VDRS-40-24 is an AC-DC DIN rail power supply designed for industrial and commercial applications requiring regulated 24 V DC output. It features universal input voltage capability (88–264 Vac or 124–370 Vdc) and delivers up to 40.8 W continuous power with 1.7 A maximum output current and 84% efficiency. The unit incorporates comprehensive protection mechanisms including over-voltage (latch-off mode at 115–150%), over-load (constant current limiting with automatic recovery), over-temperature, and short-circuit protection, along with isolation voltage of 3,000 Vac (input to output) and 1,500 Vac (input to case). With UL1310, UL508, and TUV safety approvals, RoHS compliance, and output ripple and noise of 120 mVp-p at full load, this supply is well-suited for DIN rail mounting in control systems, automation equipment, and industrial instrumentation where reliable, compact power conversion is essential.
