1-phase compensating choke INK 0.9-230V INK 1-0,9-230

Compensating chokes – optimizing the operation of electrical installations

INK compensating chokes are elements used to limit inrush currents when switching on inductive devices such as motors, transformers, or fluorescent lamps. Using a choke reduces voltage drops in the network and improves the stability of the electrical installation. Model INK 1-0.9-230V is designed to operate in single-phase networks with a voltage of 230V and a power of 0.9 kVar.

Characteristics and application

The INK 1-0.9-230V choke is characterized by high quality workmanship, which ensures reliability and long life. The choke core is made of high-quality materials, and the winding is made of copper, which guarantees effective compensation of inrush currents. Vacuum impregnation in class H varnish provides resistance to environmental conditions and protects against mechanical damage.

These types of chokes are widely used in:

• Lighting (fluorescent lamps, induction lamps)
• Electric motors
• Transformers
• HVAC equipment (air conditioning, ventilation)
• Domestic and industrial installations requiring limitation of inrush currents.

Construction and technical parameters

The INK 1-0.9-230V choke has been designed with easy installation and safe operation in mind. It is equipped with a bimetallic thermal switch, which protects the circuit from overload. The choke operates in continuous mode (100% duty cycle) and is naturally cooled (AN). Insulation class F (155°C) ensures safe operation in a wide range of ambient temperatures (up to 40°C).

The choke is characterized by an inductance of 3.91 mH, a current of 3.91 A and a power of 0.9 kVar. Its rated voltage is 230 V at a rated frequency of 50 Hz. Dimensions are L=120 mm, H=118 mm, B=120 mm, d=56 mm, e=62 mm and f=104 mm with a weight of 6.9 kg. The degree of protection is IP00.

The choke design allows for mounting using angle brackets. It meets the standards EN/IEC 61558-2-20 and EN/IEC 60076-6 and has passed high voltage tests (3 kV for 1 minute).
