SE350 Power Dissipation 8 watts maximum
SE350 Size 3.94" L X 2.66” W X 2.20" H
EMI Suppression Internal Electromagnetic Interference Filter (EMI Filter )
SE350 Mounting can be mounted in any plane.
SE350 Fuse 4 Amp, 250 V, 5 X 20 mm fuse is supplied with the regulator (Part A-527066).
SE350 Exciter Power Circuit
Connect the regulator wire F+ to the generator F+ or Fl field terminal.
Connect the regulator wire F- to the generator F- or F2 field terminal.
SE350 Sensing / Power Input Circuit
Input power and sensing is achieved through terminals 3 and 4. The voltage input requirement of the SE350 is 190 to 240 Vac.
SE350 Voltage Adjust
The screwdriver adjustable potentiometer adjusts the generator output voltage. Adjustment
clockwise increases the generator output voltage.
SE350 Stability Adjust
Decreasing the stability makes the generator less sluggish and faster to respond to load transients. If the stability of the regulator is decreased too much, the generator will tend to hunt under steady state conditions.
