Key Features
- Upgraded DC Power Supply: The upgraded DC power supply integrates various advanced functions. For example, precise coding knobs, USB and type-c fast charge, OCP short circuit alerts, high-definition four-digit display and multiple security protection Settings
- Coarse and Fine Coding Knob: Unlike other coding knobs, this bench power supply is equipped with coarse and fine tuning coding knobs, the coarse tuning knob sets the value before the decimal point, and the fine tuning sets the number after the decimal point. The combination of the two knobs greatly improves efficiency
- USB and Type-C Charging Port: One of the major advantages of our variable power supply over other variable power supplies is the addition of the TYPE-C fast charging port, which is different from the normal USB charging port and has a 5V/3.6A output for quickly charging your cell phone or other device, or for charging a device to be repaired
- Short Circuit Alarm: Safety always comes first. When the load equipment is short-circuited, the adjustable power supply will automatically stop the output and emit a buzzer to remind the user. Not only that, the adjustable power supply also has the functions of grounding wire, leakage protection, overheating protection, voltage overload protection and power overload protection
- Wide Applications: The adjustable dc power supply features an intelligent temperature-controlled fan and heat sink for excellent heat dissipation and is especially suitable for laboratory, electronic repair DIY, communication equipment maintenance, products line, scientific research and teaching units
- Packaging: 1 x variable dc power supply, 1 x output power cord, 1 x input power cord, 1 x user manual. Tip: If you want to turn off the key beep, press and hold the voltage knob for a few seconds until you hear a beep, then the key beep will turn off
