DC Power Supply Variable 30V 10A 300W Adjustable Switching Regulated DC Bench Lab Power Supply with Encoder Knob Adjustment 4-Digits LED Display for Laboratory School DIY Electronic Research ( Item#: E25729EU )

DH series is a single output CNC DC switch power supply. It is characterized by high output power and compact size. In addition, the DH series can be equipped with an RS232 communication interface and supports SCPI communication protocol and Modbus communication protocol. Enabling the DH series to connect with other devices and support user to conduct secondary development.
Regardless of your design and testing needs, the DH series are able to provide versatile solutions.

Features:
LED Digital Tube HD Display: Using LED digital tube high-definition display, providing users with rich functions, simple operation of the human-machine interface.
2 Groups of Data Storage Function: With two groups of data storage function, "M1-M2" a key storage call, easy to operate.
Various Protection Functions: DH series provides over-temperature (OTP) over-voltage (OVP) over-current (OCP) reverse polarity protection, can be set through the panel or the host computer operation of the power supply output over-temperature/over-voltage/over-current protection point.
Compact Size: Small size does not take up space, go out more easily to carry, to solve the problem of traveling to occupy space.
Low Noise and Ripple: Low ripple and low noise, stable data, ensure work efficiency, is a reliable power supply equipment model for engineers.
Wide Range of Applications: Used in the field of testing, aging, LED drive, industrial control, solar regulation, battery charging, etc.
