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: A led lamp with a dedicated power to bring a few lights: Know the exact power of LED lights on the best, your power is 24 * 4.2 = 100.8W, the 100.8W in addition to the light of the power per meter can, if I do not know, look at the following: One, the same circuit with LED lights, but the power and LED quality is different Why? 1, LED lights with the first launch, because the price space is relatively large, light manufacturers are using high current consistency, high brightness LED chip, this type of chip current is: 0.02A; Later, due to the price of light bulb market competition, many lights with manufacturers to use the brightness is not high, the current is not consistent with the LED chip, this type of LED chip current is: 0.011A. 2, then we use the most commonly used 5050 lamp beads, for example, first calculate the power of a lamp beads: If it is good quality LED chip: a single chip current of 0.02A, then a lamp current of 0.02A × 3 = 0.06A. If it is poor quality LED chip: a single chip current of 0.011A, then a lamp beads current 0.011A × 3 = 0.033A. 3, now we come to calculate the power of three for a group Good quality chip: 12V × 0.06A = 0.72W, 1 meter lamp with 60 lamp beads composed of 20 groups, 1 meter power 0.72W * 20 = 14.4W Poor quality of the chip: 12V × 0.033A = 0.396W, 1 meter lamp with 60 lamp beads composed of 20 groups, 1 meter power 0.396W * 20 = 7.92W

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: PIC microcontroller used in the industrial field, the power supply using switching power supply plus B0505 isolation module, anti-jamming performance is better: Certainly better, or else else to develop this power module why? All with a direct switch power supply! The

Q: Industrial 24V switching power supply outlet "-" Is it necessary to connect with the earth?: ndustrial 24V switching power supply outlet "-" There is a need and the earth connected. The negative grounding of the power supply can greatly prevent the differential mode interference and improve the stability of the circuit.

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

Q: Industrial electricity (380V) what the color of the wire, which is the line of fire, which is the zero line: 30KW current about 60A or so, calculated by P = ui to calculate, mainly to consider the line voltage and phase voltage conversion, 380V should be replaced by phase voltage. ? 60A of the meter generally do not have to consider the installation of a more current transformer, 75 / 5A on the line, so that the secondary current in the 4 amps, the meter with 5A on the line, calculate the power when remember to multiply 15 times.

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: Industrial power cabinet generally use what brand of power: 2.PowerWARE, EATON subordinate brands, including SANTAK is EATON's brand, also accept direct engineering orders, that is to provide products while also providing engineering services and engineering warranty service.

Q: Site with industrial power 380V / 50hz, electrical equipment is 110v / 60hz. Is there a solution?: The simplest solution, no 380v, 220v direct lighting, then 220v turn 110v transformer, output 110v, 50hz, then the equipment. Not a big problem
