Product Description:

The 175H8250 Frequency Converter was designed to manage the rotational speed of electric motors. It is commonly used in pumping systems, fans, and conveyors. It is a reliable alternative for controlling motors in industrial automation, ensuring consistent performance across a wide range of applications.

The 175H8250 frequency converter includes several efficient characteristics for precise motor control. For up to 60 seconds, the converter can deliver an intermittent 2.7 kVA output or a continuous 2.1 kVA output. The converter can withstand 5.4 amps of output current when used constantly and 6.7 amps when used intermittently. The converter is compatible with motors with capacities of up to 1.5 HP. The converter's continuous output for quadratic loads is 1.9 kVA, and it can handle motors up to 1.5 horsepower. The motor voltages of 50/60/87/100 Hz are suitable, and the maximum wire size is 12 AWG. Because of its adjustable frequency range, which is typically between 0 and 120 Hz, it can be utilized for a variety of purposes. The frequency converter includes a thermistor and thermal motor protection system that meets DIN44081 specifications.

The 175H8250 converter allows you to adjust the output frequency anywhere between zero and 500 hertz. It also includes ramp times that can be set between 0.1 and 3600 seconds, allowing the motor to accelerate and decelerate gradually. The converter supports a wide range of motor settings and safety functions, and it can control speed using both local and remote references. Overheating will not harm the motor due to the thermal protection system. The converter's adaptable design allows it to give an output voltage ranging from 0 to 100% of the AC line voltage. The converter is an ideal choice for adjusting the speed of electric motors.
