TAECL
has developed Solid State Relays specially designed for capacitor
switching. TAECL offers high voltage high current Solid State
Relays for switching capacitive loads. These SSRs have high Peak
Inverse Voltage, above 1600V and have ultra low zero-cross
switching capability. With the use of Extra large Thyristor chips with
high surge current rating these SSRs are ideal for Capacitor
switching applications. TAECL offers SSRs with surge current 5400
Amps and RMS current of 300 Amps. These high current and voltage
rating is possible because we use Silicon chips form instead of
discrete products for SSR.

Series features:
·High PIV- Specially designed for capacitor discharge
application with high PIV 1600V/1800V and ultra-low zero
crossing switching and high I2t rating.
·Back to Back SCR - The use of extra large Thyristor
chips enables high surge current rating. Surge current rating of
5400 Amps and RMS current of 300 Amps.
·DCB Technology – DCB (direct-copper bonded) Technology
virtually eliminates mismatching and repeated expansion at solid
interface. The thermal expansion co-efficient of the bonded unit
closely matches with that of semiconductor device. This method
provides lower thermal junction to case resistance
·High dv/dt rating due to the use of SCR chips.
·High isolation voltage of 4000V between heatsink and
input and output.
·Contact-less switching and built-in drive circuitry reducing
EMI generation and maintenance cost.
