The Semikron SKRC 440-2 is an RC snubber network designed for applications up to 500A rms load current. Its primary function is to limit the rate of rise of voltage spikes, protecting SCRs from exceeding their dV/dt ratings. This module also aids in improving SCR latching current for low-level inductive loads.
Key electrical specifications include a capacitance of 47nF, a voltage rating of 440V AC, and dual resistance values of 68Ω and 9Ω, with a capacitance tolerance of ±10%. The operating temperature range is from -40°C to +50°C.
Mechanically, the unit measures 92 x 21 x 28mm. It features a tab mounting type and has 2 elements. The snubber network is encapsulated for compatibility with isolated base diode and thyristor modules, with connections made via convenient push-on receptacles.
Warning: These devices are designed for direct connection across a mains supply but should NOT be used in positions where capacitor failure could expose anyone to electric shock.
