Do you have a bunch of solenoids that need 12 V power, and need to be switched faster than a normal relay? You could handle this with a bank of solid state relays, but this can get expensive and bulky. Our new HSD-4 module packs four 8 amp high side drivers into a compact package. Applications include using MicroSquirt to control a Supra A340 transmission, or using the MS3-Pro to run a BMW Double VANOS system. Priced at $79 plus shipping.
