input of the device and V− to its GND.
- Use the correct conductor cross-section and double-check polarity to avoid damaging connected devices.
- Example wiring: from power supply to a 24 V device.

6. Functional Diagram
Functional Diagram – System Overview
The diagram shows the internal stages of a switching mode power supply (SMPS) from AC input to regulated DC output.
Block descriptions:
- I/P (Input): AC mains voltage is supplied to the power supply.
- EMI Filter: attenuates conducted and radiated electromagnetic interference and protects downstream components.
- Rectifiers & Filter (primary side): converts AC to DC and smooths the rectified voltage with capacitive filtering.
- Power Switching Stage: a high-frequency switching converter (typically a MOSFET) chops the DC voltage to drive the transformer; switching is controlled by PWM (pulse width modulation).
- Transformer: provides galvanic isolation between input and output and steps the voltage up or down.
- Rectifiers & Filter (secondary side): converts the high-frequency AC from the transformer back to DC and filters ripple and noise. Delivers the output rails +V and –V.
- Detection Circuit: monitors the output voltage and generates the feedback for regulation.
- Control Circuit: processes the feedback and adjusts the switching duty cycle for a stable DC output.
- O.L.P. (Over Load Protection): detects overload or short circuit on the output and limits the current or shuts the converter down.
- O.V.P. (Over Voltage Protection): disables the power supply if the output voltage exceeds the set limit.
