4. مصنوعات کی خصوصیات

• Automatic Power Calculation: Unlike other DC power supplies, the WANPTEK DPS305U automatically calculates the power value. It simultaneously displays voltage, current, and power values with a precision of 0.01V, 0.001A, and 0.001W.
• 5V / 3.6A USB Interface: Equipped with a high-speed charging protocol identification chip, this variable power supply supports USB fast charging. It provides a 5V / 3.6A output, allowing for quick charging of mobile phones and other devices, or for powering devices under repair.
• Short Circuit Alarm: Designed to enhance safety and extend the lifespan of the DC power supply. When a short circuit occurs, the adjustable DC power supply unit stops output and emits an alarm. The bench power supply includes safety protections such as over-voltage, over-current, over-temperature, and overload protection.
• وسیع درخواست: This adjustable power supply features an electrically controlled fan and an excellent heat sink for efficient heat dissipation. It is particularly suitable for laboratories, electronic repair DIY, communication equipment maintenance, product lines, scientific research, and educational units.
• اعلی صحت سے متعلق: The power supply boasts a high resolution of 0.01V and 0.001A, ensuring accurate and stable output.
