Product introduction:

Conditions of Use
The altitude does not exceed 4000m;
Ambient temperature: -20 ℃-+ 40 ℃;
Relative humidity: 85%
Install in a well-ventilated room.
Allowed AC grid voltage fluctuation range is 160V-250V;
No conductor dust and no corrosive gas in the use environment;
No explosion danger, no severe vibration and shock

Precautions
The power supply should be installed in a place with good ventilation, and avoid contact with corrosive substances such as acid and alkali. When connecting with the motor side, do not reverse the armature excitation. When connecting with the electromagnetic motor, it is absolutely not allowed to open the excitation circuit or commutate by excitation, otherwise it will damage the ring motor. In addition, do not touch any component inside the machine by hand to prevent electric shock. The capacity of the fuse BX is 3-1.5 times the rated output current of the selected power armature. When installing, please ground the power supply shell reliably.

SK Series DC Control Power Supply
SPEED It is a speed regulating potentiometer, and its resistance is 4K7.
MIN.SPEED When the speed potentiometer is turned to the lowest speed, use this potentiometer to adjust the minimum output voltage
MAX.SPEED When the speed potentiometer is rotated to the highest speed, use this potentiometer to adjust the maximum output voltage
IR.COMP Used to adjust the speed change rate of the motor under no load and load.
CUR.LIM Maximum output current adjustment, this is already set to the maximum output current when leaving the factory, no special circumstances, adjustment is not allowed
LED1 power indicator After the power is supplied, this indicator shows
LED2 overheat indicator When this indicator is on, it means that the temperature of the power supply is too high, it may be that the power output power is overloaded or the heat dissipation is not good.
LED3 short-circuit indicator When this indicator is on, it means there is a short circuit in the armature circuit. Please check the motor for short circuit.
LED4 indicator This indicator is displayed when the motor is working. Adjust IR.COMP. If this indicator flashes, adjust the IR.COMP potentiometer counterclockwise.
CW / CCW: forward and reverse control ON / OFF start, stop
RES: braking resistor AC1, AC2 input 220V
A +, A-: motor armature

F +, F-: motor excitation

SK400AH, SK400BH, SK800AH, SK800BH are equipped with forward and reverse relays. The energy consumption braking relay is controlled by a built-in single chip computer. There is no spark interference during the commutation process. If you need a motor in the forward and reverse directions during work, please use the above four types of power supply. In addition, the start and stop time can be adjusted according to user needs, without special requirements, generally in 5S.
