Trumpai apie prekę

Prekė: PWM maitinimo šaltinis, vožtuvų ir nustatytojų testeris. Kategorija: Diagnostiniai testeriai ir sąsajos.

• Gamintojas: no brand
• Modelis: PWM

Technical Specifications:

• - Power supply voltage max 16V
• - Output signal frequency 150Hz, 10Hz (selectable by switch)
• - PWM duty cycle adjustable range: 1% ÷ 99% (smooth adjustment with potentiometer)
• - Maximum output current 20A (50A pulse, at 10Hz frequency)
• - Protection against reverse connection of cables to the battery

The device allows for:

at 150Hz frequency

• ----------------------------- smooth speed control of DC motors
• ----------------------------- control of electromagnetic actuators, pressure regulators, EGR valves, etc.
• ----------------------------- control of the regulating valve in air conditioning compressors

at 10Hz frequency

• ----------------------------- opening injectors in gasoline and diesel systems during cleaning in an ultrasonic cleaner
• ----------------------------- pulsed testing of certain types of actuators

The power supply can be used to start the idle settings visible in the photo next to it. These settings are incorrectly called stepper motors. They are available in FORD and VW cars. These are elements operating on the principle of solenoid valve which are powered by PWM signal. In some settings, to move the choke you need to give vacuum to the air chamber. In other words, they only move in the car with the engine running. In this case, you can check the setter using the frequency of 10Hz. Instead of smooth movement, you will then be able to hear a clear tap at the moment of impulse. The 10Hz signal can also be used to open the injector spire during cleaning in an ultrasonic cleaner. The maximum output current of 50A in the pulse allows you to connect several injectors at the same time in the washer. In this case, the device must be powered by a battery. A typical stabilized power supply will not give such a large current in the pulse.
