Dayton 4Z829 DC speed control is designed to regulate DC motor speed in conveyors, centrifuges and packaging equipment.
Features:
- Dayton DC speed control 4Z829 features a silicon-controlled rectifier (SCR) to convert AC voltage to DC voltage, thereby providing variable speed control for DC motors.
- It is integrated with a trimpot for easy acceleration & deceleration adjustments and a patented Power Start feature that offers more than 200% starting torque, thus ensuring the startup of high frictional loads.
- This unit provides motor overload protection to prevent motor burnout & nuisance trips.
- It comes equipped with a tachometer to record unloaded speed and is packed in a rugged NEMA 4 / 12 rated enclosure for protection against dangerous electrical parts.
- The model is facilitated with run / stop & forward / reverse switches for ease in operation and comes with a Dayton DC speed control manual for user convenience.
- It features transient and surge suppression ability to protect the motor against sudden electric surges.

Frequently Asked Questions:
Q. What is the operating temperature range for this Dayton DC speed control?
A. It has an ambient operating temperature range of -10 to 45 degrees Celsius.
Q. Does the trimpot unit require calibration post-installation?
A. The adjustable trimpot unit is mostly factory calibrated. It can be readjusted for special cases by manually adjusting the minimum / maximum / acceleration / deceleration speeds or slip compensation (V/Hz) of the DC control.
Q. Why are speed controls needed in a DC motor?
A. In most mechanical applications, a speed control controls the device's speed fluctuation to maintain a constant (or diminishing) torque. It is designed to perform in only one permanent magnet or shunt wound DC motor.
