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 to ensure the stability and reliability of product operation.
Featured functions
CV / OC with 2 times overload ability (except for models with 500A)
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.
1. 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.

2. 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 è continuous working with load

100% ~ 125% rated current value è withstand 600s continuous working

125% ~ 150% rated current value è withstand 60s continuous working

150% ~ 200% rated current value è 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
The power supply has an automatic line voltage drop compensation detection terminal (comsense). Connect the terminals to the load ends. The power supply will automatically detect the voltage value of the load ends and automatically compensate for the line voltage drop caused by the power line. At the same time, it can be customized to detect whether the battery terminals are connected reversely to realize the anti-reverse protection function for battery charging.
Fast self-discharge function
The power supply has built-in discharging circuit, which can quickly release the electrical energy in the output capacitor after the power supply stops outputting, 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-circuited 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.
