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
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.
