GST40A12-P1J 12V 3.34A 40W Switching Power Supply with Universal 90-264VAC Input, for Consumer Electronics/Telecom/Industrial Equipment

The GST40A12-P1J industrial switching power supply provides 12V DC output with 3.34A continuous current (0-3.34A adjustable range), delivering 40W rated power for professional applications. Engineered with 89.5% typical efficiency, this Class I power adapter minimizes energy waste while maintaining ±1% line regulation and ±3% load regulation accuracy. Its universal 90-264VAC input accommodates global voltage fluctuations with 47-63Hz frequency compatibility, supported by robust 35A/115VAC and 65A/230VAC cold-start capabilities. The unit features multiple protection mechanisms: automatic recovery from short-circuit (SCP), overload (105-150% range), and over-voltage (OVP) conditions, backed by <0.75mA leakage current protection at 240VAC. Technical specifications include 1000ms startup time with 50ms rise time at full load, 120mVp-p ripple noise, and 50ms/15ms holdup time at 230VAC/115VAC respectively. The 94V-0 flame-retardant plastic housing ensures safety compliance with LPS standards, while the integrated LED power indicator and 3-year warranty guarantee reliable operation. Certified for CE, RoHS, and international energy regulations (DoE Level VI, EU ErP Lot 7), this adapter is ideal for powering telecom infrastructure, industrial control systems, POS terminals, and professional AV equipment requiring stable 12V DC power with industrial-grade reliability.
