RD-30

running 24/7 last month with (2) G4's & Fedco 2-342

running on a 3.2A PS at 24v

measured running current draw 0.3A (with clamp-on meter), up to 0.7A at free flowing

curious as to low current draw as measured

also note, must turn pump on/off with switch in DC line, not AC line or pump often fails to restart (as documented by Iwaki)

Iwaki calls for min. 22v to start, haven't tested that yet
