Control transformer 1.0 kVA STN1,0(400/230) 204992

Control Transformers – Reliable Power Supply for Your Installation

This 1 kVA control transformer is a key element in power systems, providing safe and stable voltage for control devices and auxiliary circuits. Designed to operate with a primary voltage of 400V, it reduces it to a safe secondary voltage of 230V, making it an ideal solution for both professional installers and end-users.

Construction and Application

The STN1.0(400/230) transformer has been designed with reliability and durability in mind. Its solid construction and the use of high-quality materials, such as copper windings, guarantee long-lasting and trouble-free operation. The device finds wide application in:

• industrial automation systems,
• lighting installations,
• electric motor control circuits,
• HVAC equipment (heating, ventilation and air conditioning),
• laboratories and workshops.

Its compact dimensions (151 mm width, 145 mm height and 150 mm depth) facilitate installation even in limited spaces. The IP00 protection class means that the transformer is intended for use in dry and clean rooms. Insulation material class B provides resistance to high temperatures.

Key Features and Benefits

• Rated power 1000 VA: Provides sufficient power for most control applications.
• Voltages: Adapted to cooperate with 400V networks (primary) and generates a safe voltage of 230V (secondary).
• Relative short-circuit voltage 2.2%: Indicates stable operation under load and resistance to interference. A lower value indicates better voltage regulation.
• Made of copper: Guarantees high electrical conductivity and minimizes energy losses.
• Compact dimensions: Allow easy installation in tight spaces.
• Insulation class B: Provides high thermal resistance of the transformer windings.
• Standby power consumption 24W: Low power consumption in standby mode translates to energy savings.

This transformer is not just a power supply element – it is an investment in the safety and reliability of your electrical installation. Thanks to precise workmanship and the use of high-quality components, you can be sure of its long-lasting and efficient operation.
