ZK-MG 30V 5A DC Motor Driver

ZK-MG 30V 5A 150W DC Motor Driver

%0-100 Speed Adjustment with Display - Panel Type Case – Duty and Frequency Adjustment

     ZK-MG is a panel type PWM DC motor driver in a case that works between DC 5V - 30V and drives loads with 5A continuous current and up to 150W power. It adjusts the output power with PWM and therefore controls the rotation speed of the motor. The 3-digit red display on the front shows the output percentage: if 55 is shown on the display, %55 of the input power is transferred to the output. Adjustment is made with a pushable digital encoder adjustment pot; a short press on the pot turns the output on and off (ON/OFF).

     The PWM frequency is adjusted between 1KHz and 99KHz in 1KHz steps and the duty cycle between %0 - %100 in %1 steps. Thanks to the soft start feature, when the output is turned off and on again the voltage is applied to the load by raising it slowly instead of all at once; the motor and the mechanics are not stressed suddenly. In the settings menu the lowest (L) and highest (H) duty limits and the operating frequency (F) are set; the settings are kept in memory and are not lost when power is cut. The input has reverse connection protection.

     Thanks to its gray 79mm x 43mm x 26mm panel type case, it is used mounted on a device front panel or a box cover; connections are made with terminal sockets. It is suitable for speed control of DC brushed motors, fan and pump speed adjustment and led strip brightness control.

Key features:

     Speed setting with percentage display: The 3-digit display shows the output as a percentage between %0 - %100; the value changes in %1 steps as the encoder is turned, so the set speed is read exactly.

     Adjustable PWM frequency: The operating frequency is selected between 1KHz - 99KHz in 1KHz steps; the quietest and most efficient frequency can be set according to the motor and load type.

     Soft start: When the output is turned on the voltage rises slowly; the motor does not draw a sudden current, and mechanical parts such as gears and belts are protected.

     Lower and upper limit: With the L and H settings, the lowest and highest duty limits are set; the motor does not leave the desired speed range. The settings are kept in memory.

     Panel type case: Its case lets it be mounted on a front panel; the encoder with ON/OFF button and the power indicator LED are on the front.

Usage information:

• When the encoder pot is turned clockwise the output percentage increases, when turned the other way it decreases. According to the setting, the input voltage is transferred to the output at a certain ratio. A short press on the pot turns the output on or off.
• A long press on the pot enters the settings menu. There are 3 settings: L: lowest limit for duty, set as 2 digits; used so that the output does not drop below a certain level. H: highest limit for duty, set as 2 digits or 100; used so that the output does not rise above a certain level. F: operating frequency, set as 2 digits between 1KHz and 99KHz.
• While in the settings menu, another long press exits the menu; the settings are saved to memory.
• Connect the power supply to the input terminal and the motor to the output terminal. The power supply must be able to provide the current drawn by the motor.

Areas of use:

•  Fan and cooling fan speed adjustment
•  Pump (water pump, dosing pump) speed control
•  Conveyor and belt system speed adjustment
•  Led strip and led lighting brightness (dimmer) control
•  Mini drill, grinding and engraving motor speed adjustment (below 5A)
•  Aquarium pump and air motor speed adjustment
•  Ventilation and exhaust fan control
•  Speed adjustment in mechanisms driven by geared DC motors
•  DC motor speed trials in robot and vehicle projects

Precautions:

•  The input voltage must be in the DC 5V - 30V range. The board is not connected directly to the AC mains (220V).
•  Continuous current must not exceed 5A; 15A is only a short-term peak current. Leave a current margin for motors that draw high current at start.
•  The board is for DC brushed motors and DC loads such as LEDs; it does not drive brushless (BLDC) or AC motors and does not change the motor direction.
•  The output transistor heats up more as the frequency rises; do not select a higher frequency than needed for a motor.
•  With inductive loads such as motors, make connections with the power off; do not short the output terminals.
