1、Input Voltage: Dual power supply modules are buck type, and a certain voltage difference must be ensured between input and output. In actual test, when the input voltage drops below 5.5, the module turns off the output directly. Recommended for use within 30V input 2、Heat Dissipation: The module is shipped without auxiliary heat dissipation. Under the condition of no auxiliary natural heat dissipation, the TPS5430 is recommended to run for a long time within P≤10W, and the TPS5450 is recommended to run for a long time within P≤15W 3、Output Voltage: Recommended that users use within ± 5V ~ ± 15V, the conventional voltage including ± 5V, ± 9V, ± 12V and ±15V 4、Practical and Reliable: Dual output power supply module with reverse connection protection, low noise, low ripple; with input and output power supply and indicator, with positioning holes 5、Scope of Application: Positive and negative output modules are suitable for industrial automation control, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation
