The specs indicate 60 V coll to emmit and 70 V coll to base and collector current of 10 amps.
Question :: is the voltage too low to push 10 amps on a device rated for 60 to 70 vlots??
Is there an easier way to build a % time on controller?

A bipolar transistor does not have a GATE.Oxford wrote:If I hold the gate high directly from the battery , the amps are the same as when pulsed with a 555 timer. The real amp load is 2.12 A when hooked in series with amp meter to the battery.
