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 rectangular housing - flat plugs


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, other frequencies than 50 Hz lead to another power at the same type size


Safety standards VDE/SEV
open and potted: EN 61558


Safety standards UL/CSA
on request UL/CSA materials or UL-approval


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


Resistance to short-circuiting
conditionally short circuit protected with
- PTC
- temperature fuse
- temperature switch
- mini fuse
in other case no resistance to short-circuiting


Core insulation and housing
Material: Polyamid 6 gf class B = 130°C with UL approval UL 94 V2


Insulants
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


Transformer core lamination
conform to DIN 41302
M0H, 0,3 mm thick (1,0 W/kg losses at 1,7 T) or
M111-35N, 0,35 mm thick (1,1 W/kg losses at 1,5 T)


Terminals
Pins (TRVTP/TRVTU)
Solder tags
Free wires
Flexible wires
Terminal connectors (TRWT)
Plug pins 2,8 - 4,8 - 6,3 mm
Cable lugs


Mounting
with central mounting, two rubber washers, a metal disk or with a screw in the potted centre


Voltage
depends on the size, max. depends on the type size, vacuum potting: 5000 V


Tappings
possible


Current
max. 2000 A
