2010 new HW-A-1040 improved type B is A wide voltage 450/750v voltage general type dc governor, better to improve the chips
Output the PWM more perfect

Thank you for your friends are always support, from February 18, 2010 HSBC electronic technology production HW-A-1040 B type dc governor prices
Adjustment for 108 yuan and invites dealers, hope all new and old customers eager join, we give the superior, price and quality.

HSBC electronic production HW-A-1040 type B, dc non-polar governor, device is imported Japanese electronics company production
Semiconductor IGBT transistors, through the strict select devices and assembly debugging, company has strict quality testing system, ensure
Each product qualified leave the factory.

Each only weighs 160 grams

Brand: innovation
Type: HW-A-1040 B
Technical index:
(1) working voltage: DC9V-DC35V
(2) control power: 0.01 1200 W
(3) the static current 0.02 A (standby mode)
(4) and that the voltage: 0 v, 0.2 v
(5) the 12 V power when 600 (W) 24 V when 1200 (W)
(6) rated fever current: 43 A (maximum output current)
(7) : 12000 HZ ac frequency
HW-A-1040 type B PWM dc governor, is A low loss the PWM voltage range (measured DC9V to DC35V can work normally)
Appearance is exquisite, output power and control wide range, the advantages of high sensitivity, HW-A-1040 type B governor easy installation, parallel, and series-parallel connection mode.

Use: a brush motor speed, electromagnetic motor speed, and automotive cooling fan speed regulation, car, car windshield wipers fan control motor speed,
Pipe exhaust fan speed control, running machine speed regulation, production line speed, electronic fan belt speed regulation, electric skateboards speed regulation, dc motor speed control
A brush motor speed high-power, computer fan parallel the speed.

Pulse width modulation of all points WidthModulator, called: "because of its special PWM, performance, are used
In dc load loop, lamps and lanterns light or dc motor speed control, HW-1040 type B governor, is to use the pulse width
Modulation (PWM) principle of making motor governor, governor has been in: industrial PWM dc motor speed, industrial transfer
Belt speed regulation, lamplight illume mediation, the computer power supply, dc electric fans, such as heat used widely.

HW-A-1040 type B (DC12v24v voltage universal) governor, working principle: is through the change of the output pulse of empty
Than to keep the average load current power from 0 to 100% change, and change the load, lamp brightness/motor speed.

Using pulse width modulation (PWM) mode, realize light/speed regulation, it is the advantage of power energy power, can get fully
Use of the circuit, high efficiency. For example: when output for 50% of square wave, pulse width modulation (PWM) circuit output energy
Power also to 50%, almost all of the energy conversion to load.

And the common resistance step-down speed regulation, to make the load when get power supply 50% of the largest power, the power supply must be provided
More than 71% of the power output, the 21% of consumption in the pressure drop and heat resistance on consumption. Large cloth part in the electrical energy
Resistance is consumed on the left, the energy, the output is conversion efficiency is very low.

In addition HW-A-1040 type B because of the way the speed switch heat consumption hardly exists, HW-A-1040 type B speed regulation in low speed
Torque is very large, because governor with automatic tracking PWM, in addition the pulse width modulation (PWM) mode, can make
Load at work almost full power supply voltage, get this helps to overcome motor coil and inner resistance motor
Have a more torque power.

When installation, please note:

In removing the enclosure to the following process

1, first on the Allen screw loose potentiometer.

2, make an effort to choke stay with his left hand, right hand fingers with shell buckle aperture to one side to dig a shell.

3, in the first take out circuit board to fixed board screw loose, avoid by all means do not force move potentiometer so as to avoid the potentiometer, try not to damage the operation steps.

Figure (1)

Instructions: speed switch has four terminal, specific wiring method please reference pictures (1) text stated as follows,
(1) negative: connect the dc power negative or use the battery by battery when fumbling,
(2) positive: connect the dc power is used when the battery and or pick up battery anode,
(3) motor positive: motor positive by dc power positive or use the battery by battery anode, when
(4) motor negative: motor negative by governor motor negative

Wiring is correct, electricity clockwise adjustment knob and, at this moment can be heard or feel speed switches have internal clear voice, then prove internal switch has been open
As the point of view of the knob and the constantly increasing control motor speed constant acceleration, when the knob and spin the speed of the motor is also reached the speed.
Note: do not meet the are aligned

Province through cargo can be with charge

Hoau logistics, JiaJi logistics and all kinds of freight forwarding company can be according to different places, with with different logistics company. Provincial general freight is 20 yuan up to the province, general is 15 yuan on, freight volume to calculate, general goods choice freight company is better. Note: the order quantity with freight transportation is applicable, freight also much less. With the shipping company generally don't payment of freight, shipping goods mainly to pay!!!!! Special note: all of the freight according to actual condition to billing, took a products please contact with the shopkeeper!!!!! Any inconvenience, please understand!!!! Thank you! The post office: surface mail to the charge standard of postal: charge (6 to 15 days to go to the post office, energy-saving lamps not hair surface mail himself); (EMS) express: billing standard can be online in general is 20 yuan ten-day, since, billing site: http://www.ems.com.cn/ems/postage.jsp logistics, express: ShenTong express: the head of state of 15 kg weight 1, 2 yuan for 1 kg weight; 1 kg weight area 15 head of state, May 15 yuan for weight 1 kg (different areas, freight is not the same).
