Technical data toroidal transformers

Construction

TRZT = open with covertape

TRHT = rest hole potting

TRWT = mounted on a metal angle

TRVTP = potted in a round housing - print version

TRVTF = potted in a round housing - free wire

TRVTE = potted in a rectangular housing - print version

TRVTU = potted in a round housing - print version

Temperature class

T40/B

on request insulation class F (155°C)

Protective class

IP00 (for mounting in an appliance)

Phases 

1 or 3

Frequency

48 Hz up to 400 Hz, at other frequencies than 50 Hz, the transformer will have another power at the same type size

VDE/SEV safety standards

open: EN 61558

potted: EN 61558

UL/CSA safety standards

on request UL/CSA materials or UL-approval

Test voltage

EN 61558-1-2/4: 5000 V pri -sec

Short circuit strength

partly short circuit proof with

- PTC

- temperature fuse

- temperature switch

- mini fuse

in other cases not short circuit proof

Core insulation and housing

Material:

Polyamid 6 class B = 130°C

with UL-approval UL 94 V2

Insulating tape

Polyester (Mylar) class B = 130°C

with UL-approval UL 94 V0

Copper wire

Polyimid mod. class H = 180°C

with UL-approval

Screen winding

Screen with copper tape, this reduces the max. power at the same type size
