|STGIPS30C60 30A IGBT bridge & 15mΩ shunt for the 1.5kW Induction Motor Speed Controller|
These parts can be used to build, upgrade or repair the 1.5kW Induction Motor Speed Controller.
The main part is the STGIPS30C60 hybrid three-phase IGBT bridge module. The originally specified part is the STGIPS20K60 and this is rated for 18A continuous current and 40A peak.
By comparison, the pin-compatible STGIPS30C60 is rated at 30A continuous, 60A peak. So this should make the speed controller more rugged and better able to withstand overload before the protection circuitry kicks in.
We're also supplying the 15mΩ 6332 (2512) SMD shunt, rated at 3W.
Note that if you want to use these parts to repair a damaged controller, chances are that IC2 (LM319; Jaycar ZL3319, Altronics Z2520) will almost certainly need replacing.
It's also possible that some or all of the high-speed opto-couplers (OPTO1, 4N35 & OPTO2-3, HCPL2531) could be damaged so check them too.
