BLOCK - Transformer, 230V, 0.35VA - 24V
BLOCK safety isolating transformer, 230V primary, 24V output, 0.35VA. Encapsulated, short-circuit proof, for PCB mounting.
The BLOCK safety isolating transformer is designed to provide reliable voltage adjustment and simple electrical isolation for a wide range of applications. It is suitable for creating SELV and PELV circuits, thanks to the limited output voltage, ensuring maximum safety for connected devices. Featuring XtraDenseFill resin encapsulation, this transformer offers permanent corrosion protection, high insulation values, and exceptional electrical reliability, even in demanding environments.
This compact, encapsulated transformer is inherently short-circuit proof and designed for high ambient temperatures, making it a robust choice for continuous operation. With a 230VAC primary voltage and a 24VAC secondary output, it delivers a rated power of 0.35VA and operates at a frequency range of 50 to 60Hz. The transformer is available in a minimum size with high output, and it can also be configured with dual output voltage for series or parallel connection, offering flexibility in various circuit designs.
The BLOCK transformer is constructed with pins for printed circuit board (PCB) terminals, featuring a 0.6mm pin diameter and compact dimensions of 22.7 x 15 x 22mm (W x H x D). It has an ambient temperature range of -20 to 70°C, making it suitable for a variety of industrial and electronic applications. The self-extinguishing potting material enhances safety, while the IP 00 protection index and VDE=B, UL=class 105 insulation class ensure compliance with international standards.
Compliant with VDE 0570 Part 2-6, DIN EN 61558-2-6, EN 61558-2-6, IEC 61558-2-6, UL 5085-1/-2, and CSA 22.2 No.66, this transformer is ideal for applications requiring safe electrical isolation and voltage transformation.
