Type PSU AC Motor Start Capacitors
Non-polarized, Aluminum Electrolytic AC Motor Start Capacitors
The Type PSU is a compact non-polar, dual voltage
rated, AC motor start capacitor constructed in a
round rugged bakelite case. To extend the life of
relay contact switches, the PSU can be purchased
with optional bleeder resistors assembled with 1/4”
quick-connect terminals. An optional mounting sys-
tem consisting of a bracket that is attached to the
capacitor case with one end cap is available. The PL
end caps are for use with wiring through the bracket
to the motor and the PLA end caps are for off motor
mounting.
