LeTkingok 110V Adjustable DC Power Supply QW-MS3010D 30V 5A 150W Features: 1. Thicker steel chassis, nice, durable. Handle design, easy handling. 2. Voltage and current are used coarse and fine design, precise adjustment of the output voltage. 3. Constant pressure, constant current automatic conversion, when the constant voltage source can also be used as a constant current source. 4. Protection function perfect: OVP, OCP, OTP. 5. Line design is reasonable, the key components imported, can be used 24 hours full load. 6. PWM switch pre-regulator, MOS linear adjustment mode, high efficiency, energy saving, close to linear power performance, efficiency is much higher than the linear power supply, linear power supply replacement products. 7. Intelligent temperature control fan, adjust the speed according to the load, effectively reduce noise and extend the life of the fan.
