Application Scope
Driving and speed regulation of DC motor, high precision DC power supply.

Function Structure
OL series of DC drive is mainly used to drive DC motor, and widely applied to welding tube mill industry. Its unique weak magnetic control circuit can ensure a wide speed regulating scope of DC motor. Its steady digital DC control circuit can not only make the DC drive has a stable work and strong anti-interference ability, but also has a good user interface which is convenient for operation.DC drive includes: 3-phase 6 pulse SCR rectifier, SCR excitation control module, full digital DC control circuit.

Technical Features
Ø Perfect structure design

1.Integration design of DC drive with the features of compact structure and small size. Original type or extension type structure is optional.

2.Main loop thyristor adopts high efficiency air cooling radiator which is convenient for installation and maintenance.

3.High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.

4.Closed cabinet design, meeting rigor environmental requirements on site.

Ø Full digital control system

1.Adopt 590DIGITAL series full digital controller to realize precise synchronous trigger with high control precision of motor speed and rapid response speed.

2.Motor operation parameter adopts digital menu setting, which is convenient and flexible with good HMI.

3.The power supply has perfect protection function with reliable working and low failure rate.

equipment selection*

1.Select DC drive model as per rated voltage and rated power of DC motor.

2. The DC drive needs to reserve 20% power margin.

Q:Industrial 380 inverter how to enter the home 220 power supply work: Surely need to install the press

Q:What is the frequency of electricity in Bangladesh?: The Bengal is one of the ancient peoples of the South Asian subcontinent. The earliest inhabitants of the Bengal region are the Australians. In 1757, Bangladesh became a province of British India, India in 1947 after the partition, belonging to Pakistan, known as the East Pakistan. 1971, separated from Pakistan and independent.

Q:Do you need a separate dedicated power supply for each color dome camera?: General color hemisphere no infrared lamp power consumption is small, a 1A power supply if it is safe, then with 2 is no problem

Q:What is the industrial electricity voltage and frequency of Peru, Ecuador and Colombia?: Ecuador's industrial voltage and frequency are: [single phase] 120V / 127V, [three phase] 208V / 220V, [frequency] 60HZ;

Q:S-350-12 monitoring dedicated switching power supply 12V29A transformer connection: may 1, you are on the wiring when the burning, it is the power is not big enough, is overloaded work. 2, you do not connect, may be connected together positive and negative, resulting in short circuit burned. Recommendation: change the new power supply, it is necessary to connect all the lines, and then the first group, to see the heat situation, to determine whether the next group.

Q:UPS uninterruptible power supplies, electronic power products, industrial computers and embedded computers.: If you really want to reduce the competition, then I think you only have to negotiate with the rotten, the oil, Sinopec bought, and then you start selling oil, so in China you really can not find a competitor.

Q:PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better: You use the PIC with which models, switching power supply to the chip power supply is no problem, the key is to single-chip power supply filter to do a good job. Relay output to use optocoupler isolation and so on. B0505 output test must have a small load and input and output must be added filter capacitor, otherwise interference is great.

Q:Fire emergency lights and evacuation signs need to receive a dedicated fire power on it?: If connected to the fire power, because the fire power is uninterruptible power supply, it will appear in the power failure can not be lit and lose the proper role. Indicator signs for the bright signs, generally also with a battery inside, also need not be connected to the fire power.

Q:Industrial UPS power supply how to choose?: UPS power supply battery size determines the length of the load power supply, the specific load is also based on the need to set, such as: If the injection machine in the electricity after the break need 1 hour power supply to ensure its normal stop, then our battery Size needs to be based on the size of the injection molding machine to match the appropriate battery, any of the Group's UPS power supply can match the UPS battery, you can also have their own customers to buy.

Q:What is the difference between computer power and industrial switching power supply?: Industrial work conditions are poor, the temperature is high. Computer power is slightly lower. The other is almost the same
