91957-P2S2 Description

Short technical summary and product information.

The TALEMA 91957-P2S2 is an open style toroidal transformer designed for power applications. It offers a 120VA power rating and features dual 115V primary windings that can be connected in series for 230V input or in parallel for 115V input.

 

This transformer is equipped with twin secondary windings that can be connected in series or parallel, or used independently. Available secondary voltages include 2x12V, 2x15V, 2x18V, 2x25V, and 2x55V, each with corresponding full load current ratings. The windings utilize Class H insulation (180°C), with Class B insulation (130°C) between input and output, and Class A (105°C) for connection lead insulation.

 

Physical dimensions include a diameter of 93mm and a height of 46mm, with an approximate weight of 1.20 kg. The transformer comes with a mounting kit. It is approved to UL506 & UL5085 standards and conforms to EN61558, EN60065, VDE0550, and BS415.

 

Key electrical characteristics include iron losses of approximately 0.73W and copper losses of approximately 15.2W. The DC resistance of each primary winding is approximately 8 Ohms at 25°C.
