Control Techniques SKC3400400

The SKC3400400 belongs to one of the remarkable Commander SK series by Control Techniques builders. It is a variable AC speed drive that is mainly designed for the driving of three-phase induction motors. It contributes a great part to many industrial, electrical, and electronic systems due to its unique features and reliability.

Technical Specifications:

The drive SKC3400400 is designed for efficient performance, offering a nominal motor power of 4.0 kW (5.0 HP). It has an input fuse rating of 16 A, with a typical full load input current of 11.9 A and a maximum continuous input current consumption of 13.4 A. It operates on a three-phase, 380 to 480Vac with ±10% tolerance and a changeable frequency from 48 to 62 Hz.

For the purpose of heavy-duty applications, it is capable of supplying a 100% RMS output current of 9.0 A, with a 150 % overload current capacity for 60 seconds at 13.5 A. These vital overload parameters ensure that the drive can handle such demanding motor drives with proper safety and preciseness.

This drive requires a minimum braking resistor value of 55 ohms to ensure effective braking and energy dissipation. These features are one of the most technical requirements for every device that makes its working reliable under varying load conditions. Furthermore, the drive comes from type C of the SK series therefore, it has a dimension of 10.4 mm, calculated as 0.41 inches.

Operational and Installation Parameters:

Installation of drive SKC3400400 needs an environment classified as pollution degree 2 according to IEC 60664-1 standards, which means that it can only bear dry, non-conductive impurities. In addition, it is also required to place the drive inside a distinct electrical enclosure.

It is another paramount feature for installation of the drive that usage of Class 1 60/75°C (140/167°F) copper wire is recommended. For proper drive operation, the ambient temperature must not cross the limits above and below 40°C (104°F). Otherwise, it may cause problems in its desired working.

Safety Precautions:

It is necessary factor to keep in mind that the start and stop controls, or in other words, inputs of the drive, should not be used to ensure the protection of the person. They have no part in disconnecting hazardous voltages. So, disconnect the power supply through a certified electrical isolation device before getting in contact with electrical connections.

Continuous running of a motor at a slow speed can cause it to overheat as the cooling fan doesn't work sufficiently well. In order to prevent this, use a protection thermistor with the motor. If essential, use an electric fan for enough ventilation. Follow seriously, the safety instructions provided by the manufacturers to avoid harm or destruction of devices.
