Toroidal transformers standard range

Product catalog summary

Overview: The document provides technical specifications for single-phase toroidal transformers, specifically the Type RT series, with power ranges from 20 to 300VA. These transformers are designed and tested according to EN61558 standards and are suitable for installation in electronic equipment.

Specifications:

Input Voltage: 230V
Frequency: 50-60Hz
Output Voltage: Maximum 2x45V
Test/Insulating Voltage: 4kV AC RMS
Construction Class: II
Insulation Class: B (130°C)
Ambient Temperature: 40°C
Degree of Protection: IP00

Design Features: These transformers are designed as safety isolating transformers with separate insulated windings, prepared for class II equipment. They are protected against short circuits and overloads with a thermal fuse on the primary side. They offer up to 50% less weight compared to conventional transformers, with low magnetization currents and no-load losses.

Applications: Suitable for use as safety isolating transformers in constructions where low weight, flexible dimensions, and optimal conditions between dimensions are preferable.

Technical Data: The document includes detailed tables listing various models of the RT series transformers, specifying their power (VA), copper loss (W), iron loss (W), external diameter (mm), internal diameter (mm), height (mm), and weight (Kg). It also provides information on secondary voltages and currents for different models.

Additional Features: Toroidal transformers with two secondary voltages can be used as separate series or parallel connected. Standard types can be supplied with a potted center hole (RTD) or potted in polyamide housings (RTV).
