HANMATEK HM305T Laboratory Power Supply 0–30V / 0–5A, Adjustable DC, 4-Digit Voltage, Current, Power and Time Display, Variable Switching Digital Power Supply with PC Software

High Precision: The HANMATEK variable regulated DC power supply can display output current, voltage, and power on a 4-digit screen. Time can also be displayed, and the decimal point is automatically rounded. Output voltage: 0–30V, output current: 5A. Voltage resolution: 10mV; current resolution: 1mA.

Reliability and Safety: This variable regulated DC power supply features five powerful protection functions: over-voltage protection (OVP), over-current protection (OCP), overpower protection (OPP), over-temperature protection (OTP), and short-circuit protection. It includes a protective function and is equipped with a temperature-controlled cooling fan.

Multifunctional: The front dual USB charging interface (5V 1.5A) supports charging and repair. The one-touch output on/off switch allows you to preset voltage and current values when the output is off, making operation more convenient. A single button switches between voltage and current stabilization and automatically locks the keypad to prevent incorrect operation.
