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: 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: Power for ups power supply which well-known imported brands: PROTEK US original imported power dedicated models, good quality, the price is not cheap.

Q: EPS emergency power supply and DC screen is one thing, what is the difference between the two?: Mainly used in road traffic lighting, venue lighting, building fire escape lighting, fire pumps, spray pumps and other fire equipment to provide emergency power supply, EPS fire emergency power supply through the CCC China national compulsory product certification, the current state through the 3C certified EPS Fire emergency power supply size is 0.5KVA to 110KVA. EPS fire emergency power supply can be divided into emergency lighting, hybrid and power inverter EPS emergency power supply three categories.

Q: What is the allowable fluctuation range of the industrial standard power supply 380v power supply voltage?: With other levels of power supply voltage fluctuations are as follows: 35kV and above supply voltage positive and negative deviation of the absolute value does not exceed the nominal system voltage l0%. Note: If the upper and lower deviation of the electrical voltage (both positive or negative), according to the larger deviation of the absolute value as a basis for measurement.

Q: My magnetron is used in the industry, my dedicated power to start less than 2 minutes to stop,: This reason is much better, next to the investigation 1 heat problem magnetron with or without cooling fan, generally if there is no cooling or cooling broken, then the magnetron will work for 2 minutes to burn, you measure the same as the filament is passed. Burn is a magnet cracking

Q: Meizu special mobile power is which brand?: Meizu custom iWalk, but the evaluation is not high. Meizu phone on the current with the voltage is a more accurate requirements Oh, please Meizu mobile phone battery according to the technical parameters of regular manufacturers and users to evaluate the high product, the proposed choice of current 1.2A, voltage 5V. Part of the mobile power will be virtual standard, while the wire, mobile power supply itself will be some resistance to wear, before the purchase with the original data cable test.

Q: Emergency lighting should not take fire special power supply, right?: 3 .... in talking about emergency tools. All the emergency Deng has a fast battery and a module like the power of the things. (This thing with the fire touch a quick working principle, the module which has a normally open and normally closed point, when the electricity from the time he was Long open, the charging state, the mains of a short-circuit contacts normally closed, the battery will be through the module command to start the emergency lights. ???The building is the building of the 7th floor, 8th floor fire, the fire host to receive the fire signal, the host to the layer of fire strong cut a command: strong cut non-fire (this refers to the city's electricity is the lighting point ). When this layer is in a power failure state: The emergency principle according to Article 3. Emergency lights are not used fire power

Q: Multimeter measuring industrial furnace box and power supply resistance is 6-15mΩ, which is leakage it?: All metal shell equipment require reliable grounding, whether or not you can continue to use,

Q: US Industrial Electricity Voltage: 2. Requirements for "Scope A": 115 ~ 120V System: When lighting: 110 ~ 125V of electrical equipment; power supply point 114 ~ 126V. No lighting: electrical equipment at 108 ~ 125V; power supply point 114 ~ 126V. 460 ~ 480V system: (including 480 / 277V three-phase four-wire system) When lighting: power equipment at 440 ~ 500V; power supply points 456 ~ 504V. No lighting: electricity equipment at 432 ~ 500V; power supply points 456 ~ 504V. 13200V system: power supply point 12870 ~ 13860V.

Q: Computer power can be inserted in the air conditioning dedicated socket: It should be noted that the air conditioning sockets are 16A / 250V specifications, jack distance greater than the ordinary 10A / 250V socket, so the computer power plug must be replaced by 16A socket can be inserted into the air conditioning socket. Therefore, the computer power plug in the use of air conditioning socket is possible.
