TDK-Lambda HK25A-24 Power Supply

TDK-Lambda HK25A-24 is a compact single-output switching power supply that delivers 24 V DC at up to 1.1 A (about 26.4 W) from an 85–132 VAC mains input. Its 28 × 68 × 95 mm chassis fits easily into space-constrained installations and it weighs around 230 g, making it suitable for automation, instrumentation, and embedded control applications that require a small, reliable 24 V rail. It provides 2 kVAC input-to-FG and 500 VAC output-to-FG isolation with 100 MΩ minimum isolation resistance, and complies with safety standards such as UL60950-1 and CSA C22.2 No. 60950, along with FCC Class B and VCCI-B EMI limits. The unit operates from 0 to +50 °C (storage -30 to +85 °C) and has a ripple/noise specification near 120 mV peak-to-peak, supporting stable DC for sensitive electronics. Efficiency is typically around 80%, and the HK25A-24 supports in-series operation for stacked voltage configurations; it accepts a broad mains frequency range from 47 to 440 Hz, ensuring compatibility with worldwide power systems. The product offers overcurrent and overvoltage protection on its single output rail, and its fixed 24 V output makes it well suited for general automation, instrumentation, and lab equipment that need a compact, dependable 24 V supply.
