ZY_UHBD-5W is a wide-voltage input isolation power supply series module developed by Guangzhou Zhiyuan Electronics. It has high conversion efficiency, good high and low temperature characteristics, strong capacitive load capacity, and short circuit protection functions. International standard pin-out, UL94-V0 flame-retardant package, natural cooling, no need for external heat sinks, no need for external components can be used directly, and can be directly welded on the PCB board. Simple connection, it is your ideal front-stage power solution.
The ZY_UHBD-5W series from ZLG offers a wide input voltage range and high isolation, making it suitable for industrial control, data communication, and step‑by‑step power control systems. The modules feature PWM regulation, short‑circuit protection, and UL94‑V0 flame‑retardant packaging.
Key specifications include selectable output voltages (3.3 V, 5 V, 12 V, 15 V, 24 V), typical output accuracy of ±1 %, operating temperature from –40 °C to +85 °C, and a switching frequency of 300 kHz. Pin definitions, mechanical dimensions, and recommended circuit connections are provided for easy integration. This manual is written in Chinese.
