SY 9223-439

The SY 9223-439 transformer causes a voltage transformation Uin / Uout = 1 / 2 and is designed for operation with hand- held field coil – e.g. FESP 5132 when performing tests according to IEC 61000-4-39. For this purpose, the field coil must be excited with the signal voltage of over 60 Vrms at 134 kHz to reach the field strength of 65 A/m. Other applications in the frequency range up to 1... 3 MHz are possible.

Dielectric strength:  ≥100 V
Max. current per conductor:  500 mA
Coaxial connector:  BNT-50-0-1
Symmetrical connector:  Screw terminal
Housing material:  polycarbonate
Housing dimensions:  17.5 x 58 x 90 mm
Fastening:  DIN support rail 35 mm
Weight:  53 g

  • SY9223-7637-4_Balun

 

SY 9223-7637-4

 

The SY 9223-7637-4 is a balanced-to-unbalanced transformer (abbr. balun) - transforming an unsymmetrical RF signal into a symmetrical one while not transforming the impedance. A bidirectional direction of operation is possible. The SY 9223-7637-4 has a low insertion loss, a wide range of bandwidth and can dissipate a big amount of power.

 

 

Frequency range:  9 kHz ... 50 MHz
Nominal impedanz:  50 Ω nominal
Continuouse power dissipation:  100 W
Impedance ratio:  1:1
Return loss:  typ. >15 dB @ 30 Mhz
Insertion loss:  typ. <0.3 dB @ 30 MHz
Amplitude unbalance:  <0.5 dB
Connector symmetric:  2x N-connector, 50 Ω between the two inner conductors
Connector unsymmetric:  N-connector, 50 Ω
Length:  160 mm
Width:  105 mm
Height:  50 mm
Weight:  ca. 0.5 kg
