BLOCK safety transformers are the ideal choice for designers who require a compact design, maximum safety, and reliable performance.

With their compact dimensions and low weight, these transformers can be easily integrated into densely populated printed circuit boards. Thanks to SELV compliance, short-circuit resistance, and self-extinguishing potting material, the transformers meet the highest safety standards.

Key technical specifications:

• Insulation class EN B (130 °C), UL Class 105
• Ambient temperature: –20 °C to +50 °C
• Protection class II, protection rating IP 00, overvoltage category III

International approvals such as EN 61558-2-6, VDE 0570-2-x, cURus according to UL 5085-1/-2, and CSA 22.2 ensure worldwide use and compliance with standards.
