SAIKE 305D DC power supply belongs to the single output precision DC power unit. Its output voltage and output current can be continuously adjusted within the rated range. Because of 305D the load current with MA conversion, the output current is divided into two grades such as 0-5A and 0-999mA. This power unit can automatically change the work mode.
With the dual digital display screen, both output voltage and output current can be independently displayed. 305D DC power supply come with many functions, such as current limiting, voltage declining, short circuit protection, over-temperature protection, and more. As the essential instrument of communications industry, it is widely applied for production lines, maintenance, and debugging in telecom products factories. This device is also commonly found in laboratories and other places.

Constant Voltage Constant Current (CV / CC) Principles
305D DC power supply can be automatically converted in the case of constant voltage constant current working mode. Through the comparison between the values of load current and limited current, you can determine its status.
1. Constant Voltage Mode (CV)
When the current value is smaller than the set output limited current value, the power supply unit will work in constant voltage mode. Under such condition, the constant voltage indicator of front panel will light up, and the output voltage will be controlled to be the same as the set value. The current will change according to the load.
2. Constant Current Mode (CC)
If the current value is greater than the limit value of the output current, the device will work in the mode of constant current. Additionally, the constant current indicator of front panel will light up, while the output current value will be controlled no more than the set value.
Because the limited output power can not overload, the output voltage will be lower than the set point. Once the output current is lower than the set value, the SAIKE 305D DC power supply will automatically be converted to the work status of constant current.
