Functions
Working modes
The power supply has two working modes: CV / CC mode and CV / OC mode, customers can select different working modes according to actual use requirements. CV / CC mode Under CV / CC mode, the output voltage and current of power supply are continuously adjustable from 0 to the rated value. Power supply works either in constant voltage (CV) or constant current (CC) state, the CV & CC working state are automatically switchable, the switching conditions are determined by the voltage & current set values and the customer's load resistance value. For details, please refer to the following figure. In CV state, the output voltage is adjustable and regulated, the output current varies with the output voltage value and the customer load resistance. In CC state, the output current is adjustable and regulated, the output voltage varies with the output current value and the customer load resistance. CV / OC mode Under CV / OC (over current) mode, besides CV function, power supply still has over-current working ability, (OCP is invalid in this mode), detailed parameters as below: 0% ~ 100% rated current value: continuous working with load 100% ~ 125% rated current value: withstand 600s continuous working 125% ~ 150% rated current value: withstand 60s continuous working 150% ~ 200% rated current value: withstand 5s continuous working Power supply automatic protected and stops output when Max. Over-current time exceeded.
OVP & OCP value setting function
OVP and OCP value could be set via front control interface, power supply could automatically stop output when output voltage or output current exceeds the set protection values. OVP: over voltage protection value. OCP: over current protection value.
Automatic line voltage drop compensation function
Power supply has automatic line voltage drop compensation terminals, connect the terminals to load ends; power supply could automatically detect load end voltage value and make voltage compensation for line voltage drop. Meanwhile, this function could detect if load connection is reverse connected or not.
Self-discharging function
The power supply has built-in discharging circuit, which would be automatically activated to quickly release the energy stored in the output capacitor after the power supply stops output, so as to prevent personal injury caused by accidently touching the output terminal right after the power supply stops.
Short-circuit protection
The power supply can adapt to two kinds of short-circuit conditions as below: If the power supply has short-circuit before starting output, then power supply can be normally started and running continuously for a long time. If power supply has a sudden short-circuit during running with load, then power supply would automatically stop output and gives sound alarm, LEDs on front panel would display corresponding alarm code.
Communication port
Power supply equipped with RS485 communication port for remote control and monitoring via PC.
Analog signal port (optional)
The power supply can be equipped with an external analog signal port via 0 ~ 10V or 4 ~ 20mA signal to realize power supply start / stop control, power supply running / fault status monitoring.
24V interlock circuit (optional)
The power supply can be equipped with 24VDC output interface to build an interlock circuit with external devices.
Reverse energy discharging (optional)
The power supply has automatic reverse energy discharging function, which automatically detects the reverse energy. When the load reverses the energy to the power supply device, the built-in discharging unit would be automatically turned on, and the discharging unit would be automatically turned off after the discharging is completed. The discharging reaction time is less than 1ms.
Key technology introduction
Air duct design
Full-sealing independent "Chimney" type air duct design adopted, the inner circuit uses independent cooling fan to improve the product heat dissipation effect, and the air inlet has dustproof measures, which greatly reduces dust and debris entering the power supply. The radiator and fan can be cleaned and maintained separately The heat dissipation system undergoes rigorous simulation and actual testing, and is designed with reliability in consideration of national standards and enterprise standards to ensure that the device with low temperature rise and long life.
Modular design
The power supply follows the modular design concept and requirements. According to the analysis of product characteristics and functions, each subsystem will use components with independent functions. By the Laminated busbar structure and the use of standardized long-term verified power units, the loop sense is effectively reduced, and the reliability of the product operation is greatly improved.
Core component
The key and important core devices are all internationally renowned brands, and high-quality devices ensure the stability and reliability of product operation.
Installation environment
Ambient temperature: Please have the power source working in safe temperature range (0ºC ~ 45ºC) or it would affect life of power source.
