Product Details

Switch mode power supply transformers format E25 & ETD, 15 W switch mode

From Myrra the E25 and ETD Series flyback transformers form the core of a switch mode power supply in association with a specialised circuit (VIPer, TOPSwitch, CoolSet, or control circuit + Mosfet.) Constructed with reinforced insulation, the E25 and ETD Series of flyback transformers exclusively use UL94-V0 listed materials.

Features and Benefits:
• Primary / Secondary Insulation ≥ 4000V
• Primary / Auxiliary Insulation ≥ 1500V
• Creepage distance Primary / Secondary ≥ 8mm
• Secondaries can be connected in series or in parallel.
• Materials comply with UL94-V0

Standards

IEC 950, IEC 61558 for reinforced insulation

Open Frame - Laminated

PCB mounting mains transformers with a single 230Va.c. or twin 115Va.c. 50/60Hz primary winding. Independent secondary windings may be connected in series or parallel to give a wide range of output voltage and current options.

Double section metric bobbin construction
Full varnish impregnation
